(900 operations/hour,
24 V AC/DC 0.1 A resistive load)
Interlock force 500 N min. (GS-ET-19)
(Note): The actuator locking strength is rated at 500 N of static load. Do not apply a load higher than the rated value.
Do not apply a load higher than the rated value.
When a higher load is expected to work on the actuator, provide an additional system consisting of another safety switch without lock (such as the SG-A1 safety switch) or a sensor to detect door opening and stop the machine.
