Aerospace
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superseded by MIL-DTL-38999.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.
Features & Benefits
• Lightweight, Space Saving Design
• Contact Protection - 100% scoop-proof LJT design prevents
bent pins and short circuits dur ing mating
• Quick Positive Coupling - 3 point bayonet lock system
• Mismating Eliminated - with 5 key/keyway design
• Error Proof Alternate Positioning - insured by dierent key/
keyway locations
• EMI Shielding - grounding ngers standard in LJT Series;
optional in JT Series
• Nine Shell Sizes and a Variety of Shell Styles
• Contact Options - size 8, 10, 12, 16, 20, 22M and 22D Crimp,
Solder, PCB, Wire wrap, Coax, Twinax, Triax, Thermocouple,
Fiber Optic and Fil ter
• Fixed Solder Contacts - Amphenol MIL-DTL-38999 Series I
LJT and II JT, are available in solder versions as both
Commercial and Military qualied to MIL-DTL-27599
• Hermetic - air leakage limited to 1 X 10-7 cm3 per second
optional
• “Breakaway” Lanyard Release Style - available in LJT plugs.
Provides quick disconnect of the connector plug and receptacle
with axial pull on the lanyard. See pages 94-96.
• Inventory Support Commonality - uses stan dard
MIL-DTL-38999 contacts, insert arrangements and
application tools.
• RoHS Compliant Product Available -
Consult Amphenol Aerospace Operations.
Where proof of high reliability and lot control is required, MS approved
equivalents to most propri etary JT and LJT connectors are available.
* MIL-DTL-38999 Series I supersedes MIL-C-38999 Series I.
MIL-DTL-38999 Series II supersedes MIL-C-38999 Series II.

Amphenol
AerospaceSeries I, LJT Breakaway Fail Safe
Quick-Disconnect with Axial Pull of Lanyard
Amphenol LJT Breakaway Fail Safe Connectors provide
unequaled performance in environments requiring
instant disengagement.
Designed to provide quick disconnect of a connector plug and
receptacle with an axial pull on the lanyard, the “Breakaway”
Fail Safe connector family offers a wide range of electrical and
mechanical features:
• Instant decoupling and damage free separation
• Completely intermateable with standard LJT receptacles
• Inventory support commonality through the use of standard
insert arrangements and contacts
Breakaway un-mating is initiated by applying a pull force to the lan-
yard which causes the operating sleeve on the plug to move away
from the receptacle. Coupling segments on the plug then move
away from the mating receptacle while expanding, thus releasing the
receptacle. After completion of the un-mating sequence, spring com-
pression returns the sleeve and segments to their original positions.
Un-mating of the plug may also be accomplished by normal rotation
of the coupling ring without aecting the breakaway capability.
* To complete order number see page 95.

The LJT Breakaway Fail Safe connector features which
provide EMI EMP shielding in excess of MIL-DTL-38999
Series I requirements:
• Solid metal-to-metal coupling
• EMI grounding ngers
• Conductive nishes
Contact Amphenol Aerospace for more information on breakaway,
quick-disconnect connectors. Other Amphenol cylindrical families
(MIL-DTL-38999 Series III, MIL-DTL-26482, MIL-DTL-83723) also
oer breakaway quick-disconnect connectors.
In addition to standard Breakaway connectors,
Amphenol also manufactures custom breakaway
connectors including those with:
• Increased pull-force capability
• Custom lanyard lengths and backshells
• Low force separation capabilities
• Low insertion/separation force contacts
• Non-cadmium nishes
• Custom JT Series Breakaway designs have
been developed for special applications;
however the LJT Series is
recommended over the JT Series for the
quick-disconnect breakaway style.
