The SCHMERSAL AZM40, measuring 119.5 x 40 x 20 mm, boasts the title of the world's smallest electromagnetic safety lock. This makes it especially suitable for small safety gates and flaps. Thanks to its 180° flexible actuator, the AZM40 can be approached seamlessly, allowing it to be utilized on barriers that cannot close at 90° or open upwards at a 45° angle. This angular flexibility facilitates easy installation in compact and hard-to-reach spaces. Furthermore, the AZM40 can be mounted on standard 40 mm profiles without protrusion.

　　"Space requirement is a decisive cost factor in production, and this electromagnetic safety lock meets the needs of many users seeking space-saving solutions," said Stephan Frick, Product Manager at Schmersal.

　　Despite its compact size, the AZM40 boasts a locking force of up to 2000 N. "An electromagnetic lock must withstand the expected forces. According to recommendations in standards, a locking force of 2000 N ensures safety for users," explained Stephan Frick.

　　Integrated RFID technology enables a "high" coding level, which means that this electromagnetic safety lock offers enhanced tamper-proof protection, complying with DIN ISO 14119 requirements.

　　The AZM40 operates based on a bistable principle: in the case of power failure, the AZM40 retains its current position. This ensures safe operation regardless of the machine's state, ensuring that safety gates remain securely locked even during power outages or hazardous operational movements. Another advantage of the bistable principle is consistently low energy consumption, as the electromagnetic lock only requires power when locking or unlocking the door.

　　For applications with personnel protection (electromagnetic lock monitoring), the safety output is activated when the safety gate is closed and the electromagnetic lock is engaged. The AZM40B (actuator monitoring) variant is suitable for applications with process protection functions. In this model series, the safety output is activated once the safety gate is closed, eliminating the need to lock the electromagnetic lock separately.
