DC3 20-Pin IDC Socket Connector (Pack of 5)

An IDC (insulation displacement connector) socket terminates every conductor of a ribbon cable simultaneously under mechanical pressure, piercing each wire's insulation to make contact rather than requiring individual wires to be stripped, crimped, or soldered one at a time. That all-at-once termination is exactly why ribbon cable and IDC connectors are paired so often in automotive and industrial wiring harnesses - assembling a 20-conductor cable connection takes one press operation instead of 20 individual terminations.

Nickel-plated brass contacts resist corrosion at the connection points, and a 3A current rating per contact covers genuine signal and low-power wiring duty. UL94V-0 flammability rating and a -40°C to 105°C operating range suit both automotive and general industrial environments where a connector needs to hold up reliably outside a controlled indoor setting. Selling in a 5-pack covers a small production run or multiple harness builds from one purchase.

Common uses are automotive wiring harness connectors terminating multi-conductor ribbon or flat cable, industrial control panel wiring needing quick multi-pin termination, and general electronics projects using ribbon cable for multi-signal connections.
