Amphenol SJT
Features, Specifications
Amphenol^® 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, 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
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.
Contacts
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; see Coaxial contact information in the High Speed
Contact section of this catalog. Size 8 and 12 Twinax contacts are also available; see Concentric Twinax contact information in the
High Speed Contact section of this catalog.
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 page 88.
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 83, How to Order.

position to know what peak voltage, switching surges, transients, etc., can be expected in a particular circuit.
