Combo D^®
Combination D Subminiature connectors are the
fastest growing segment of the D Subminiature
market. ITT Cannon engineering teams, in keeping
pace with the demands of the industry, have devel-
oped the broadest selection of combination D Sub-
miniature available.
We offer the ability to intergrate signal and coax,
high power, and high voltage. You can mix red,
green, and blue video lines with signal and up to 40
amps of power in the same package.
Design variations of the new Combo D connector,
versus other packaging methods, include the proven
ITT Cannon polarized "D" shape to prevent mis-
mating; dense, space-saving packaging; and diverse
mounting options. Choose from a variety of cable
cand printed wiring board selections. Printed wiring
board combos come pre-assembled with fixed con-
tacts eliminating the need to buy several compo-
nets.
This new line of conectors offers you unlimited
design versatility.
Straight and right angle printed wiring board contacts are available in both coax and high power versions.
