Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business Description and Basis of Presentation	Business Description and Basis of Presentation Description of Business The accompanying unaudited condensed consolidated financial statements reflect the financial position, results of operations, comprehensive income, and cash flows of Sensata Technologies Holding plc ("Sensata plc"), the successor issuer to Sensata Technologies Holding N.V. ("Sensata N.V."), and its wholly-owned subsidiaries, collectively referred to as the "Company," "Sensata," "we," "our," or "us." On September 28, 2017, the Board of Directors of Sensata N.V. unanimously approved a plan to change our location of incorporation from the Netherlands to the United Kingdom (the "U.K."). To effect this change, on February 16, 2018, the shareholders of Sensata N.V. approved a cross-border merger between Sensata N.V. and Sensata plc, a newly formed, public limited company incorporated under the laws of England and Wales, with Sensata plc being the surviving entity (the "Merger"). We received approval of the transaction by the U.K. High Court of Justice, and the Merger was completed on March 28, 2018, on which date Sensata plc became the publicly-traded parent of the subsidiary companies that were previously controlled by Sensata N.V., with no changes made to the business being conducted by us prior to the Merger. Due to the fact that the Merger was a business combination between entities under common control, in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 805, Business Combinations , the assets and liabilities exchanged were accounted for at their carrying values. Sensata plc conducts its operations through subsidiary companies that operate business and product development centers primarily in the United States (the "U.S."), the U.K., Belgium, Bulgaria, China, Germany, Japan, the Netherlands, and South Korea; and manufacturing operations primarily in China, Malaysia, Mexico, Bulgaria, Germany, the U.K., and the U.S. We organize our operations into two segments, Performance Sensing and Sensing Solutions. Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP") for interim financial information and the instructions to Form 10-Q. Accordingly, these interim financial statements do not include all of the information and note disclosures required by U.S. GAAP for complete financial statements. The accompanying financial information reflects all normal recurring adjustments that are, in the opinion of management, necessary for a fair presentation of the interim period results. The results of operations for the three and nine months ended September 30, 2018 are not necessarily indicative of the results to be expected for the full year, nor were the results of operations of the comparable periods in 2017 necessarily representative of those actually experienced for the full year 2017 . These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2017 . All intercompany balances and transactions have been eliminated. All U.S. dollar and share amounts presented, except per share amounts, are stated in thousands, unless otherwise indicated. Certain reclassifications have been made to prior periods to conform to current period presentation.

