The wide plastic body resists corrosion and impact better than painted metal in caustic or humid atmospheres — a common spec for chemical plants and marine-adjacent installations. ## Contact ratings — AC vs DC derating matters Rated 240 VAC 10 A and 250 VDC 0.27 A — the DC rating drops sharply because DC arcs do not self-extinguish at zero crossing. For a 24 VDC control circuit the switch handles the full 10 A resistive; at 250 VDC the 0.27 A limit governs inductive loads like DC solenoid valves. The 1NO-1NC slow make/break contact configuration provides positive break on the NC channel — required by EN/IEC 60947-5-1 for safety interlock circuits where the NC contact must open even if welded. ## Approvals and applicable standards UL 508 listed and CSA C22.2 certified for North American industrial control panels; also complies with EN/IEC 60204-1 and EN/IEC 60947-5-1 for European machinery — covers the two major regulatory frameworks without additional component-level testing. Operating temperature range -13 to 158 °F (-25 to 70 °C) covers most indoor industrial environments and unheated outdoor enclosures in temperate climates. ## Actuator and connection details Thermoplastic roller lever actuator — the roller follows cam profiles or machine slides without wearing the lever; the thermoplastic head resists cracking in cold environments better than phenolic. 1/2 inch NPT conduit entry with screw-clamp terminals — standard North American trade size for rigid or flexible metal conduit; the screw clamps accept up to 14 AWG stranded without ferrules.","metaTitle":"Telemecanique XCKT2518N12 Limit Switch, 240VAC 10A, IP66/67","metaDescription":"Telemecanique XCKT2518N12 limit switch, 240 VAC 10 A / 250 VDC 0.27 A, 1NO-1NC, NEMA 1/2/4/6/12/13 IP66/IP67.
