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.

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

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 cou-
pling nut spring, and epoxy inserts/fluorinated sili-
cone grommet combination. Standard temperature
capability for both solder and crimp is 302°F.
