Mixed Density Dual Port Series connectors utilize one standard den-
sity connector and one high density connector, vertically stacked and
assembled into a single connector unit. This single connector unit per-
mits saving of panel and printed board space and decreases final
assembly costs.
Mixed 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 the normal density over a high den-
sity connector: 9 over 15, 15 over 26, 25 over 44 and 37 over 62.
Connector genders can be mixed, i.e., one male and one female con-
nector within one Mixed Density Dual Port assembly. The two connec-
tors may be spaced apart to three standard dimensional spacings. The
connector may also be partially populated with contacts which are
installed in the connector 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.
Mixed Density Dual Port Series connectors comply with the dimen-
sional requirements of MIL-DTL-24308.
