Pin and Sleeve Connectors in San Diego
ESU Sells New, Used & Recycled Transformers and Electrical Supplies including Pin and Sleeve Connectors for the San Diego, Orange County, Riverside and LA areas!
One of the specialty product lines we often supply is pin and sleeve connectors—a rugged style of industrial connector used for power circuits. Pin-and-sleeve devices come in several basic types: plugs (male cord-end), connectors (female cord-end), inlets (male panel or back box mounted), and receptacles (female panel mounted). NEMA+1 These devices are designed to interlock and seal, resisting accidental disconnection under load and protecting against moisture, dust, and harsh environments. NEMA Because of their durability and flexibility in amperage and configuration, they’re often used in industrial, commercial, or heavy-duty installations—but they also turn up in specialized residential and contractor work. With our experience, ESU can help you choose the right pin and sleeve version, match it to your existing equipment, and make sure your system is safe and code-compliant.
