Product description

The Siemens 3SE5312-1SB11 is a high-performance safety position switch featuring a solenoid-locked mechanism and a robust locking force of 2600 N. It is equipped with a 24 V DC magnet for secure guard locking and includes integrated LED indicators (yellow/green) for status visualization. This switch provides 2 NC/1 NO contacts for safety and signaling and requires a separate actuator.

This solenoid-locked switch is essential for protecting personnel on machinery where immediate stopping and secure guarding are critical.
