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 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 anodic
“Alumilite”
tance to corrosion.
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 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 intermount-
able with all existing Miniature Cylindrical Series connectors
except for the threaded coupling PC Series.
