MIL-DTL-38999 Series II connectors
feature a bayonet coupling mechanism with lower profile
design and rear-removable crimp contact retention system.
These connectors were designed for military
and commercial applications where the prime requirements
are lower profile and lighter weight.
Reduction of both size and weight were
the use of thinner shell walls and length restrictions.
design restrictions reduced the RFI attenuation characteristics
and the “scoop” protection, while yielding
an excellent general
purpose, lightweight connector. Compared to Series
Series II connectors achieve up to 20% reduction in
pair length, up to 39% reduction in outside diameter
up to 40% reduction in weight (128 pin mated pair).
This family of connectors is offered
in six receptacle-mounting
styles. They include square flange receptacles, for
and rear panel (wall) mounting; square flange receptacles,
for both front and rear panel (box) mounting; square
receptacle with extended grommet, for front of panel
mounting; and jam nut receptacles which incorporate
“ O” ring seals, designed for rear panel “D” hole mounting.
Plugs are available in two designs,
with and without RFI
