A field-proven, highly reliable Centipin™/Centisocket™ retained in the monobloc insulator by a resilient wide range of accessories can be used, including contacts on .075 (1.91) centers, in the positive internal shoulder that snaps into a locking groove in junction shells, potting cups, switching shells, guide contact alignment design. In this design contact 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.
