Class identity and where it sits in a panel
XCKP2521G11 is a Telemecanique-series medium duty limit switch sold under the Square D Sensors & Safety brand within Schneider Electric's industrial-switching catalog. The XCKP compact limit-switch body is the mechanical-position feedback element typically wired into a safety or sequencing circuit on a machine guard, valve actuator, or conveyor end-stop — the kind of part that lives at the edge of the panel, not on the DIN rail, and earns its keep by telling the PLC when something has physically arrived at a position. Listed product description confirms the part as Telemecanique XCKP2521G11 Limit Switch, UPC 389110316820. No further functional ratings — contact block, actuator head, electrical endurance, IP seal — appear in the available spec bundle; those details live in the manufacturer's catalog page and must be matched to the machine's mechanical and electrical requirements before the BOM line is committed.
Lifecycle and the spares-cabinet decision
Lifecycle stage is recorded as current, with the parent brand lineage identified as Schneider Electric. For a maintenance-spares buyer, current status means the part remains in normal manufacture through Schneider — one spare held against the installed machine is the cheap insurance, since a failed end-of-travel switch on a guarded cell is exactly the kind of fault that idles a line until a replacement is sourced. Independent distribution covers the line for both project-build and MRO replenishment, with availability and current pricing confirmed against an RFQ at quote time.
