The Telemecanique XCSM3902L1 is a miniature metal safety limit switch. Its plunger head has a plastic cover secured by a 5-lobe safety screw; the operator is a roller plunger for lateral approach, actuated by a 30° cam. Contacts are 1 NC + 1 NC + 1 NO, snap action, with positive opening of the NC contacts (minimum 35 N). Minimum tripping force is 7 N and repeat accuracy on the tripping points is 0.05 mm. It is pre-cabled with a 1 m, 7 × 0.5 mm² cable. With appropriate monitoring it can reach category 4, PL e and SIL 3.
Rated operational current is 1.5 A at 240 V in AC-15 and 0.1 A at 250 V in DC-13. Rated insulation voltage is 400 V to IEC 60947-5-1 and rated impulse withstand voltage 4 kV. Mechanical durability is 10,000,000 cycles and B10d is 50,000,000; maximum actuation speed is 0.5 m/s. Body and head are Zamak; dimensions are 30 × 70 × 16 mm and weight is 0.17 kg. Operating temperature is -25 to +70 °C. Degrees of protection are IP66, IP67 and IP68, with impact protection IK06. The switch is CSA and UL certified.
