Siemens 3SE5 Safety Interlock Switch, 2NC/1NO, Keyed, Metal

The Siemens 3SE5 position safety interlock switches are designed to ensure that the safety mechanism on protective doors cannot be deactivated. Also, the multiple mechanical coding of these interlock switches virtually eliminates the possibility of tampering. It has auxiliary contacts of 2NO/1NC configuration with maximum 6A current rating. The separate actuator is mounted directly on the protective door and moves into the opening on the switch when the door is closed. Once the door is opened, the actuator is removed from the switch and the NC contacts open breaking the circuit safely and reliability.
Note:
Actuators must be purchased separately.
