Features & Benets
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 “Specications” page 16). 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 elec-
trical characteristics, 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 seal-
ing between connector halves. Both features are also
available for hermetic receptacles.
Contacts
Maximum design exibility 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, 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 definition of connector
types, shell styles and service classes, see How to
Order, page 46. For information on Fail-Safe Lanyard
Release style plugs, see pages 78–80.

Series 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 affecting the breakaway capability.
* To complete order number see page 79.

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
offer 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.

Mounts to all MIL-DTL-38999 and
*MIL-DTL-26482 Connectors
Termination of PC tail connectors to a ex
print or a printed circuit board represents
a major cost in the manufacturing process
for users. When adding ex or printed
circuit board assemblies to an expensive
lter or lter/transient protection connec-
tor, the total cost of a failed solder joint,
a bent pin, or an unanticipated electrical
failure becomes prohibitive. The universal
header assembly from Amphenol provides
for easy separation of the connector from the board on these occasions. The
header assembly is comprised of a short pin/socket contact. The tail end of
the contact is soldered to the through hole of the ex or printed circuit board.
The socket is embedded in the insulator, making electrical contact with the
printed circuit tail of the connector.
Header Assemblies Provide Cost Savings
Incorporation of the header assembly provides the user with time and cost
saving potentials. These header assemblies can be vapor phase or wave
soldered to ex or printed circuit boards prior to the receipt of the EMI/EMP
connector. Headers can be installed to standard connectors, allowing for
electrical testing that would adversely affect the sensitive diodes, MOV’s or
capacitors in the EMI/EMP connectors. Expensive connector assemblies
can be easily removed from and reattached to the header assembly as the
manufacturing process dictates.
Mounting Applications
Shell modications are recommended, but are not necessary. The header
assembly can be attached to connectors with standard ange placement
or directly to the circuit board. The ideal application would involve either
a single ange moved all the way to the rear of the connector or a double
ange. Cinch nuts can be installed in either ange to allow easier mounting
to the panel or the header assembly. The forward ange would mount the
connector to the panel; the rear ange would be used to mount the header
assembly. Various types of captivated or loose attaching screws can be
utilized for unique applications.
Amphenol universal headers are slotted to allow mounting to all series of
MIL-DTL-38999 or MIL-DTL-26482* connectors without special alterations.
They are of similar dimension as the ange of the mounting connector and
are approximately .185 inches (4.70 mm) thick.
* For information on Header Assemblies for MIL-DTL-26482 connector
