Amphenol SJT
Specifications, Alternate Rotations
Amphenol® SJT connectors combine unique design fea tures 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Specications– PAN6433-2, LN29729, VG96912
Components
Shell components are aluminum. Standard plating on shell components is cadmium over
nickel with many optional nishes 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 uorinated 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 gas ket 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 accessories.
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 con nectors. 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-aerospace.com/
contacts.asp
Optional Features
Special adaptations of the SJT are available for hermetic and high temperature applications. The SJTS high temperature
con nector 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
informa tion on special application requirements, contact Sidney N.Y.

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 tacle is shown at right. The angles for the plug are exactly the
same, except the direction of rotation is opposite of that shown for the
receptacle.
