Amphenol® JT/LJT
high reliability and high contact density
with maximum weight and space savings
Amphenol® LJT and JT Series subminiature cylindrical
connectors are qualified to MIL-DTL-38999*, Series I and
II respectively. These connectors were developed to meet
the needs of the aerospace industries, and provided the
impetus for development of the MIL-C-38999 specifications, which recently were superseded by MIL-DTL-38999.
Meeting or exceeding MIL-DTL-38999 requirements, Amphenol® JT/LJT connectors feature:
• Lightweight, Space Saving Design
• Contact Protection - 100% scoop-proof LJT design
prevents bent pins and short circuits during mating
• Quick Positive Coupling - 3 point bayonet lock system
• Mismating Eliminated - with 5 key/keyway design
• Error Proof Alternate Positioning - insured by different
key/keyway locations
• EMI Shielding - grounding fingers 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 Filter
• Fixed Solder Contacts - per MIL-C-27599 (see page 52
and Amphenol Product Data Sheet 158)
• 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
38-41.
• Inventory Support Commonality - uses standard MILDTL-38999 contacts, insert arrangements and application tools.
• RoHS Compliant Product Available pheno

Shell components are impact extruded or machined
bar stock aluminum. Standard plating on shell components is cadmium over nickel. Many finishes are
optional (see “Specifications” page 3). Hermetic seal
receptacles are available in carbon steel or stainless steel shells. Dependable 5 key/keyway polarization with bayonet lock coupling is incorporated
to aid and assure positive mating.
Insert material is a rigid dielectric with excellent electrical characteristics, providing durable protection
for molded-in solder type contacts. Contrasting letter or number designations are used on insert faces.
A fluorinated silicone interfacial seal wafer is featured 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, thermocouple, fiber 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 coupling nut spring, and epoxy inserts/fluorinated silicone 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 ungrommeted rear faces are suitably protected.
For complete listing and definition of connector
types, shell styles and service classes, see How to
Order, page 53. For information on Fail-Safe Lanyard Release style plugs see pages 38-41.

A plug with a given rotation letter will mate with a receptacle
with the same rotation letter. The AB angle for a given
connector is the same whether it contains pins or sockets.
Only the master key/keyway rotates in the shell, and the
insert always remains in the same position relative to the
minor keys.

A plug with a given rotation letter will mate with a receptacle
with the same rotation letter. The AB angle for a given
connector is the same whether it contains pins or sockets.
Only the master key/keyway rotates in the shell, and the
insert always remains in the same position relative to the
minor keys.

LJT Breakaway Fail Safe
quick-disconnect with an axial pull
of lanyard
Amphenol LJT Breakaway Fail Safe Connectors provide
unequalled 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 lanyard 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 compression 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.
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 fingers
• Conductive finishes
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 finishes
• 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.
Contact Amphenol Aerospace for more information on breakaway, quickdisconnect connectors. Other Amphenol cylindrical families (MIL-DTL-38999
Series III, MIL-C-26482, MIL-C-83723) also offer breakaway quick-disconnect
connectors.

JT/LJT – accessories
universal “header assembly” for flex print or
PC board mounting
Mounts to all MIL-DTL-38999 and
MIL-C-26482 Connectors
The use of connectors with printed circuit
termination is rapidly gaining popularity due
to the rise of high volume, vapor phase or
wave solder manufacturing processes. Termination of this style of connector to flex print
or a printed circuit board represents a major
cost in the manufacturing process for users.
When adding flex or printed circuit board
assemblies to an expensive filter or filter/
transient protection connector, the total cost
of a failed solder joint, a bent pin, or an unanticipated electrical failure becomes prohibitive. The universal header assembly from Amphenol will provide for easy separation of the connector from
the board on these occasions.
Headers provide easy
separation of the
connector from the PC
board.
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 flex 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 modifications are recommended, but are not necessary. The header
assembly can be attached to connectors with standard flange placement or
directly to the circuit board. The ideal application would involve either a single
flange moved all the way to the rear of the connector or a double flange. Cinch
nuts can be installed in either flange to allow easier mounting to the panel or
the header assembly. The forward flange would mount the connector to the
panel; the rear flange 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 MILDTL-38999 or MIL-C-26482 connectors without special alterations. They are of
similar dimension as the flange of the mounting connector and would be approximately .185 inches (4.70 mm) thick.
Incorporates a Shorter Pin/Socket Contact
The heart of the header assembly is a short pin/socket contact. The tail of the
contact would accommodate standard through-hole diameters and thickness
of the flex or printed circuit board materials. The socket is imbedded in the
molded material, making electrical engagement with the printed circuit tail of
the connector.
48

JT/LJT — solder
contact connectors
Amphenol® LJT and JT Series solder contact connectors
are qualified to Series I and II respectively, of MIL-C-27599.
These connectors use a rigid, hard dielectric insert, which
is molded around the pin and socket contacts. This permits
a higher degree of pressurization across an interface, of up
to 1x10-3 cc/sec. Contact positional tolerances are also
considerably reduced, with less chance of pin bending.
Shell styles similar to MIL-DTL-38999 crimp connectors are
available along with a large variety of contact sizes and
insert patterns.
A complete line of accessories is also available.
