Features, Specifications

SJT connectors combine unique design features of the
scoop-proof LJT series within standard mounting dimensions of JT types.
Available in a wide range of shell sizes, finishes, insert arrangements
and accessories.
Standard connectors use aluminum shells. Standard plating on shell components is
cadmium over nickel with many optional finishes available. A dependable 5-key/keyway shell
polarization with bayonet-lock coupling is incorporated to aid and assure positive mating.
The insert material is a high-temperature, rigid dielectric polymer providing excellent electrical characteristics.
A fluorinated silicone interfacial seal is featured on the mating face of the pin inserts, assuring complete
electrical isolation of the pins when connector halves are mated. Contrasting letter or number
designations are used on the insert faces. A main joint gasket is installed in the receptacles
SJT features:
for moisture sealing between connector halves.
• 100% scoop-proof design – basic
MIL-DTL-38999 Series I* lengths
Serrated and threaded shells, with a moisture sealing pilot for back shells, accept a wide
range of accessories.
Hermetic seal receptacles are available in carbon steel or stainless steel shells.

A plug with a given rotation letter will mate with a receptacle with the
same rotation letter. The AB angle for a given connector is the same
whether it contains pins or sockets. Inserts are not rotated in
conjunction with the master key/keyway.
AB angles shown are viewed from the front face of the connector. A
recep acle is shown below. The angles for the plug are exactly the
t
same, except the direction of rotation is opposite of that shown for the
receptacle.
