Square D XCKD2110N12 Limit Switch, 240VAC 3A, NEMA 4X/6P

The Square D XCKD2110N12 is a compact, modular general duty limit switch from the Telemecanique XCKD family. It's built for position sensing in industrial environments where you need a reliable snap-action contact block and a sealed metal body. Contact rating is 240 VAC 3 A and 250 VDC 0.27 A — that's the switching capacity, not the continuous carry. For a 24 VDC control circuit that's plenty of headroom; for a 120 VAC pilot duty loop it handles most solenoid and relay loads. The 1NO-1NC configuration gives you one form-C equivalent for both status and safety feedback. Enclosure is NEMA 4X/6P/12/13 and IP66/IP67, so the switch body and plunger seal handle washdown, hose-down, and temporary submersion. The zamak metal body resists corrosion better than painted steel in wet or mildly corrosive atmospheres. Actuator is a metal end plunger with spring-return snap action. Actuation speed is 0.5 m/s — fast enough for cam-driven or slide-by actuation on conveyors or transfer lines. The 1/2 inch NPT conduit entry mates to standard rigid or flexible conduit without adapters. Approvals include UL 508, CSA C22.2, CE, and CCC — covers North American and European industrial control panels, plus China market entry. Also compliant with EN/IEC 60947-5-1 (control circuit devices) and EN/IEC 60204-1 (machinery safety).