New Accounting Standards

New Accounting Standards	Sep. 30, 2018
New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Standards	New Accounting Standards Adopted in the current year In May 2014, the FASB issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers (Topic 606) , which modifies how all entities recognize revenue, and consolidates into one ASC Topic (that is, FASB ASC Topic 606, Revenue from Contracts with Customers ) the guidance found in FASB ASC Topic 605, Revenue Recognition , and various other revenue accounting standards for specialized transactions and industries. FASB ASC Topic 606 outlines a comprehensive five-step revenue recognition model based on the principle that an entity should recognize revenue to depict the transfer of promised goods or services to customers at an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. We adopted FASB ASC Topic 606 on January 1, 2018 using the modified retrospective transition method. Refer to Note 16, "Revenue Recognition," for additional details on this implementation and the required disclosures. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10), Recognition and Measurement of Financial Assets and Financial Liabilities , which addresses certain aspects of the recognition, measurement, presentation, and disclosure of financial instruments. The new recognition and measurement guidance requires entities to measure equity investments (other than those accounted for under the equity method, those that result in consolidation of the investee, and certain other investments) either at fair value, with changes to fair value recognized in net income, or in certain instances, by use of a measurement alternative. Under the measurement alternative, such investments are measured at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for an identical or similar investment of the same issuer. We adopted this guidance on January 1, 2018, which resulted in no impact on our consolidated financial position or results of operations. Refer to Note 11, "Fair Value Measures," for further detail regarding the application of the measurement alternative to our $50.0 million equity investment in Series B Preferred Stock of Quanergy, Inc ("Quanergy"). In March 2017, the FASB issued ASU No. 2017-07, Compensation - Retirement Benefits (Topic 715), Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost , which requires a change in the presentation of net periodic benefit cost on the consolidated statements of operations. Specifically, entities must present the service cost component of net periodic benefit cost in the same financial statement line item(s) as other compensation costs arising from services rendered by the related employees during the period, whereas the non–service components of net periodic benefit cost must be presented separately from the financial statement line item(s) that include service cost and outside of operating income. We adopted this guidance on January 1, 2018 and, as a result, we present the service cost component of net periodic benefit cost in the Cost of revenue, Research and development, and Selling, general, and administrative ("SG&A") expense line items, and we present the non–service components of net periodic benefit cost in Other, net. Refer to Note 13, "Other, Net," for the total other components of net periodic benefit cost. All prior period amounts have been recast to reflect the revised presentation, and the adjustments made to revise the presentation of our prior year condensed consolidated statement of operations are presented in Note 8, "Pension and Other Post–Retirement Benefits." To be adopted in a future period In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) , which establishes new accounting and disclosure requirements for leases. FASB ASU No. 2016-02 requires lessees to classify most leases as either finance or operating leases and to initially recognize a lease liability and right-of-use asset. Entities may elect to account for certain short-term leases (with a term of one year or less) using a method similar to the current operating lease model. The statement of operations will include, for finance leases, separate recognition of interest on the lease liability and amortization of the right-of-use asset and for operating leases, a single lease cost, calculated so that the cost of the lease is allocated over the lease term on a straight-line basis. FASB ASU No. 2016-02 is effective for annual reporting periods beginning after December 15, 2018, including interim periods therein, with early adoption permitted. We are in the process of implementing a plan for the adoption of FASB ASU No. 2016-02. Through our implementation efforts, we have decided that we will elect to apply the package of practical expedients, and we will not elect to apply the hindsight practical expedient. In July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842), Targeted Improvements , which creates an optional transition expedient that allows an entity to apply the transition provisions of the new standard, including its disclosure requirements, at its adoption date instead of at the beginning of the earliest comparative period presented as originally required by FASB ASU No. 2016-02. We will adopt FASB ASU No. 2016-02 on January 1, 2019 using this transition expedient. We expect that adoption of this standard will result in the recognition of a lease liability and right-of-use asset for certain operating leases that are currently not recognized on our condensed consolidated balance sheets. At December 31, 2017, we were contractually obligated to make future payments of $68.6 million under our operating lease obligations in existence as of that date, primarily related to long-term facility leases. In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815) , which changes both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results, in order to better align an entity’s risk management activities and financial reporting for hedging relationships. The amendments expand and refine hedge accounting for both nonfinancial and financial risk components and align the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. FASB ASU No. 2017-12 is effective for annual reporting periods beginning after December 15, 2018, including interim periods within those annual reporting periods, with early adoption permitted. The adoption of FASB ASU No. 2017-12 will not have a material impact on our consolidated financial position or results of operations. Revenue Recognition As described in Note 2, "New Accounting Standards," we adopted FASB ASC Topic 606 on January 1, 2018, and we applied the pertinent transition provisions to contracts that were not completed as of January 1, 2018 using the modified retrospective method. Because (1) the vast majority of our revenue is derived from the sale of tangible products for which we recognize revenue at a point in time and (2) the contracts that relate to these product shipments are purchase orders that have firm purchase commitments (generally over a short period of time), the adoption of FASB ASC Topic 606 did not have a material effect on our financial statements or results of operations, and no cumulative catch-up adjustment was required. We are electing to apply certain practical expedients that allow for more limited disclosures than those that would otherwise be required by FASB ASC Topic 606, including (1) the disclosure of transaction price allocated to the remaining unsatisfied performance obligations at the end of the period and (2) an explanation of when we expect to recognize the related revenue.

Revenue is recognized when control of the product is transferred to the customer, which is generally when the product is shipped from our warehouse or, in limited instances, when it is received by the customer, depending on the specific terms of the arrangement. Payment for products is generally due a short time (that is, less than a year) after shipment to the customer. Sales to customers generally include a right of return for defective or non-conforming product. Sales returns have not historically been significant in relation to our net revenue and have been within our estimates. Product sales are recorded net of variable consideration, such as sales returns and trade discounts (including volume and early payment incentives), as well as value-added tax and similar taxes. Amounts billed to our customers for shipping and handling are recorded in revenue. Shipping and handling costs are included in cost of revenue. Warranties Our standard terms of sale provide our customers with a warranty against faulty workmanship and the use of defective materials, which, depending on the product, generally exists for a period of twelve to eighteen months after the date we ship the product to our customer or for a period of twelve months after the date the customer resells our product, whichever comes first. We do not offer separately priced extended warranty or product maintenance contracts. Our liability associated with this warranty is, at our option, to repair the product, replace the product, or provide the customer with a credit. We also sell products to customers under negotiated agreements or where we have accepted the customer’s terms of purchase. In these instances, we may provide additional warranties for longer durations, consistent with differing end market practices, and where our liability is not limited. In addition, many sales take place in situations where commercial or civil codes, or other laws, would imply various warranties and restrict limitations on liability. Contract Assets and Liabilities Our contract assets consist of accounts receivable. Contract liabilities, whereby we receive payment from customers related to our promise to satisfy performance obligations in the future, are not material.

