The Telemecanique / Square D XCKP2902N12 is a compact severe-duty limit switch with NEMA 1/2/4/6/6P/12/13 and IP66/IP67 enclosure. Rated 240 VAC 10 A and 250 VDC 0.27 A, the contacts handle motor starters, solenoid valves, or pilot relays within that load envelope. The 2NC contact configuration (two normally-closed) is typical for safety circuits where a broken wire or actuator release opens the loop and stops the machine. Actuation is via a steel top roller plunger — a straight vertical plunger with a roller that tracks cam profiles or machine slides. Snap-action operation gives a crisp, bounce-free contact transfer at the trip point, which matters for PLC input timing.
The XCKP2902N12 is a standard-stocked line item that can be quoted to order. No cross-reference or second-source is recorded.
Approvals and standards
UL and CSA listed, so the switch is accepted for North American panel builds without additional agency review. It also complies with EN/IEC 60204-1 (machine safety – electrical equipment) and EN/IEC 60947-5-1 (control circuit devices – switching elements), covering European machine-directive requirements.
Connection is through a 1/2-inch NPT conduit entry with screw-clamp terminals. Operating temperature range is -13 to 158 °F.
