What the Category Means for Fit
Heavy Duty Limit Switches are built for environments where standard limit switches fail — high vibration, washdown, or repeated mechanical impact. The XCKMR54D1H29EX fits into the same mounting footprint as other Telemecanique XCK-M series bodies, so if you're swapping a failed unit on a conveyor or machine tool, the mechanical interface and actuator style should match without re-drilling the panel or re-routing the conduit.
