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 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.
