Siemens 3SE5 312-0SB12 Safety Position Switch

Siemens 3SE5312-0SB12 Safety Position Switch is a five‑position safety switch with guard lock from the SIRIUS 3SE5 family, designed to secure a machine guard and provide safety‑rated position sensing. It supports five directions of approach and, with a locking force of 2600 N, uses a spring‑locked escape release from the front. The device offers a 1 NO/2 NC contact arrangement and includes monitoring contacts for the actuator and magnet (2 NC/1 NO each). For this variant, the magnet voltage is 115 V AC, and the housing carries IP66/IP67 protection to withstand demanding industrial environments. The unit is supplied without an actuator; the compatible actuator model 3SE5000-0AV0 can be ordered separately to configure the complete safety switch for enclosure or guard interlock applications.
