Electric shock protection class

Class II (IEC 61140)(Note), 回(double-insulated)
(Note): Basic insulation of 2.5 kV impulse withstand voltage is ensured between different contact circuits.
When both SELV (safety extra low voltage) or PELV (protective extra low voltage) circuits and other circuits (such as 230 V AC circuits) are used for the solenoid power and contact circuits at the same time, the SELV or PELV requirements are not met any more.

Interlock force

1,400 N min. (GS-ET-19)(Note)
(500 N min. : SG-K24 actuator)
(Note): The actuator locking strength is rated at 1,400 N of static load. 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.

Direct opening travel

11 mm 0.433 in min. (actuator : SG-K21)
12 mm 0.472 in min. (for other actuators)
