Double Density D - .075" Contact Spacing

2D

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

thus accommodate up to 100 contacts instead of 50.

This double contact density is achieved by using

contacts on .075 (1.91) centers, in the positive con-

tact alignment design. In this design contact

contacts are recessed in the insulator and the more

reversal of positions, and the chamfered-entry of the

sockets, assures positive mating even under severe

misalignment conditions. The contacts are retained

in the monobloc insulator by a resilient internal

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.

Contacts are crimp removable type.

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.
