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 specifica-  
tions, which recently were superseded by MIL-DTL-38999.  
Meeting or exceeding MIL-DTL-38999 requirements, Am-  
phenol® 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  
Amphenol® JT Connector  
• 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 MIL-  
DTL-38999 contacts, insert arrangements and applica-  
tion tools.

Components  
Shell components are impact extruded or machined  
bar stock aluminum. Standard plating on shell com-  
ponents is cadmium over nickel. Many finishes are  
optional (see “Specifications” page 3). Hermetic seal  
receptacles are available in carbon steel or stain-  
less steel shells. Dependable 5 key/keyway polar-  
ization with bayonet lock coupling is incorporated  
to aid and assure positive mating.

Insert material is a rigid dielectric with excellent elec-  
trical characteristics, providing durable protection  
for molded-in solder type contacts. Contrasting let-  
ter or number designations are used on insert faces.

A fluorinated 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.

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, ther-  
mocouple, fiber optic, coaxial, triaxial and twinax  
contact options.

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.

LJ T Bre akaway 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 recep-  
tacles  
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 capabil-  
ity.  
The LJT Breakaway Fail Safe connector features which provide EMI/EMP shield-  
ing 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, quick-  
disconnect connectors. Other Amphenol cylindrical families (MIL-DTL-38999  
Series III, MIL-C-26482, MIL-C-83723) also offer breakaway quick-disconnect  
connectors.

JT/LJ T acce s s orie s  
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. Ter-  
mination 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 un-  
anticipated electrical failure becomes prohibitive. The universal header as-  
sembly 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 elec-  
trical testing that would adversely affect the sensitive diodes, MOV’s or capaci-  
tors in the EMI/EMP connectors. Expensive connector assemblies can be eas-  
ily removed from and reattached to the header assembly as the manufacturing  
process dictates.  
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 accom-  
modate 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 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 appli-  
cations.  
Mounting to Rectangular ARINC  
Connectors  
Headers for ARINC connector arrange-  
ments accommodate up to 150 pins  
Consult Amphenol, Sidney, NY for ARINC  
configurations and detailed dimensions.  
Amphenol universal headers are slotted to allow mounting to all series of MIL-  
DTL-38999 or MIL-C-26482 connectors without special alterations. They are of  
similar dimension as the flange of the mounting connector and would be ap-  
proximately .185 inches (4.70 mm) thick.  
Materials  
Body is molded from Torlon or PPS  
(Polyphenylene Sulfide)  
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.  
Electrical engagement areas of the header  
contact are plated with .00003 inches  
minimum of gold over .00005 inches  
minimum of nickel.

JT/LJ T —  
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.  
For additional information on Amphenol® LJT/JT solder type  
connectors, ask for Product Data Sheet 158. Contact your  
local sales office or

tors in flat and sculptured styles. Amphenol provides flex termination  
assemblies for printed circuit board attachment through Amphenol  
ACT, Advanced Circuit Technology. Sculptured® Flexible Circuits have  
built-in terminations that eliminate the failures associated with crimped  
or solder-on contacts. They plug into a printed circuit board and create  
a self-locking terminal pad which eliminates the need for an addi-  
tional interconnect to the PCB. They are designed to meet specific  
lengths, current carrying capacities and to fit the precise geometric  
shape of the connector to board package. For more information see  
ACT brochure.