Shareholders' Equity

Shareholders' Equity	Sep. 30, 2018
Equity [Abstract]
Shareholders' Equity	Shareholders' Equity Prior to the Merger, Sensata N.V.’s articles of association authorized it to issue up to 400.0 million ordinary shares. However, entities incorporated under the laws of England and Wales are limited in the number of shares they can issue to those shares that have been authorized for "allotment" by their shareholders. In connection with the Merger, our Board of Directors asked shareholders to approve an allotment of ordinary shares equal to the total ordinary shares then issued and outstanding plus the maximum number of ordinary shares that could be reasonably expected to be issued under our equity plans within the next year, which resulted in an allotment of 177.1 million ordinary shares. Treasury Shares Ordinary shares repurchased by us are recognized, measured at cost, and presented as treasury shares on our condensed consolidated balance sheets, resulting in a reduction of shareholders' equity. In connection with the Merger, all then outstanding treasury shares were canceled in accordance with U.K. law. Accordingly, we (1) derecognized the total purchase price of these treasury shares, (2) recognized a reduction to ordinary shares at an amount equal to the total par value of such shares, and (3) recognized a reduction to Retained earnings at an amount equal to the excess of the total repurchase price over the total par value of the then outstanding treasury shares, or $286.1 million . Also, upon completion of the Merger, the $250.0 million share repurchase program previously authorized by the Board of Directors of Sensata N.V. lapsed, and our ability to repurchase shares as a company incorporated in England and Wales became contingent upon the completion of certain court proceedings in the U.K. (which were completed in the second quarter of 2018), approval of our shareholders (which occurred at our May 31, 2018 annual general meeting of shareholders), and authorization by our Board of Directors. On May 31, 2018, we announced that our Board of Directors had authorized a $400.0 million share repurchase program. Under this program, we may repurchase ordinary shares at such times and in amounts to be determined by our management, based on market conditions, legal requirements, and other corporate considerations, on the open market or in privately negotiated transactions, provided that such transactions are completed pursuant to an agreement and with a third party approved by our shareholders at the annual general meeting. The authorized amount of our share repurchase program may be modified or terminated by our Board of Directors at any time. We repurchased 7,571 ordinary shares under this program during the nine months ended September 30, 2018 , for a total purchase price of approximately $399.4 million , which are now held as treasury shares. As a result of certain aspects of U.K. law, we discontinued the practice of reissuing treasury shares as part of our share-based compensation programs upon completion of the Merger. The number of treasury shares reissued prior to completion of the Merger was not material. In October 2018, our Board of Directors authorized a new $250.0 million share repurchase program, subject to the same conditions that applied to the previously authorized $400.0 million share repurchase program.

