The Double Density D is a rectangular connector in
the popular D Subminiature shell configuration
featuring double the contact density in the same
insert area. The Double Density D connector can

The Double Density D connector is available in the
five popular shell and insert sizes accommodating up
to 100 contacts. These connectors mate exclusively
with other Double Density D connectors. A wide
range of accessories can be used, including junction
shells, potting cups, switching shells, guide pin
plates, and dust caps.

misalignment conditions. The contacts are retained
This double contact density is achieved by using
field-proven, highly reliable CentipinTM/CentisocketTM
contacts on .075 (1.91) centers, in the positive con-
tact alignment design. In this design contact

shoulder that snaps into a locking groove in the con-
tact. The chamfered front of the contact will not
damage the internal shoulder in the insulator.
