The Dual Port Series is a utilization of two connectors, vertically
stacked and assembled into a single connector unit, which permits sav-
ing of panel and printed board space. Final assembly costs are
reduced by condensing two assembly movements into one movement.
Dual Port Series connectors are professional quality connectors rec-
ommended for use in sheltered, non-corrosive indoor or outdoor envi-
ronments having normal ventilation, but without temperature or humid-
ity controls.
Connector contact variants are 9, 15, 25, 29, 37 and 50. Connector
genders may be mixed, i.e., one male and one female connector with-
in one Dual Port assembly. The two connectors may be spaced apart
to three standard dimensional spacings to accommodate various
dimensions of discrete hoods or molded hood assemblies. The con-
nector may also be partially populated with contacts which are installed
in the connector body to customer selected contact positions, thereby
reducing connector costs.
Dual Port Series connectors are offered with two printed board con-
tact hole patterns. One pattern is dimensional in inches and the other
pattern is dimensioned in millimeters. These patterns are commonly
known as Inch Footprints and Metric Footprints.
Mounting angle brackets can be ordered riveted to the connector by
specifying R2, R6, R7 or R8 options. These options provide for labor
saving ease of connector mounting to the printed board and also per-
mit rapid jackscrew installation.
Locking systems are available utilizing 4-40 threaded jackscrew sys-
tems, polarized or non-polarized, or with a quick release Vibration Lock
System for either front or rear panel mounted connectors.
Dual Port Series connectors comply with the dimensional and per-
formance requirements of IEC 807-2 Performance Level Two and
dimensional requirements of MIL-DTL-24308. Dual Port Series con-
nectors also meet the interface connection requirements for EIA RS
232 and RS 449, and the CCITT X.24 recommendations.