We applied the provisions of FASB ASC Subtopic 470-50, Modifications and Extinguishments, in accounting for the amounts paid. As a result, we recorded an adjustment of $3.5 million to the carrying amount of Long-term debt, net, and we recognized a loss of $2.4 million in Other, net. As of September 30, 2018 , we had $416.0 million available under our $420.0 million revolving credit facility, net of $4.0 million in letters of credit. Outstanding letters of credit are issued primarily for the benefit of certain operating activities. As of September 30, 2018 , no amounts had been drawn against these outstanding letters of credit. Accrued Interest Accrued interest associated with our outstanding debt is included as a component of Accrued expenses and other current liabilities in the condensed consolidated balance sheets.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Provision for income taxes for the three months ended September 30, 2018 and 2017 totaled $24.6 million and $14.8 million , respectively, and for the nine months ended September 30, 2018 and 2017 totaled $62.1 million and $47.8 million , respectively. The Provision for income taxes consists of current tax expense, which relates primarily to our profitable operations in non-U.S. tax jurisdictions, and deferred tax expense, which relates to adjustments in book-to-tax basis differences primarily due to the step-up in fair value of fixed and intangible assets, including goodwill, acquired in connection with business combination transactions, and the utilization of net operating losses. On December 22, 2017, the Tax Cuts and Jobs Act of 2017 ("Tax Reform" or "the Act") was signed into U.S. law. FASB ASC Topic 740, Accounting for Income Taxes , requires companies to recognize the effect of tax law changes in the period of enactment even though the effective date for most provisions is for tax years beginning after December 31, 2017. Given the significance of the legislation, the U.S. Securities and Exchange Commission (the "SEC") staff issued Staff Accounting Bulletin No.118 ("SAB 118"), which allows registrants to record provisional amounts during a one-year "measurement period" similar to that used when accounting for business combinations. However, the measurement period is deemed to have ended earlier when the registrant has obtained, prepared, and analyzed the information necessary to finalize its accounting. During the measurement period, impacts of the law are expected to be recorded at the time a reasonable estimate for all or a portion of the effects can be made, and provisional amounts can be recognized and adjusted as information becomes available, prepared, or analyzed. As of September 30, 2018 , we have not recorded incremental accounting adjustments related to the Act. We continue to consider interpretations of its application and await final guidance on the application of specific elements of the Act. In measuring the related deferred tax assets, we consider all available evidence, both positive and negative, to determine whether, based on the weight of that evidence, a valuation allowance is needed for all or some portion of the deferred tax assets. Significant judgment is required in considering the relative impact of the negative and positive evidence, and weight given to each category of evidence is commensurate with the extent to which it can be objectively verified. The greater negative evidence that exists, more positive evidence is necessary to support a conclusion that a valuation allowance is not needed. Additionally, we utilize the "more likely than not" criteria established in FASB ASC Topic 740, Income Taxes , to determine whether the future tax benefit from the deferred tax assets should be recognized. As a result, we maintain a full valuation allowance on the deferred tax assets in jurisdictions that have incurred net operating losses and in which it is more likely than not that such losses will not be utilized in the foreseeable future. We have concluded that a valuation allowance is required on our deferred tax assets in the U.S., in large part due to the cumulative losses that our U.S. operations have experienced in recent years. Such cumulative losses are negative evidence that is difficult to overcome in concluding whether a valuation allowance is required. We continue to assess both positive and negative evidence surrounding our U.S. operations, and to evaluate the impact of Tax Reform on our tax attributes and related valuation allowance implications. As a consequence of our assessment, we have concluded that maintaining the U.S. valuation allowance is appropriate as of September 30, 2018 .

Commitments and Contingencies	Commitments and Contingencies We are the defendant in a lawsuit, Wasica Finance Gmbh et al v. Schrader International Inc. et al, Case No. 13-1353-CPS, U.S.D.C., Delaware , in which the claimant alleges infringement of their patent (US 5,602,524) in connection with our TPMS products. The patent in question has expired, and as a result, the claimant only seeks damages for past infringement with interest and costs. Should the claimant prevail, these amounts could be material. We have denied liability and have been defending the litigation, which is in discovery. The court has currently scheduled a claims construction hearing for December 2018 and trial for February 2020. We do not believe a loss related to this matter is probable. As of September 30, 2018 , we have not recorded an accrual for this matter. We are regularly involved in a number of claims and litigation matters in the ordinary course of business, primarily related to allegations of intellectual property infringement and property damage or personal injury caused by our products. Although it is not feasible to predict the outcome of these matters, based upon our experience and current information known to us, we do not expect the outcome of these matters, either individually or in the aggregate, to have a material adverse effect on our results of operations, financial position, or cash flows.

Fair Value Measures	Fair Value Measures Our assets and liabilities recorded at fair value have been categorized based upon the fair value hierarchy in accordance with FASB ASC Topic 820, Fair Value Measurement . Measured on a Recurring Basis The fair values of our assets and liabilities measured at fair value on a recurring basis as of September 30, 2018 and December 31, 2017 are as shown in the below table. All fair value measures presented are categorized in Level 2 of the fair value hierarchy.

