Compact body, IP66/67 — fits where metal switches won't
The XCPR2118N12 is a compact plastic-body limit switch — 1.22 in wide by 1.18 in deep — so it fits into tight machine guarding brackets where a standard metal switch would overhang the mounting surface. Rated IP66/67 and IK04, the enclosure handles direct hose-down and 0.5 J impact, making it a candidate for washdown zones in food processing or packaging lines where corrosion resistance matters more than brute mechanical strength.
3 A at 240 VAC — but the DC side is the real constraint
Contact rating is 3 A at 240 VAC, 0.27 A at 250 VDC — the DC derating is steep because the snap-action mechanism must break a DC arc with no zero-crossing. For a 24 VDC PLC input, the 0.27 A rating is fine; for a DC solenoid or brake, verify the inrush stays under that ceiling.
Roller lever actuator with thermoplastic head
The thermoplastic roller lever actuator resists chemicals and won't corrode in wet environments, but it is less impact-resistant than a metal lever — if the actuator takes repeated hits from fast-moving product, budget for replacement heads. Operating temperature range is -13 to 158 °F (-25 to 70 °C), covering most indoor industrial environments including refrigerated areas but not foundry or oven-adjacent positions.
Sourcing and compliance — active, quoted to order
The XCPR2118N12 carries UL 508, CSA C22.2, CE, and CCC approvals — one part number covers installations in North America, Europe, and China without switching variants. RoHS compliant with a 1/2 inch-14 TPI NPT conduit entry standard for North American metallic conduit runs. No adapter needed for rigid or flexible conduit.
