Security to Which This Statement Relates:

Item 2. Identity and Background.
(a)-(c) and (f). This Schedule 13D is filed on behalf of Allan
C. Mulder, a Florida resident individual and a United States
citizen ("Mulder"). Mulder is retired. The principal address of
Mulder is 10618 Spicewood Trail, Boynton Beach, Florida 33436.
(d) and (e). During the last five years, Mulder has not (i) been
convicted in a criminal proceeding (excluding traffic violations
or similar misdemeanors) or (ii) been a party to a civil
proceeding of a judicial or administrative body of competent
jurisdiction and as a result of such proceeding was or is subject
to a judgment, decree or final order enjoining future violations
of, or prohibiting or mandating activities subject to, federal or
state securities laws or finding any violation with respect to
such laws.
Item 3. Source and Amount of Funds or Other Consideration.
On February 28, 1997, Mulder converted 5,000 shares of
Plexus Corp. Class A Preferred Stock ("Plexus Preferred") into
396,039 shares of Plexus Common, in accordance with the terms of
the Plexus Preferred with no further payment required. Mulder
had acquired the Plexus Preferred in 1994 for cash, in a private
placement transaction.
Item 4. Purpose of the Transaction.
Mulder has been a long time investor in Plexus, with his
interest in Plexus having been acquired, and continuing to be,
for investment purposes. Mulder purchased the shares of Plexus
Preferred, and converted those shares into Plexus Common, in
continuation of that long term investment. Mulder may purchase
additional Plexus shares, or dispose of such shares, in market or
private transactions, in the event such actions would be
attractive for investment purposes.
<PAGE>
In June 1995, Mulder was elected by the Plexus board of
directors to a newly created position on the board. Mulder did
not solicit a seat on the Plexus board, but accepted when offered
a board position by Plexus. Mulder resigned from the board in
1996.
Other than the foregoing, Mulder has no plans or proposals
which would result in the acquisition or disposition of Plexus
Common Stock or any other action which is enumerated in Item 4 of
Schedule 13D.
Item 5. Interest in Securities of the Issuer.
(a), (b) and (c).
As of February 5, 1997, Plexus reported outstanding
6,675,000 shares of Plexus Common. Subsequent to that date,
Plexus has informed Mulder that all shares of Plexus Preferred
have been converted, and that 554,454 shares of Plexus Common
were issued in the conversion process. Therefore, Mulder has
assumed that Plexus has 7,229,454 shares of Plexus Common
currently outstanding. Pursuant to the terms of Plexus
Preferred, Mulder had the right to acquire 396,039 shares of
Plexus Common upon full conversion of the Plexus Preferred, which
occurred as of February 28, 1997.
As of February 28, 1997, the undersigned had sold voting and
dispositive power with respect to 580,763 shares of Plexus
Common. Shares of Plexus Common which are beneficially owned by
Mulder represent 8.0% of the currently outstanding shares of
Plexus Common.
Other than the foregoing, there have been no transactions by
Mulder with respect to Plexus Common during the sixty days
preceding the date of this Schedule 13D.
(d). None.
(e). Not Applicable.
Item 6. Contracts, Arrangements, Understandings or
Relationships with Respect to Securities of the Issuer.
Other than the Designation of Series A Preferred Stock
(which is a part of the Articles of Incorporation of Plexus),
there are no contracts, arrangements, understandings or
relationships between Mulder and any other person with respect to
any securities of Plexus.

Item 7. Material to be Filed as Exhibits.

reference the following exhibit:

the quarter ended June 30, 1994.)
