Insert Arrangements – Series III connectors
use insert patterns and contacts common to Series I,
making for an easy transition from bayonet to triple-lead,
acme-thread, self-locking coupling.
Bottoming – This feature precludes relative
shell-to-shell motion, which may result in ordinary
wear and moisture entrapment.
Lockwiring Eliminated – Self-locking
quick coupling plug
eliminates the need for lockwiring.
Firewall Capability -
Stainless steel shells in both K and S
firewall classes are offered.
Tool – A single, expendable plastic
tool is used
for both insertion and removal of contacts.
Scoop-Proof Design – Recessed
pins in elongated shells
minimize the possibility for contact damage. In a blind
mating application, mating shells cannot “scoop” the
and cause a shorting or bending of contacts.
Socket Insert – Hard dielectric socket
has lead-in chamfers for positive alignment of pins
partially bent within pre-established limits) with
Insert Seal – Raised moisture barriers
around each pin, which mate into lead-in chamfers of
hard face socket insert, provide individual contact
Interfacial seal is never touched by service tools.
Sealing Grommet – Sealing over a wide
range of wire diameters is assured by a triple wire
each cavity at the rear of the connector.
Stability – Rear release crimp contact
system features a stamped beryllium-copper retaining
captivated by molded-in shoulders of each contact cavity
the insulator. A rear-inserted M81969 plastic tool
the tines beyond the shoulder, releasing the contact.
Thread – Metric thread results in
additional wall thickness giving greater strength and
