The Telemecanique XCKMR1656363 is a heavy-duty limit switch from the OSISENSE XC family, built for rotary-head applications with a spring return roller lever actuator. It lands with 1 NC + 1 NO contacts, screw-clamp terminals taking 0.34–2×1.5 mm² wire, and an IP66 enclosure rated IK05. This is a current-production part – no obsolescence drama, no last-time-buy scramble. If you're sorting a pallet pull, this is the kind of switch you move fast: active, compliant, and ready to slot into a panel.
Sourcing & Lifecycle
Lifecycle stage is marked current – no PCN, no EOL, no LTB on record. This switch is in standard production through the Telemecanique/Square D channel. For a BOM line that needs a fast fill, quote it to order; no supply-chain headache here.
Mounting & Wiring
Mounts by the body – three-hole pattern at 30 mm, 52 mm, and 72–72 mm centers. Screw-clamp terminals accept 1×0.34 to 2×1.5 mm², stranded or solid. The head is a fixed metal rotary with spring return roller lever; no wobble in the actuator. Operating range is -25 to 70°C – fine for most industrial cabinets.