In connection with the sale of the Valves Business, which is described in Note 17, "Acquisitions and Divestitures," and as required by FASB ASC Topic 350, we evaluated the goodwill of the retained portion of the Performance Sensing reporting unit for impairment and determined that it was not impaired. We periodically reevaluate the carrying values and estimated useful lives of long-lived assets whenever events or changes in circumstances indicate that the carrying values of such assets may not be recoverable. On January 1, 2018, we adopted FASB ASU No. 2016-01, which requires that equity investments (other than those accounted for under the equity method, those that result in consolidation of the investee, and certain other investments) be measured at either fair value, with changes to fair value recognized in net income, or in certain instances, by use of a measurement alternative. Under the measurement alternative, such investments are measured at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for an identical or similar investment of the same issuer. As it relates to our $50.0 million equity investment in Quanergy, we elected to use the measurement alternative. As of September 30, 2018 , we noted no material observable price changes as a result of orderly transactions for an identical or similar investment of the same issuer, nor did we note any indicators of impairment that would require us to measure the fair value of the asset. Financial Instruments Not Recorded at Fair Value The following table presents the carrying values and fair values of financial instruments not recorded at fair value in the condensed consolidated balance sheets as of September 30, 2018 and December 31, 2017 .

Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities Hedges of Foreign Currency Risk We are exposed to fluctuations in various foreign currencies against our functional currency, the U.S. dollar. We use foreign currency forward agreements to manage this exposure. We currently have outstanding foreign currency forward contracts that qualify as cash flow hedges and are intended to offset the effect of exchange rate fluctuations on forecasted sales and certain manufacturing costs. We also have outstanding foreign currency forward contracts that are not designated for hedge accounting treatment in accordance with FASB ASC Topic 815, Derivatives and Hedging , and are intended to preserve the economic value of foreign currency denominated monetary assets and liabilities. For the three and nine months ended September 30, 2018 and 2017, amounts excluded from the assessment of effectiveness and the ineffective portion of the changes in the fair value of our foreign currency forward agreements that are designated as cash flow hedges were not material.

Segment Reporting [Abstract]
Segment Reporting	Segment Reporting We organize our business into two reportable segments, Performance Sensing and Sensing Solutions, each of which is also an operating segment. Our operating segments are businesses that we manage as components of an enterprise for which separate financial information is evaluated regularly by our chief operating decision maker in deciding how to allocate resources and assess performance. An operating segment’s performance is primarily evaluated based on Segment profit, which excludes Amortization of intangible assets, Restructuring and other charges, net, and certain corporate costs/credits not associated with the operations of the segment, including share-based compensation expense and a portion of depreciation expense associated with assets recorded in connection with acquisitions. In addition, an operating segment’s performance excludes results from discontinued operations, if any. Corporate and other costs excluded from an operating segment’s performance are separately stated below and also include costs that are related to functional areas, such as finance, information technology, legal, and human resources. We believe that Segment profit, as defined above, is an appropriate measure for evaluating the operating performance of our segments. However, this measure should be considered in addition to, and not as a substitute for, or superior to, profit from operations or other measures of financial performance prepared in accordance with U.S. GAAP. The accounting policies of each of our reporting segments are materially consistent with those in the summary of significant accounting policies as described in Note 2, "Significant Accounting Policies," included in our Annual Report on Form 10-K for the year ended December 31, 2017 . The following table presents Net revenue and Segment profit for the reported segments and other operating results not allocated to the reported segments for the three and nine months ended September 30, 2018 and 2017: For the three months ended For the nine months ended September 30, 2018 September 30, 2017 September 30, 2018 September 30, 2017 Net revenue: Performance Sensing $ 649,611 $ 603,932 $ 1,988,657 $ 1,825,904 Sensing Solutions 223,941 215,122 685,048 640,295 Total net revenue $ 873,552 $ 819,054 $ 2,673,705 $ 2,466,199 Segment profit (as defined above): Performance Sensing $ 178,391 $ 162,655 $ 535,166 $ 483,491 Sensing Solutions 73,295 72,372 224,249 209,911 Total segment profit 251,686 235,027 759,415 693,402 Corporate and other (48,154 ) (53,101 ) (156,472 ) (151,181 ) Amortization of intangible assets (33,911 ) (40,317 ) (103,574 ) (121,578 ) Restructuring and other charges, net 52,698 (1,329 ) 48,688 (18,768 ) Profit from operations 222,319 140,280 548,057 401,875 Interest expense, net (38,058 ) (40,263 ) (114,808 ) (120,578 ) Other, net (10,581 ) 2,834 (26,267 ) 5,690 Income before taxes $ 173,680 $ 102,851 $ 406,982 $ 286,987

