What this part is, in plain language
The XCKT2110N12 is a Schneider Electric XCKT-series plunger-actuated limit switch with a plastic housing, one normally-open and one normally-normally-closed contact set (1NO/1NC), and screw-clamp terminations for panel wiring.
Ratings that actually decide the fit
The DC rating of 0.27 A at 250 V is the ceiling for the NC/NO set in DC duty; if the application drives a DC coil or a DC indicator lamp at higher current, this is the limit that governs the choice, not the AC headline. Operating range spans -13 °F to 158 °F, so the switch is rated for unheated industrial cabinets and most indoor cell environments but is not specified for sub-freezing outdoor service beyond the IP66/IP67 enclosure capability. Operating force tops out at 15 N, with linear plunger travel from the top actuator position; shock and vibration resistance are flagged on the spec sheet, which matters when the switch is mounted on a stamping press, a vibrating conveyor, or any line subject to mechanical shock beyond steady-state motion.
Mounting geometry and panel integration
Surface mount with two mounting holes spaced 40 mm center-to-center (1.57 in hole diameter) — the body footprint of 2.28 in wide by 2 in high by 1.18 in deep leaves a low-profile package that drops onto a flat bracket or machine frame without a DIN-rail adapter. Overall width including actuator projection is 3.12 in; the top-mounted plunger extends 0.39 in, so the cam or dog that trips the switch must clear that height with margin for overtravel per IEC 60947-5-1. Wiring is via screw-clamp terminals, which accept ferrule-terminated stranded conductors without a special tool and keep field replacement a straight swap when an MRO tech opens the cover.
Approvals and standards coverage
The XCKT2110N12 is UL Listed to UL 508, certified to CSA C22.2 No.14, and carries EN 60204-1 / IEC 60204-1 (electrical equipment of machines) plus IEC 60947-5-1 / EN 60947-5-1 (low-voltage switchgear control-circuit devices), so it slots into a control panel destined for North American, Canadian, and CE-marked European machinery without an additional submittal review on the switch itself. CCC listing covers China-market machinery builds; the IEC/EN pair covers the EU/UKCA acceptance path.
