The Siemens 3SE5312-0SE11 is a high-security safety position switch designed for applications requiring a guard lock function. It boasts a strong locking force of 2600 N, combined with a 24 V DC lock magnet to ensure that protective doors or guards remain secured during hazardous machine operations. The switch includes 2 NC/1 NO contacts for monitoring and is supplied without its required actuator.

This safety switch is essential for safeguarding personnel on high-risk machinery, such as industrial robots, automated assembly lines, and high-speed production equipment. The guard lock feature prevents operators from accessing dangerous areas until the machine has safely completed its cycle, significantly reducing accident potential.
