Components
Shell components are impact extruded or machined
bar stock aluminum. Standard plating on shell com-
ponents is cadmium over nickel. Many finishes are
optional (see “Specifications” page 3). Hermetic seal
receptacles are available in carbon steel or stain-
less steel shells. Dependable 5 key/keyway polar-
ization with bayonet lock coupling is incorporated
to aid and assure positive mating.

Insert material is a rigid dielectric with excellent elec-
trical characteristics, providing durable protection
for molded-in solder type contacts. Contrasting let-
ter or number designations are used on insert faces.

A fluorinated silicone interfacial seal wafer is fea-
tured 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.

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, ther-
mocouple, fiber optic, coaxial, triaxial and twinax
contact options.
