Siemens Actuator Head for Use with 3SE5 Limit Switch

Actuators must be purchased separately. 3SE5 Series, Standard. The SIRIUS 3SE5 position 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. 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 reliably. 5 directions of approach, from above and 4 x 90° IP67 degree of protection Protection up to Cat 4 (EN 954-1), Up to SIL 3 IEC 62061 Simple, fast wiring offers approx 20 to 25% reduction in connection time ASIsafe electronics are now integrated into the enclosure for additional space saving LED versions available for on-site diagnosis Slow action contacts Screw terminals
