Amphenol ® PT-SE, SP-SE, MS/PT-SE
Proprietary/MIL-C-26482, Series 1
bayonet coupling and crimp termination
Amphenol® SE crimp type miniature connectors provide
performance and versatility needed for applications
demanding high reliability and crimp removable contacts.
These crimp contacts are rear insertable/front release and
are held in position by an MS approved spring tower retention system.

The MS/PT-SE Series is qualified to MIL-C-26482, Series 1 and
has all the outstanding design characteristics and quality of the
PT Series.
The SP-SE Series is a modification of the PT-SE, 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-SE and MS/PT-SE. The SP-SE is given a durable non-conductive hard anodic “Alumilite”® coating which provides abrasion protection and resistance to corrosion.
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.
Breakaway style plug is available in PT-SE crimp.
The PT-SE, SP-SE and MS/PT-SE Series are intermateable
and intermountable with all existing Miniature Cylindrical Series
connectors except for the threaded coupling PC Series.
