Combo-D series connectors permit mixed contact com-
binations of power, shielded, air, high voltage and signal
contacts within the same connector body. Twenty-two
connector variants are offered in six standard shell sizes.
Three performance levels of Combo-D series connec-
tors are offered: professional, industrial and military. CBD
series connectors are quality connectors recommended
for use in sheltered, non-corrosive indoor and outdoor
environments having normal ventilation, but without tem-
perature or humidity controls. Signal contacts are offered
with open entry professional level or PosiBand closed
entry industrial level signal contacts. CBD series connec-
tors meet performance requirements of I.E.C. 807-2,
Performance Level One or Two. CBM series connectors
are military quality connectors recommended for use in
sheltered, mildly corrosive environments having a wide
range of temperature, pressure and humidity changes.
CBM series connectors will meet the applicable perform-
ance requirements of D.E.S.C. 85039.
Combo-D series connectors utilize precision machined
signal contacts. Connector variants are available with
contact terminations for solder and straight and right
angle (90°) printed board mount terminations featuring a
choice of inch or metric printed board footprints.
Power, shielded and high voltage contacts are remov-
able, having solder and straight and right angle (90°)
printed board mount terminations. Power and shielded
contacts are available with crimp terminations. Air contact
options are also available, see page 80 for details.
For low level shielding requirements, ferrite inductors
may be attached to both signal and power contacts of
connectors having contact terminations which are
straight or right angle (90°) for printed board mounting
applications. For additional information contact Technical
Sales.
The female power contacts feature the Large Surface
Area (L.S.A.) closed entry contact design which pro-
vides maximum mating surfaces between male and
female contacts and reduced contact resistance during
operation.
A wide assortment of printed board mounting hard-
ware, cable support hoods, and locking systems is avail-
able from stock.
A blind mating system is available for applications
requiring connector coupling in recessed areas or mobile
power coupling systems.
Straight and right angle (90°) PCB mount thermocou-
ple contacts are available, please contact Technical Sales
for details.
