Double Density D - .075" Contact Spacing The Double Density D is a rectangular connector in the popular D Subminiature shell configuratoin 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 field-proven, highly reliable Centipin™/Centisocket™ contacts on .075 (1.91) centers, in the positive contact alignment design. In this design contact positions are reversed; the flexible Centipin™ contacts are recessed in the insulator and the more rugged Centisocket™ contacts are exposed. This reversal of positions, and the chamfered-entry of the sockets, assures positive mating even under servere misalignment conditions. The contacts are retained in the monobloc insulator by a resilient internal shoulder that snaps into a locking groove in the contact. The chamfered front of the contact will 2D not damage the internal shoulder in the insulartor. 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 connnectors 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. 1.
