It uses a magnetic field lock to hold the guard closed until the control system releases it, with a locking force of 1 200 N that keeps the door secured against forced opening during machine operation. Rated for safety applications (suitability for use as safety switch: yes), it carries four normally-closed safety-related switching contacts arranged as 2 NC + 2 NC, all with positive opening operation per IEC 60947-5-1. The slow-action contact mechanism ensures reliable break under fault conditions. The metal enclosure is painted, rated IP66, and accepts five directions of actuator approach. Screw-type terminals simplify wiring in the panel. Operating temperature range is -30 to +70 °C, making it suitable for unheated machine bays or outdoor-adjacent positions. ## Integration notes for panel builders The switch measures 56 mm wide by 144.5 mm long, with screw fixing for mounting. The separate actuator design means the actuator mounts on the guard door and the switch body on the fixed frame — alignment between the two must be maintained within the switch's actuation tolerance. Five directions of approach give flexibility in mounting orientation. Screw-type terminals accept standard control wiring; no special tools beyond a screwdriver are needed.","metaTitle":"Siemens 3SE3850-6XX00 Position Switch, 1200 N Locking Force","metaDescription":"Siemens 3SE3850-6XX00 position switch with tumbler, magnetic field lock, 1200 N locking force, IP66, 4 NC safety contacts, positive opening.
