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 for moisture sealing between connector halves.
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.
Rear insertable/rear release crimp contacts are standard in SJT connectors. Power contacts are available in sizes 10, 12, 16, 20, 22M and 22D. All socket contacts are probe proof. Standard contact plating is 50 mµ minimum gold. Coaxial contacts are available in sizes 8, 12 and 16 to accommodate a wide range of coaxial cables. Size 8 and 12 Twinax contacts are also available.
Special adaptations of the SJT are available for hermetic and high-temperature applications. The SJTS high-temperature connector is rated at 392°F. SJT hermetic receptacles are can be viewed here.
Special types are available, such as connectors less contacts and circular rack and panel connectors with solderless wrap contacts. For further information on special application requirements, contact Amphenol Aerospace.