Net Income per Share	Net Income per Share Basic and diluted net income per share are calculated by dividing Net income by the number of basic and diluted weighted-average ordinary shares outstanding during the period. For the three and nine months ended September 30, 2018 and 2017, the weighted-average ordinary shares outstanding for basic and diluted net income per share were as follows: For the three months ended For the nine months ended September 30, September 30, September 30, September 30, Basic weighted-average ordinary shares outstanding 167,290 171,269 170,045 171,116 Dilutive effect of stock options 886 618 898 567 Dilutive effect of unvested restricted securities 418 358 438 340 Diluted weighted-average ordinary shares outstanding 168,594 172,245 171,381 172,023 Net income and net income per share are presented in the condensed consolidated statements of operations. Certain potential ordinary shares were excluded from our calculation of diluted weighted-average ordinary shares outstanding because either they would have had an anti–dilutive effect on net income per share or they related to equity awards that were contingently issuable for which the contingency had not been satisfied. These potential ordinary shares are as follows: For the three months ended For the nine months ended September 30, September 30, September 30, September 30, Anti-dilutive shares excluded 983 1,584 894 1,635 Contingently issuable shares excluded 807 884 801 783

Revenue Recognition and Deferred Revenue [Abstract]
Revenue Recognition	New Accounting Standards Adopted in the current year In May 2014, the FASB issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers (Topic 606) , which modifies how all entities recognize revenue, and consolidates into one ASC Topic (that is, FASB ASC Topic 606, Revenue from Contracts with Customers ) the guidance found in FASB ASC Topic 605, Revenue Recognition , and various other revenue accounting standards for specialized transactions and industries. FASB ASC Topic 606 outlines a comprehensive five-step revenue recognition model based on the principle that an entity should recognize revenue to depict the transfer of promised goods or services to customers at an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. We adopted FASB ASC Topic 606 on January 1, 2018 using the modified retrospective transition method. Refer to Note 16, "Revenue Recognition," for additional details on this implementation and the required disclosures. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10), Recognition and Measurement of Financial Assets and Financial Liabilities , which addresses certain aspects of the recognition, measurement, presentation, and disclosure of financial instruments. The new recognition and measurement guidance requires entities to measure equity investments (other than those accounted for under the equity method, those that result in consolidation of the investee, and certain other investments) either at fair value, with changes to fair value recognized in net income, or in certain instances, by use of a measurement alternative. Under the measurement alternative, such investments are measured at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for an identical or similar investment of the same issuer. We adopted this guidance on January 1, 2018, which resulted in no impact on our consolidated financial position or results of operations. Refer to Note 11, "Fair Value Measures," for further detail regarding the application of the measurement alternative to our $50.0 million equity investment in Series B Preferred Stock of Quanergy, Inc ("Quanergy"). In March 2017, the FASB issued ASU No. 2017-07, Compensation - Retirement Benefits (Topic 715), Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost , which requires a change in the presentation of net periodic benefit cost on the consolidated statements of operations. Specifically, entities must present the service cost component of net periodic benefit cost in the same financial statement line item(s) as other compensation costs arising from services rendered by the related employees during the period, whereas the non–service components of net periodic benefit cost must be presented separately from the financial statement line item(s) that include service cost and outside of operating income. We adopted this guidance on January 1, 2018 and, as a result, we present the service cost component of net periodic benefit cost in the Cost of revenue, Research and development, and Selling, general, and administrative ("SG&A") expense line items, and we present the non–service components of net periodic benefit cost in Other, net. Refer to Note 13, "Other, Net," for the total other components of net periodic benefit cost. All prior period amounts have been recast to reflect the revised presentation, and the adjustments made to revise the presentation of our prior year condensed consolidated statement of operations are presented in Note 8, "Pension and Other Post–Retirement Benefits." To be adopted in a future period In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) , which establishes new accounting and disclosure requirements for leases. FASB ASU No. 2016-02 requires lessees to classify most leases as either finance or operating leases and to initially recognize a lease liability and right-of-use asset. Entities may elect to account for certain short-term leases (with a term of one year or less) using a method similar to the current operating lease model. The statement of operations will include, for finance leases, separate recognition of interest on the lease liability and amortization of the right-of-use asset and for operating leases, a single lease cost, calculated so that the cost of the lease is allocated over the lease term on a straight-line basis. FASB ASU No. 2016-02 is effective for annual reporting periods beginning after December 15, 2018, including interim periods therein, with early adoption permitted. We are in the process of implementing a plan for the adoption of FASB ASU No. 2016-02. Through our implementation efforts, we have decided that we will elect to apply the package of practical expedients, and we will not elect to apply the hindsight practical expedient. In