The Combo-Dual Port connector series offers several
combinations of power and signal contacts within the same
connector assembly. Seventeen different combinations of
power and signal contact stacked assemblies are available
within four standard shell sizes. The connector assembly
can be partially populated with either signal or power con-
tacts installed in the connector bodies to customer selected
contact positions. The stacked connectors may be spaced
apart to two dimensional spacings.
On special order, the right angle (90°) printed board
mount
15 ampere
contacts may be replaced with size 8
power, shielded or high voltage contacts having crimp or
solder cup terminations. Signal contacts remain in dual
port configuration.
Mounting angle brackets can be ordered riveted to the
connector by specifying R2, R6, R7 and R8 options.
Locking systems are available utilizing 4-40 threaded
jackscrew systems, polarized or non-polarized, or with a
quick-release vibration lock system for rear panel mounted
connectors.
Combo-Dual Port series connectors comply with the
dimensional requirements of IEC 807-2 and DESC 85039.
