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 392F 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 302F. The JTN or LJTN type connectors are available for N O resistance 2 4 provided they are mated, and un-grommeted rear faces are suitably protected. For complete listing and definition of connector types, shell styles and service classes, see How to Order, pages 62 & 63. For information on Fail-Safe Lanyard Release style plugs, see pages 9496. Where proof of high reliability and lot control is required, MS approved MIL-DTL-38999 equivalents to most propri etary JT and LJT connectors are available. * MIL-DTL-38999 Series I supersedes MIL-C-38999 Series I.