July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842), Targeted Improvements , which creates an optional transition expedient that allows an entity to apply the transition provisions of the new standard, including its disclosure requirements, at its adoption date instead of at the beginning of the earliest comparative period presented as originally required by FASB ASU No. 2016-02. We will adopt FASB ASU No. 2016-02 on January 1, 2019 using this transition expedient. We expect that adoption of this standard will result in the recognition of a lease liability and right-of-use asset for certain operating leases that are currently not recognized on our condensed consolidated balance sheets. At December 31, 2017, we were contractually obligated to make future payments of $68.6 million under our operating lease obligations in existence as of that date, primarily related to long-term facility leases. In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815) , which changes both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results, in order to better align an entity’s risk management activities and financial reporting for hedging relationships. The amendments expand and refine hedge accounting for both nonfinancial and financial risk components and align the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. FASB ASU No. 2017-12 is effective for annual reporting periods beginning after December 15, 2018, including interim periods within those annual reporting periods, with early adoption permitted. The adoption of FASB ASU No. 2017-12 will not have a material impact on our consolidated financial position or results of operations. Revenue Recognition As described in Note 2, "New Accounting Standards," we adopted FASB ASC Topic 606 on January 1, 2018, and we applied the pertinent transition provisions to contracts that were not completed as of January 1, 2018 using the modified retrospective method. Because (1) the vast majority of our revenue is derived from the sale of tangible products for which we recognize revenue at a point in time and (2) the contracts that relate to these product shipments are purchase orders that have firm purchase commitments (generally over a short period of time), the adoption of FASB ASC Topic 606 did not have a material effect on our financial statements or results of operations, and no cumulative catch-up adjustment was required. We are electing to apply certain practical expedients that allow for more limited disclosures than those that would otherwise be required by FASB ASC Topic 606, including (1) the disclosure of transaction price allocated to the remaining unsatisfied performance obligations at the end of the period and (2) an explanation of when we expect to recognize the related revenue. The following tables present revenue by segment, further disaggregated by end market: For the three months ended September 30, 2018 For the three months ended September 30, 2017 Performance Sensing Sensing Solutions Total Performance Sensing Sensing Solutions Total Automotive $ 507,961 $ 11,544 $ 519,505 $ 485,277 $ 11,809 $ 497,086 HVOR 141,650 — 141,650 118,655 — 118,655 Appliance and HVAC — 53,505 53,505 — 51,976 51,976 Industrial — 84,057 84,057 — 78,424 78,424 Aerospace — 41,062 41,062 — 38,249 38,249 Other — 33,773 33,773 — 34,664 34,664 Total $ 649,611 $ 223,941 $ 873,552 $ 603,932 $ 215,122 $ 819,054 For the nine months ended September 30, 2018 For the nine months ended September 30, 2017 Performance Sensing Sensing Solutions Total Performance Sensing Sensing Solutions Total Automotive $ 1,570,340 $ 38,402 $ 1,608,742 $ 1,471,338 $ 38,143 $ 1,509,481 HVOR 418,317 — 418,317 354,566 — 354,566 Appliance and HVAC — 164,432 164,432 — 161,129 161,129 Industrial — 253,289 253,289 — 235,853 235,853 Aerospace — 123,268 123,268 — 113,305 113,305 Other — 105,657 105,657 — 91,865 91,865 Total $ 1,988,657 $ 685,048 $ 2,673,705 $ 1,825,904 $ 640,295 $ 2,466,199 Performance Obligations Our revenue and related cost of revenue are primarily the result of promises to transfer products to our customers. Revenue is recognized when control of the product is transferred to the customer, which is generally when the product is shipped from our warehouse or, in limited instances, when it is received by the customer, depending on the specific terms of the arrangement. Payment for products is generally due a short time (that is, less than a year) after shipment to the customer. Sales to customers generally include a right of return for defective or non-conforming product. Sales returns have not historically been significant in relation to our net revenue and have been within our estimates. Product sales are recorded net of variable consideration, such as sales returns and trade discounts (including volume and early payment incentives), as well as value-added tax and similar taxes. Amounts billed to our customers for shipping and handling are recorded in revenue. Shipping and handling costs are included in cost of revenue. Warranties Our standard terms of sale provide our customers with a warranty against faulty workmanship and the use of defective materials, which, depending on the product, generally exists for a period of twelve to eighteen months after the date we ship the product to our customer or for a period of twelve months after the date the customer resells our product, whichever comes first. We do not offer separately priced extended warranty or product maintenance contracts. Our liability associated with this warranty is, at our option, to repair the product, replace the product, or provide the customer with a credit. We also sell products to customers under negotiated agreements or where we have accepted the customer’s terms of purchase. In these instances, we may provide additional warranties for longer durations, consistent with differing end market practices, and where our liability is not limited. In addition, many sales take place in situations where commercial or civil codes, or other laws, would imply various warranties and restrict limitations on liability. Contract Assets and Liabilities Our contract assets consist of accounts receivable. Contract liabilities, whereby we receive payment from customers related to our promise to satisfy performance obligations in the future, are not material.

