Double Density D - .075 Contact Spacing 2D The Double Density D is a rectangular connector in positions are reversed the flexible Centipin con- not damage the internal shoulder in the insulartor. the popular D Subminiature shell configuratoin fea- tacts are recessed in the insulator and the more Contacts are crimp removable type. turing double the contact density in the same insert rugged Centisocket contacts are exposed. This The Double Density D connector is available in the area. The Double Density D connector can thus reversal of positions, and the chamfered-entry of five popular shell and insert sizes accommodating accommodate up to 100 contacts instead of 50. 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 This double contact density is achieved by using retained in the monobloc insulator by a resilient wide range of accessories can be used, including field-proven, highly reliable Centipin/Centisocket internal shoulder that snaps into a locking groove in junction shells, potting cups, switching shells, guide contacts on .075 (1.91) centers, in the positive the contact.

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 6 How to Order 2D E 19 S 2D A F 31 P BR * * * * SERIES SHELL SIZE FLOAT MOUNTS CONTACT ARRANGEMENT CONTACT TYPE TERMINATION MODIFICATION NOTE: Connectors may be ordered less contacts by adding the mod calloutF at enc of number.
