Body, head, and what snaps
The XCMD21500L1 ships as a compact, double-insulated plastic-body limit switch with a thermoplastic roller lever plunger head, sized 1.22 in W x 1.18 in D x 2.56 in H and wired through a 1/2 inch NPT entry. Contact rating is 240 VAC at 3 A and 250 VDC at 0.27 A — low-current pilot duty, not a power contactor job; the right comparator is a PLC input card, an interlock loop, or a safety relay coil.
Enclosure rating and where it lives
Sealed to NEMA 1/4/12 and IP65, the housing tolerates dust and water-jet washdown — fine for a conveyor end-of-line station or a packaging cell where hosedown happens between shifts, with an operating envelope from -13 to 158 deg F. Branding on the nameplate reads Square D Co. with the Osiswitch / Osisense Telemecanique lineage behind it; UPC 78590126962 (12-digit 389110305640) is the cross-border paperwork identifier if the order has to clear customs in a region where the original channel does not stock it.
Lifecycle status and sourcing posture
RoHS compliance is stated on the technical description; California Proposition 65 warning covers DINP and DIDP exposure from the housing materials, which has to travel with the shipper paperwork for any lot entering California.
