Siemens 3SE5 112-0CD02 Roller Plunger Limit Switch

Siemens 3SE5 112-0CD02 Roller Plunger Limit Switch is a 40 mm metal‑enclosed position switch designed for end‑of‑travel sensing in automation equipment. The 3SE5112-0CD02 variant features a roller plunger actuator with 3 mm overtravel and a stainless‑steel roller about 13 mm long, housed in a rugged metal enclosure that complies with EN 50041 mounting standards. It provides 1 NO/1 NC quick‑action contacts in a single‑pole double‑throw configuration and uses a single M20 x 1.5 device connection for field wiring. The actuating/restoring force is specified at 30 N, ensuring consistent operation under typical machine motion. This switch is commonly used for limit detection in conveyors, presses, robotics, and other equipment requiring reliable end‑of‑travel signaling, offering durable performance in industrial environments thanks to its robust roller plunger mechanism and metal housing.
