Double Density D - .075" Contact Spacing
2D
The Double Density D is a rectangular connector in
the popular D Subminiature shell configuratoin fea-
turing 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™ con- not damage the internal shoulder in the insulartor.
tacts are recessed in the insulator and the more Contacts are crimp removable type.
rugged Centisocket™ contacts are exposed. This The Double Density D connector is available in the
reversal of positions, and the chamfered-entry of five popular shell and insert sizes accommodating
the sockets, assures positive mating even under up to 100 contacts. These connnectors mate exclu-
servere misalignment conditions. The contacts are sively with other Double Density D connectors. A
retained in the monobloc insulator by a resilient wide range of accessories can be used, including
internal shoulder that snaps into a locking groove in junction shells, potting cups, switching shells, guide
the contact. The chamfered front of the contact will pin plates, and dust caps.
1. STANDARD D HARDWARE-
1 Including full range of D Subminiature accessories
2. ONE PIECE TYPE INSULATOR-
glass-filled nylon material
2 3. CONTACT RETENTION-
thermoplastic internal shoulder snaps into a locking groove in the contact.
Retention Force: 8 lbs. min. initially, 4 lbs. min. after 10 cycle.
3 4. TWIST PIN CONTACTS-
seven outer wiping surfaces assure electrical continuity even under severe
4 shock and vibration
5. POSTIVE CONTACT ALIGNMENT-
flexible pin is recessed in insulator cavity and rugged socket is exposed
5 6. GUIDE-IN KEYS AND KEYWAYS-
assure alignment during mating and prevent scooping
