Compact plunger head, IP67 body
The XCKT2510N12: The wide plastic housing is rated NEMA 1/2/4/6/12/13 plus IP66 and IP67, so the same body works on indoor panels and on outdoor or washdown machinery without a separate boot — a meaningful consolidation for panel builders who would otherwise stock a second switch for wet zones. Operating temperature spans -13 to 158 DEG F, covering most factory-floor enclosures without a heater strip or a cold-weather derate on the seal stack.
Contact rating and what it drives
Termination is 1/2 inch NPT conduit entry with screw clamp terminals, matching the standard cable gland on most US-style machine enclosures and accepting the same ferruled conductors used elsewhere in the panel. Total travel is 5 mm against 0.9 mm differential travel — the 5 mm overtravel gives the cam some margin against an over-travel event without bending the plunger, while the short differential travel keeps the snap point close to the actuator face for repeatable position feedback.
Standards and approvals on record
The part is approved to UL 508 and CSA C22.2, and is built to EN/IEC 60204-1 and EN/IEC 60947-5-1 — the IEC 60947-5-1 line covers low-voltage switchgear control devices, so the contact ratings are stated under that standard rather than the older UL 508 alone, which matters for OEMs shipping machinery globally. UPC 78590126954 (12-digit 785901269540) is the factory trace code carried on the box label, the same identifier an incoming-inspection clerk can match against the packing slip without pulling the switch out of its carton.
Sourcing posture for this code
The XCKT body and the Osiswitch head line are still the standard Schneider Electric family for general-duty limit switches, meaning replacement units in the field match the footprint and the actuator pattern — a maintenance spare from this listing bolts back onto the same mounting holes and picks up the same cam profile without a re-tool.
