Amphenol SJT
Specifications, Alternate Rotations
Amphenol
of the scoop-proof LJT series within standard mount ing
dimensions of JT types. Available in a wide range of shell
sizes, finishes, insert arrangements and accessories,
the SJT features:
• 100% scoop-proof design – basic MIL-DTL-38999 Series I* lengths
• Standard mounting dimensions – MIL-DTL-38999, Series III** dimensions
• Compliance with European Specifications – PAN6433-2, LN29729, VG96912
Components
Shell components are aluminum. Standard plating on shell components is cadmium over
nickel with many optional finishes available. Hermetic seal receptacles are available in
carbon steel or stainless steel shells. Dependable 5 key/keyway shell polarization with
bayonet lock coupling is incorporated to aid and assure positive mating. Insert material is a
high temperature, rigid dielectric polymer providing excellent electrical characteristics.
Contrasting letter or number designations are used on insert faces. A fluorinated silicone
interfacial seal is featured on the mating face of pin inserts, assuring complete electrical
isolation of pins when connector halves are mated. In addition, a main joint gasket is
installed in the receptacles for moisture sealing between connector halves. Serrated and
threaded shells with moisture sealing pilot for back shells accept a wide range of accesso-
ries.
Contacts
Standard contact plating is 50 micro inches minimum gold. Power contacts are available in sizes 10, 12, 16, 20, 22, 22M and
22D. Size 8 and 12 Twinax contacts are also available. Concentric Twinax contact information is available in Amphenol
brochure 12-130. All socket contacts are probe proof. Rear insertable/rear release crimp contacts are standard in SJT
connectors. High density insert patterns are available. Coaxial contacts are available in sizes 8, 12 and 16 to accommodate a
wide range of coaxial cables. For complete information see Coaxial Contact catalog 12-130 online at www.amphenol-aero-
space.com/contacts.asp
Optional Features
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 described on pages 83 and 84.
Specials
Special types are available, such as connectors less contacts, and circular rack and panel connectors with solderless
wrap contacts. A complete listing of connector types, shell styles and service classes appears on page 76, How to
Order. For further information on special application requirements, contact Sidney N.Y.
