Amphenol® solder contact miniature cylindrical connectors meet the

most critical application needs. Design versatility combined with high

reliability performance makes these series of Miniature Cylindrical

Connectors ideal for environmental sealing or pressurized applications.

The MS/PT Series is qualified to MIL-DTL-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 anodic “Alumilite”® coating which provides abrasion

protection and resistance to corrosion.

**NEW** 500 hour corrosion resistance, RoHS compliant harsh environment

conductive plating. Gray Zinc over an Electroless Nickel (Gray ZnNi) base, with a Light

Gun Metal Gray appearance.

Shell components for these series are aluminum. The dependable 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 gasket 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. A breakaway style plug is

available in the PT solder series. Hermetics receptacles are available in PT and MS/

PT solder series. Receptacles with printed circuit board contacts are also available.

PT Solder is UL recognized under file #E115497, Vol. 1, Sec. 5. The PT, SP and MS/PT

Series are intermateable and intermountable with all existing Miniature Cylindrical

Series connectors.
