Schmersal AZM40 electronic solenoid interlock

The AZM40 by Schmersal is a small electronic solenoid interlock with dimensions of 119.5 x 40 x 20 mm.

It is suitable for small safety doors and flaps that do not close at 90° or those that open upwards to a 45° angle, due to its 180° flexible actuator.

Despite its compact size, the product has a 2 kN interlocking force, in addition to its integrated RFID technology for increased tamper protection.

Even in the event of a power failure, the interlock retains its current position to enable safe operation whatever the status of the machine and remains safely locked.

Another advantage of the bistable principle is the consistently low energy consumption, as the interlock only requires power when the door is to be locked or unlocked. It features optimised symmetrical mounting on 40 mm profiles that can be bolted on either side, with LEDs visible from three sides.

For applications with personnel protection (interlock monitored), the safety outputs area is switched on when the safety door is closed and the interlock locked. The AZMB40B model (actuator monitored) can be used for applications with process protection. In this variant, the safety outputs are actuated as soon as the safety door is closed.
