FEATURES:
Designed for mobile, transportable,
and semi-permanent military
communications facilities
(telephone, telegraph, teletype,
radio, etc.)
High-reliability Hermaphrocon
connectors are designed for speedy,
foolproof interconnections under
extreme field conditions, are
impossible to mismate, even in the
dark
Hermaphrocon plugs mate
interchangeably with both
receptacles and plugs, permitting
connection of either cable end to
any other cable end of distribution
box
Redundant Hermaphrocon design
provides 104 contacts for 52 cable
conductors (52 pairs) assures circuit
continuity with up to 50% contact
damage (jumpers linking redundant
contact pairs are welded for
reliability)
Rugged, waterproof Hermaphrocon
connectors resist wear and damage
caused by dragging on the ground
or through water, even without
covers