Acquisitions and Divestitures	Acquisitions and Divestitures GIGAVAC acquisition On September 24, 2018, we entered into an agreement and plan of merger with GIGAVAC, LLC (“GIGAVAC”). According to the agreement, in exchange for cash consideration of $233 million to be paid by Sensata, subject to working capital and other adjustments, GIGAVAC will merge with one of our wholly-owned subsidiaries thereby becoming a wholly-owned subsidiary of Sensata (the “GIGAVAC Merger”). We expect the GIGAVAC Merger to close in the fourth quarter of 2018, and we intend to use cash on hand to finance the acquisition. GIGAVAC is a leading provider of solutions that enable electrification in demanding environments within the automotive, battery storage, industrial, and HVOR markets. Valves Business Divestiture On August 31, 2018, we completed the sale of the capital stock of Schrader Bridgeport International, Inc. and August France Holding Company SAS (collectively, the “Valves Business”) to Pacific Industrial Co. Ltd. (together with its affiliates, “Pacific”). Contemporaneous with the closing of the sale, Sensata and Pacific entered into a long-term supply agreement, which imposes an obligation on us to purchase minimum quantities of product from Pacific over a period of nearly five years. In exchange for selling the Valves Business and entering into the long-term supply agreement, we received cash consideration from Pacific of approximately $165.5 million , net of $11.8 million of cash and cash equivalents sold. We recognized a (pre-tax) gain on sale of $63.7 million , which is presented in Restructuring and other charges, net. In addition, we recognized $5.9 million of costs to sell the Valves Business, which are also presented in Restructuring and other charges, net. The terms of the long-term supply agreement, entered into concurrent with the sale of the Valves Business, we determined were not at market. Accordingly, we recognized a liability of $16.4 million , measured at fair value, which represented the fair value of the off-market component of the supply agreement. The Valves Business, which we acquired in 2014 as part of our acquisition of Schrader, manufactures mechanical valves for pressure applications in tires and fluid controls and assembles tire hardware aftermarket products. The Valves Business has manufacturing locations in the United States and Europe. The Valves Business was included in our Performance Sensing segment (and reporting unit). We allocated goodwill to the Valves Business based on its fair value relative to the fair value of the retained Performance Sensing reporting unit.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP") for interim financial information and the instructions to Form 10-Q. Accordingly, these interim financial statements do not include all of the information and note disclosures required by U.S. GAAP for complete financial statements. The accompanying financial information reflects all normal recurring adjustments that are, in the opinion of management, necessary for a fair presentation of the interim period results. The results of operations for the three and nine months ended September 30, 2018 are not necessarily indicative of the results to be expected for the full year, nor were the results of operations of the comparable periods in 2017 necessarily representative of those actually experienced for the full year 2017 . These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2017 . All intercompany balances and transactions have been eliminated. All U.S. dollar and share amounts presented, except per share amounts, are stated in thousands, unless otherwise indicated.

In July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842), Targeted Improvements , which creates an optional transition expedient that allows an entity to apply the transition provisions of the new standard, including its disclosure requirements, at its adoption date instead of at the beginning of the earliest comparative period presented as originally required by FASB ASU No. 2016-02. We will adopt FASB ASU No. 2016-02 on January 1, 2019 using this transition expedient. We expect that adoption of this standard will result in the recognition of a lease liability and right-of-use asset for certain operating leases that are currently not recognized on our condensed consolidated balance sheets. At December 31, 2017, we were contractually obligated to make future payments of $68.6 million under our operating lease obligations in existence as of that date, primarily related to long-term facility leases. In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815) , which changes both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results, in order to better align an entity’s risk management activities and financial reporting for hedging relationships. The amendments expand and refine hedge accounting for both nonfinancial and financial risk components and align the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. FASB ASU No. 2017-12 is effective for annual reporting periods beginning after December 15, 2018, including interim periods within those annual reporting periods, with early adoption permitted. The adoption of FASB ASU No. 2017-12 will not have a material impact on our consolidated financial position or results of operations.
