PXNA (non-environmental, Type IV) and
DPXNE (environmental, Types II and III) rack and
p
anel connectors are designed to meet or exceed
t
he requirements of MIL-C-81659, Revision B. They
a
re used in military and aerospace applications and
computer periphery equipment requirements, and
a
re designed to operate in temperatures ranging
f
rom - 65˚C to + 125˚C. DPXNA/NE connectors
are available in single, 2, 3, and 4 gang configurations
w
ith a total of 12 contact arrangements
a
ccommodation contact sizes 12, 16, 20 and 22,
and combination standard and coaxial contacts.
C
ontact 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.
