LJT Fail Safe 88-5388/91-5388
(MS27661)
Lanyard Release Plug
Amphenol LJT Breakaway Fail Safe Connectors provide
unequaled performance in environments requiring
instant disengagement.
Designed to provide quick disconnect of a connector plug and re-
ceptacle with an axial pull on the lanyard, the “Breakaway” Fail Safe
connector family offers a wide range of electrical and mechanical
features:
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.
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.
