Telemecanique XCKMR54D1 | OsiSense XC Heavy-Duty Limit Switch, Stay-Put Crossed Rod Lever, 2×(2 NC), Pg13.5
Telemecanique XCKMR54D1 OsiSense XC heavy-duty limit switch with stay-put crossed rods lever (6×200mm), 2×(2 NC) slow-break contacts, positive opening, IP66 metal body, Pg13.5 cable entries. 240V AC 10A Ith.
Product Overview
The Telemecanique XCKMR54D1 (Schneider Electric OsiSense XC Special series) is a heavy-duty rotary-head limit switch designed for hoisting, crane travel limits, and mechanical handling applications. It features a fixed metal (Zamak) body with a stay-put crossed rods lever (6 mm square rod, 200 mm length) providing lateral approach from two directions. The contact arrangement is 2 × (2 NC) — slow-break, staggered (break-before-make) with positive opening (forced-guided contacts) per EN/IEC 60947-5-1 Appendix A for safety circuits. Three Pg 13.5 threaded cable entries accommodate cable glands (Ø 9–12 mm). Rated Ith = 10 A, AC-15: 240 V / 3 A, DC-13: 125 V / 0.55 A.

Key Features
-
Stay-Put Crossed Rod Lever: Spring-centered or maintained-position rod (depending on cam action) — ideal for crane end-of-travel and pantograph-style actuation from either direction.
-
Double 2-NC Slow-Break with Positive Opening: Suitable for safety-related control circuits requiring forced opening of NC contacts on actuator movement.
-
All-Metal Zamak Housing: Rugged construction for foundries, hoists, conveyors, and outdoor crane applications.
-
Three Pg13.5 Entries: Flexible conduit routing — unused entries plugged with supplied blanking plugs.
-
High Mechanical Durability: 2 million cycles in demanding industrial environments.
Typical Applications
-
Overhead Cranes & Hoists: End-of-travel / overtravel limit switches on bridge and trolley motion.
-
Conveyor Systems: Belt misalignment (run-off) detection and end-stop positioning.
-
Heavy Machinery: Press guards, elevator car position sensing, and mechanical interlock duties.
-
Mining / Foundry / Steel Mill: Where dust, splash, and mechanical shock demand IP66 + metal enclosure.
XCKMR54D1 belongs to the XC Special format sub-range of OsiSense XC. For versions with 1NO+1NC or snap-action contacts, or with M20 cable entries, refer to XCKMR series variants (e.g. XCKMR54D2 etc.). Replacement/modern equivalent under Schneider's current portfolio may be referenced as XCKMR54D1H29 in some regions — verify local catalog.
