Where it sits in the panel
The Schneider Electric XCKP2125P20RZ is a Telemecanique-series medium-duty limit switch used to detect position end-of-travel on moving parts — guard-door status, cylinder limits, conveyor diverters — where a mechanically rugged snap-action body outlasts a proximity sensor under repeated impact loading. It is catalogued under Medium Duty Limit Switches, which positions it between light-duty panel-mount switches and heavy-duty foundry-class bodies: enough mechanical life for general factory machinery, not rated for the high-cycle, contaminated environments of forging or casting lines.
Production status and brand lineage
The brand carries two names on the data sheet: Schneider Electric as the corporate owner, with Square D Switches & Sensors as the brand-mark on the body and Telemecanique as the legacy series designator — both point to the same physical part.
Traceability across PO and packing slip
UPC 12-digit 389119078088 is the shipping-unit identifier on the carton label, useful when reconciling a Schneider factory carton against the line-item on the purchase order without opening the box.
