High Density Dual Port Series connectors utilize two high density
connectors vertically stacked and assembled into a single connector
unit, which permits saving of panel and printed board space, and
decreases final assembly costs.
High Density Dual Port Series connectors are professional quality
connectors
recommended
for
use
in
sheltered,
non-
corrosive indoor and outdoor environments having normal ventilation.
Connector contact variants are 15, 26, 44 and 62. Connector gen-
ders can be mixed, i.e., one male and one female connector within one
High Density Dual Port assembly. The two connectors may be spaced
apart to three standard dimensional spacings. The connector may also
be partially populated with contacts which are installed in the connec-
tor body to customer selected contact positions.
Mounting angle brackets can be ordered riveted to the connector by
specifying R2, R6, R7 or R8 options. Locking systems are available uti-
lizing 4-40 threaded jackscrew systems, polarized or non-polarized, or
with a quick release Vibration Lock System for either front or rear panel
mounted connectors.
High Density Dual Port Series connectors comply with the dimen-
sional requirements of MIL-DTL-24308.
