Amphenol® LJT and JT Series subminiature cylindrical
connectors are qualied to MIL-DTL-38999*, Series I
and II respectively. These con nectors were developed
to meet the needs of the aerospace industry, and
provided the impetus for development of the
MIL-C-38999 specications, which has been
superseded by MIL-DTL-38999. Meeting or exceeding
MIL-DTL-38999 requirements, Amphenol® JT/LJT
connectors feature:
MIL-DTL-38999, Series II JT
MIL-DTL-38999, Series I LJT
Components
Shell components are impact extruded or machined bar stock
aluminum. Standard plating on shell com ponents is cadmium over
nickel. Many nishes are optional (see “Specications” page 19).
Hermetic seal receptacles are available in carbon steel or stainless
steel shells. Dependable 5 key/keyway polarization with bayonet lock
coupling is incorpo rated to aid and assure positive mating.
Insert material is a rigid dielectric with excellent electrical character-
istics, providing durable protec tion for molded-in solder type contacts.
Contrasting letter or number designations are used on insert faces.
A uorinated 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 exibility is built into the JT/LJT Series, with a mini-
mum 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, ber 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 cou pling nut
spring, and epoxy inserts/uorinated sili cone grommet combination.
Standard temperature capability for both solder and crimp is 302°F.
The JTN or LJTN type connectors are available for N2O4resistance
provided they are mated, and un-grommeted rear faces are
suitably protected.
For complete listing and denition 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 94–96.
