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were superseded by MIL-DTL-38999.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 48 and Amphenol Product Data Sheet 158)
• Hermetic - air leakage limited to 1 X 10-7 cm3 per
second optional
• Inventory Support Commonality - uses
standard MIL-C-38999 contacts, insert arrangements and application tools.
Amphenol® JT Connector
Where proof of high reliability and lot control is required,
MS approved equivalents to most proprietary JT and LJT
connectors are available.

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.

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.

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.

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.
Cylindrical Configuration
• 3 PCB stickout dimensions are available.
• Size 22D contacts use .175 thick headers
• Size 16 to 20 contacts use .195 thick
headers
• Consult Amphenol, Sidney NY for additional
configurations.
• Headers for cylindrical connectors accommodate up to 128 pins. See pages 4-11 for
JT/LJT mating connector contact layouts.
Also see catalog 12-092 for MIL-DTL-38999,
Series III mating contact layouts and catalog
12-070 for MIL-C-26482 mating contact
layouts.
Mounting to Rectangular ARINC
Connectors
• Headers for ARINC connector arrangements
accommodate up to 150 pins
• Consult Amphenol, Sidney, NY for ARINC
configurations and detailed dimensions.
Materials
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.
44
• Body is molded from Torlon or PPS
(Polyphenylene Sulfide)
• Electrical engagement areas of the header
contact are plated with .00003 inches
minimum of gold over .00005 inches
minimum of nickel.

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.

FILTER/TRANSIENT PROTECTION
Filter and/or voltage surge arresting devices are integrated into a JT or
an LJT connector to eliminate conventional bulky exterior filtering systems. This unique design reduces weight, space and user testing while
providing system protection from EMI/ EMP. Ask for publication 12-120
or contact Amphenol, Sidney, NY for complete information on Amphe®
nol EMI Filter/Transient Protection Connectors.
AQUACON
Specially designed connectors for underwater and other fluid-immer®
sion applications are available in all Amphenol JT/LJT insert arrangements. Aquacon AJ (immersible JT) or AL (immersible LJT) series connectors offer 1500 psi capability, visual mating indication to assure
proper sealing upon mating, and design flexibility at low cost. Corrosion resistant materials and environment-proof molded cable terminations provide a connector well suited to immersed usage. AJ and AL
Series Aquacon Connectors represent the utmost in general purpose
immersible connectors. Refer to catalog 12-140 for additional data.
FAIL-SAFE BREAKAWAY
®
The Amphenol Fail-Safe Breakaway Connector has been
designed for those special applications needing a quick
disconnect. Many of the JT features have been designed
into the “Fail-Safe,” including five-key polarization, threepoint bayonet lock coupling, standard insert arrangements
and mating interchangeability with JT receptacles. The sixsegment design of the ramp sleeve assures complete
separation, regardless of coupling orientation. If bayonet
pins on the receptacle shell have not been completely
coupled into position, the segments (upon lanyard pull)
will release the entire receptacle without damage. The FailSafe is also available in an LJT configuration. Catalog 12160 provides more detailed information on Fail-Safe
Breakaway Connectors. Also see Fail-Safe Lanyard connectors in MIL-DTL-38999 Series III; consult Amphenol
catalog 12-092.

JT/LJT
specials - ground plane connectors
Amphenol offers MIL-DTL-38999 Series I and II* connectors for data
bus, LAN and coax/triax/twinax transmission lines with conductive
inserts that ground the outer conductor of the coax, triax or twinax
contact to the shell. These connectors are sold “less contacts”. They
will accommodate size 8 coax, triax or twinax contacts or size 12
and 16 coax contacts.
The insert availability chart on pages 4-6 indicate the patterns that
are available in a ground plane version, (see those designated with a
star symbol), and consult how to order page for ordering procedure.
CONNECTORS WITH COAX CONTACTS
For shielded wire applications, coaxial contacts can be incorporated
into MIL-DTL-38999 connectors. Designed-in crimp or solder types
are available to fit various RG and special cables. High performance
coaxial contacts eliminate discontinuities or impedance variations
due to movement of parts under axial load. For further information on
coax contacts ask for catalog 12-130.
CONNECTORS WITH CONCENTRIC TWINAX CONTACTS
The size 8 concentric twinax contact was developed for use in MILSTD-1553 Airborne multiplex data bus applications which require
high performance interconnect characteristics in multi-pin connectors. Ideal for this application need is the high performance Tri-Start
connector with its fully scoop-proof feature of recessed pins. (See
Amphenol catalog 12-092) The concentric twinax contact is
crimp terminable to twisted-shielded cable. Other features
include:
• Provides protection from magnetic and electrostatic interference including nuclear electromagnetic pulse
• Maintains shield integrity through a multi-pin cylindrical
connector and does not require contact polarization within the
insert
• 175°C rated and meets performance levels of MIL-DTL-38999
Series III connectors
• Available in size 8 and 12 contacts
• MIL-C-17/176-00002 cable termination
• Qualified to M39029/90 & /91
• Integral part of the MIL-STD-1760 interconnection system
For further information on concentric twinax contacts, consult
catalog 12-130.
CONNECTORS WITH REDUCED COMPONENT TWINAX (RCT)
CONTACTS
The RCT (Reduced Component Twinax) contact meets MIL-C39029/90 and /91 requirements for intermateability and performance while reducing the number of user-assembled components from seven to three. The inner conductors and outer barrel
of the RCT are each terminated to the cable by a crimp joint, so
no costly assembly soldering operations are required. Features
include:
• Three user assembled components
• Available in size 8 and size 10 contacts
• MIL-C-17/176-00002 cable termination
• For installation in MIL-DTL-38999 Series III connectors
• Termination completed in only two crimping operations
• Inner conductors stripped to common length, eliminating
multiple measurements
For further information on RCT contacts, consult catalog 12-130.
