Amphenol PT, SP, MS/PT
Proprietary/MIL-DTL-26482, Series 1
bayonet coupling and solder termination
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
environ mental sealing or pressurized applications.
The MS/PT Series is qualied to MIL-DTL-26482, Series 1 and has all the outstanding
design characteristics and quality of the PT Series. The SP Series is a modication of
the PT, providing special shells with a wide mounting ange for back panel mounting.
A corrosion resistant electrically conductive nish 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 resis tance 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 pos itive mating with no chance of cross
plugging. Spring tension pro vided 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 indenite 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 le #E115497, Vol. 1, Sec. 5.
The PT, SP and MS/PT Series are intermateable and intermount able with all existing
Miniature Cylindrical Series connectors.
Refer to pages 4-10 for insert arrangement availability.

style is sometimes
referred to as a

“plug.” It does,
however, mate
with a straight or
