Amphenol® LJT and JT Series subminiature cylindrical
connectors are qualified 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 specifications, which has
been superseded by MIL-DTL-38999. Meeting or exceeding
MIL-DTL-38999 requirements, Amphenol® JT/LJT connectors

Features & Benets
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 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.

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 modications 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
consult Amphenol, Sidney NY.
Cylindrical Configuration
• 3 PCB stickout dimensions are available.
• Size 22 contacts use .175 thick headers
• Size 16 to 20 contacts use
.195 thick headers
• Consult Amphenol, Sidney NY for
additional congurations.
• Headers for cylindrical connectors accom-
modate up to 128 pins. For MIL-DTL-38999
insert arrangements chart see pages 4-7
and insert drawings on pages 8-14.
Mounting to Rectangular ARINC
Connectors
• Headers for ARINC connector arrangements
accommodate up to 150 pins
• Consult Amphenol, Sidney, NY for ARINC
congurations and detailed dimensions.
Materials
• Body is molded or machined from FR-4.
• Electrical engagement areas of the header
contact are plated with .00003 inches
minimum of gold over .00005 inches
minimum of nickel.
See drawing of standard header on next page.
Headers provide easy
separation of the
connector from the PC board.

Where 2 or 3 tools are listed for a contact size, only one tool and its die or
positioner are required to crimp the contact. The above crimping tools and
positioners are available from the approved tool manufacturer.
The following data includes information pertaining to the appli-
cation tools which have been established for crimping, inserting,
and removing contacts incorporated in the TV, CTV and MIL-
DTL-38999 Series III connectors. For additional information on
coax, twinax and triax contact tools see High Speed Contact
section of this catalog. All crimping tools included are the “full
cycling” type and when
used as specied in the installation instructions (L-624 and
L-844) covering the TV, CTV and MS series connectors,
will pro vide reliable crimped wire to contact terminations.
There is a possibility of additional crimping tools other
than those included being available at present or in the
future for this specic appli cation.
