DPXNA/DPXNE
Cannon's DPXNA (non-environmental, Type IV) and
DPXNE (environmental, Types II and III) rack and
panel connectors are designed to meet or exceed
the requirements of MIL-C-81659, Revision B. They
are used in military and aerospace applications and
computer periphery equipment requirements, and
are designed to operate in temperatures ranging
from - 65˚C to + 125˚C. DPXNA/NE connectors
are available in single, 2, 3, and 4 gang config-
urations, with a total of 12 contact arrangements
accommodation contact sizes 12, 16, 20 and 22,
and combination standard and coaxial contacts.
Contact retention of these crimp snap-in contacts is
provided by the LITTLE CAESAR® rear release
contact retention assembly. Environmental sealing
is accomplished by wire sealing grommets and
interfacial seals.
