Pin Connectors

Pin Connectors — New & Used

Pin connectors are essential electrical components used to join cables, wires, devices, and circuit boards safely and securely. They come in many forms — including single-pin, multi-pin, modular, circular, and board-mount connectors — facilitating signal, power, or data transmission in wiring harnesses, control panels, equipment, and electronics.

At Surplus Select, we offer a wide selection of new and used OEM pin connectors and electrical connector assemblies, including single-pin plugs, multi-pin housings, circular connectors, board-mount headers, and mating terminals. Surplus pricing helps contractors, maintenance crews, OEMs, and electronics or machinery builders source reliable connectors affordably and maintain or build wiring systems with confidence.

Price Match — We match any authorized distributor on identical in-stock parts, so you can source parts at surplus pricing with distributor-level assurance.

Trade-In Credit — Have quality new surplus items? Trade them in for store credit toward the parts you actually need.

Fast U.S. Shipping — Most orders ship same or next business day from our U.S. warehouse to keep your wiring and control projects on schedule.

Find Your Connector Fast (Search-First)

Search by connector type or part number (e.g., circular 12-pin connector, board-mount header 10 pin, female pin housing 24-way).
No part number? Try specs like “single pin male connector”, “multi-pin circular plug used”, or “pin header 2.54 mm 20-pin”.
Need specific features? Add pin count, connector style (circular, rectangular, board-mount), gender (male/female), locking type, or voltage rating to refine results.
