The Schmersal Group is presenting a new compact solenoid interlock based on RFID at SPS 2019 in Nuremberg: Measuring 119.5 x 40 x 20 mm, the AZM40 is the smallest electronic solenoid interlock in the world. This makes it particularly suitable for smaller safety gates and flaps.
Thanks to the 180° angular flexibility of the actuator, it can be infinitely adjusted to the AZM40 so that the guard locking can also be used for flaps that do not close at a 90° angle or flaps that open upwards at a 45° angle. This means that the Angular flexibility This means that the guard locking can also be easily installed in confined and inaccessible areas. The AZM40 can also be easily mounted on standard 40 mm profiles without any protrusion.
„The solenoid interlock meets the requirements of many users who want space-saving solutions, as space requirements are a decisive cost factor in production.“
Stephan Frick, Product Manager at Schmersal
Despite its small design, the AZM40 has a high power rating. Locking force of 2,000 newtons. „A guard locking must be selected so that it can withstand the expected forces. With a locking force of 2,000 newtons, the user is also on the safe side with regard to the standardised recommendations,“ explains Stephan Frick.
Thanks to integrated RFID technology the „high“ coding level is achieved. This means that the guard locking offers increased protection against tampering in accordance with the requirements of DIN ISO 14119.
The AZM40 works according to the bistable operating principleIt retains the current position in the event of a power failure. This ensures safe operation in every operating state of the machine. Even in the event of a power failure, the safety gate remains securely closed during dangerous overtravel movements.
Another advantage of the bistable operating principle is the permanent Lower energy consumption, because the guard locking only needs to be energised when the door is to be locked or unlocked.
For applications with personnel protection (guard locking monitored), the safety outputs are switched on when the safety guard is closed and guard locking is disabled.
The AZM40B version (actuator monitored) can be used for applications with process protection. With this variant, the safety outputs are already switched on when the safety guard is closed. It is not absolutely necessary to disable guard locking with this device.
