meet the most critical application needs. Design versatility

combined with high reliability performance makes these

series of Miniature Cylindrical Connectors ideal for envi-

ronmental sealing or pressurized applications.

The MS/PT Series is qualified to MIL-C-26482, Series 1 and

has all the outstanding design characteristics and quality of the

PT Series. The SP Series is a modification of the PT, providing

special shells with a wide mounting flange for back panel

mounting.

A corrosion resistant electrically conductive finish of cadmium

plate with an olive drab chromate after-treatment is used on the

PT and MS/PT. The SP is given a durable non-conductive hard

and resistance to corrosion.

Shell components for these series are aluminum. The depend-

able 5 key/keyway polarization with bayonet lock coupling

assures positive mating with no chance of cross plugging.

Spring tension provided by a wave washer in the coupling nut

ensures maintenance of interfacial seal between mating halves.

Both the insert and main joint gasket are molded from resilient

neoprene. This provides excellent moisture sealing at the gas-

ket and superior electrical isolation of the contact in the insert.

Both pins and sockets are machined from a copper alloy and

are gold plated. This gold plating eliminates contact corrosion

and offers an indefinite shelf life. Socket contacts for these

series are a closed entry design. Printed circuit board contacts

are also available.

The PT, SP and MS/PT Series are intermateable and inter-

mountable with all existing Miniature Cylindrical Series connec-

tors except for the threaded coupling PC Series.

PT Solder is UL recognized under file #E115497, Volume 1,

Section 5.

* This connector style is sometimes referred to as a cable connecting “plug.”

It does, however, mate with a straight or 90 degree plug.
