The C81/C91 series standard dual beam wire wrap edge-grip sockets feature dual beam edge-grip contacts that provide high retention with positive wiping action. A removable cover provides a lower profile. Side-to-side stackable.
The C81/C91 series provides dual‑beam, edge‑grip contacts that give high retention with a positive wiping action. A removable cover lowers the profile and the sockets are side‑to‑side stackable, making them suitable for dense PCB layouts. Various plating options (Nickel, Tin, Tin/Lead, Gold) are offered to meet different reliability and solderability requirements.
Technical specifications include a contact current rating of 1.5 A, 20 mΩ initial contact resistance, and 100 MΩ insulation resistance at 500 VDC. The body is made of black UL 94V‑0 glass‑filled 4/6 nylon, and the contacts are Grade A phosphor bronze alloy, 1/2 hard. Recommended PCB hole size is .046 + .002 in. Detailed dimensions for each pin count are provided in the data sheet.
