JT/LJT Amphenol Connectors - the subminiature cylindrical connectors for every application
MIL-DTL-38999 Series I and II
Components
Shell components are
impact extruded or machined bar stock aluminum. Standard plating on shell components is cadmium over nickel. Many finishes are optional. Hermetic seal receptacles are available in carbon
steel or stainless steel shells. Dependable 5 key/keyway polarization with bayonet lock coupling is incorporated to aid and assure positive mating. Insert material is a rigid dielectric with
excellent electrical characteristics, providing durable protection for molded-in solder type contacts. Contrasting letter or number designations are used on insert faces. A fluorinated
silicone interfacial seal wafer is featured on the mating face of "crimp type pin" inserts. This assures complete electrical isolation of pins when connector halves are mated. In addition, a
main joint gasket is installed in the receptacle for moisture sealing between connector halves. Both features are also available for hermetic receptacles.
Contacts
Maximum design flexibility
is built into the JT/LJT Series, with a minimum of 2 to a maximum of 128 circuits per connector in a wide variety of contact arrangements. Contacts are available in sizes 8, 10, 12, 16, 20,
22, 22D and 22M with standard 50 micro inch minimum gold plating (100 micro inches optional).
All socket contacts are probe proof. Crimp type rear removable contacts are featured in JT-R
and LJT-R connectors. Solder termination contacts are also available, as well as PCB, wire wrap, thermocouple, fiber optic, coaxial, triaxial and twinax contact options.
Optional Features
High temperature
capability of 392°F is available only in JTS or LJTS crimp type connectors. High temperature versions feature gold plated contacts, high temperature shell plating, stainless steel coupling
nut spring, and epoxy inserts/fluorinated silicone grommet combination. Standard temperature capability for both solder and crimp is 302°F.
The JTN or LJTN type connectors are available
for N2O4 resistance provided they are mated, and ungrommeted rear faces are suitably protected.
