Lifecycle read for the BOM line
The XCPR2121G13: Tracing identifier UPC 389110210722 lets a buyer reconcile the part against incoming-receipt records and the factory carton label when lot integrity matters on a maintenance spare.
Field notes for panel-side installation
As a medium-duty limit switch, the XCPR2121G13 is specified for the typical industrial-door, conveyor-end, and actuator-position duty where a robust snap-action mechanism and a sealed body are needed — it is wired into the safety or control circuit at the machine, not the panel, so the on-site decision is mechanical mounting and cable entry rather than DIN-rail fill. Confirm the actuator head style, contact configuration (snap-action, slow-make, or snap-action with overlapping contacts), and conduit entry thread against the BOM call-out before committing the line; the order code encodes the head and contact arrangement, and a swapped suffix on the same series changes the wiring interface even when the catalog description looks identical.
Sourcing posture for a stock-out
Independent-distribution sourcing covers the XCPR2121G13 against an RFQ — production quantities are quoted to the BOM line with lead time and current pricing confirmed at quote time, and lot-specific date codes are available where the maintenance spare requires traceable stock.
