The XCKMR54D1 is a general duty compact limit switch from the Telemecanique Osiswitch series, with a metal body and a square rod crossed rotary lever actuator. It carries a 4NC slow make/break contact configuration rated 240 VAC 3 A and 250 VDC 0.27 A, terminated via a PG13.5 cable gland with screw clamp terminals. Approvals include UL 508, CSA C22.2, and CE, with compliance to EN/IEC 60204-1 and EN/IEC 60947-5-1.
What the ratings mean for fit
The DC contact rating at 250 VDC 0.27 A is the typical constraint for this class of limit switch — expect to derate significantly when switching DC control circuits. The 240 VAC 3 A rating covers most AC pilot-duty loads up to that current. The 0.5 N-m operating force and the square-rod rotary lever suit light-to-medium cam or dog actuation in conveyors, packaging, and material handling. The metal body and PG13.5 gland make it a straightforward fit for NEMA 1 or IP54 enclosures where corrosion resistance is not the primary concern.
