Siemens 3SE5112-0CC02 Limit Switch Plunger Actuation

Siemens 3SE5112-0CC02 is a metal-enclosed limit switch in the 3SE5 family, designed for end‑of‑travel sensing and basic position signaling in industrial automation. It features a long‑pin plunger actuator and 1 normally open plus 1 normally closed (NO/NC) snap‑action contact pair, giving both NO and NC outputs from a single device. The unit uses a 40 mm metal enclosure per EN 50041 with a single M20 x 1.5 entry, and carries an IP66 rating for dust and water jet protection in harsh environments. Electrical specifications reach up to 10 A at up to 400 V AC, making it suitable for control circuits and machine automation where robust dual‑signal feedback is required. Typical applications include conveyors, presses, and packaging lines where reliable position sensing and interlocking signals are needed to coordinate machine cycles and safety logic.
