Siemens Safety position switch with tumbler Locking force Part number 3SE5312-0SB11

Product Overview

The 3SE5312-0SB11 is a SIRIUS mechanical safety position switch with tumbler featuring a locking force of 2600 N, 5 directions of approach, and solenoid-locked operation. This safety switch operates on 24 V DC magnet voltage and provides monitoring capabilities for both actuator (2 NC/1 NO) and magnet (2 NC/1 NO). The device is supplied without actuator - Actuator 3SE5000-0AV0 must be ordered separately. This safety position switch is designed for position monitoring of moving protection equipment to ensure protective doors, covers, or protective flaps remain closed during hazardous operations.

Applications

The 3SE5312-0SB11 is specifically designed for protective doors that must remain closed while a machine is being shut down. Ideal applications include industrial machinery guards, safety gates, access panels, and protective enclosures where high locking force and fail-safe operation are critical. The solenoid locking ensures doors remain secured until receiving the appropriate unlock signal, making it perfect for applications requiring power-to-unlock functionality.

Important Notes
