Re:  Registration Statement on Form S-8 - 1995 Stock
     Option Plan

Dear Ladies and Gentlemen:

     We have acted as counsel to Datron Systems
Incorporated, a Delaware corporation (the "Company"), in
connection with the Registration Statement on Form S-8
(the "Registration Statement") which the Company
proposes to file with the Securities and Exchange
Commission on or about May 24, 2000 for the purpose of
registering under the Securities Act of 1933, as
amended, 200,000 shares (the "Shares") of Common Stock,
par value $0.01 per share, issuable under the Company's
1995 Stock Option Plan (the "Plan").

     In connection with this opinion, we have assumed
the authenticity of all records, documents and
instruments submitted to us as originals, the
genuineness of all signatures, the legal capacity of
natural persons and the authenticity and conformity to
the originals of all records, documents and instruments
submitted to us as copies.  In addition, the Company has
advised us that, of the 10,000,000 shares common stock
it is authorized to issue, 2,722,261 shares of common
stock are issued and outstanding as of the date of this
opinion.

     We have based our opinion upon our review of the
following records, documents and instruments:

     (a)  The Certificate of Incorporation of the
          Company certified by the Secretary of the
          State of Delaware as of May 24, 2000 and
          certified to us by an officer of the Company
          as being complete and in full force and effect
          as of the date of this opinion;

     (b)  The Bylaws of the Company certified to us by
          an officer of the Company as being complete
          and in full force and effect as of the date of
          this opinion;

     (c)  Resolution of the Board of Directors of the
          Company approving the amendment to the Plan
          authorizing the issuance of options to acquire
          an additional 200,000 Shares;

     (d)  A Certificate of Good Standing from the
          Delaware Secretary of State dated May 24,
          2000;

     (e)  A Certificate of the Company's transfer agent
          as to the number of issued and outstanding
          shares of the Company's Common Stock as of May
          24, 2000;

     (f)  The Registration Statement; and

     (g)  The Plan.

     This opinion is limited to Delaware General
Corporation Law.  We disclaim any opinion as to any
statute, rule, regulation, ordinance, order or other
promulgation of any other jurisdiction or any regional
or local governmental body.

     Based upon the foregoing and our examination of
such questions of law as we have deemed necessary or
appropriate of the purpose of this opinion, and assuming
that (i) the Registration Statement becomes and remains
effective during the period when the Shares are offered
and sold, (ii) the full consideration stated in the Plan
is paid for each Share and (iii) all applicable
securities laws are complied with, it is our opinion
that, when issued and sold by the Company, and after
payment therefor in the manner provided in the Plan, the
Shares will be validly issued, fully paid and
nonassessable.

     This opinion is rendered to you in connection with
the issuance of the Shares and is solely for your
benefit.  This opinion may not be relied upon by you for
any other purpose, or relied upon by any other person,
firm, corporation or other entity for any purpose,
without our prior written consent.  We disclaim any
obligation to advise you of any developments in areas
covered by this opinion that occur after the date of
this opinion.

     We hereby consent to the filing of this opinion as
an exhibit to the Registration Statement.

                              Very truly yours,



                              Heller Ehrman White &
                              McAuliffe LLP
