With dimensions of 119.5 x 40 x 20 mm, the AZM40, according to Schmersal, it is the smallest electronic solenoid interlock in the world. Despite its small size, the AZM40 has a high locking force of 2,000 Newtons. The solenoid interlock is suitable for applications up to cat. 4 / PL e / SIL 3 (interlocking function).
A series connection is possible without reducing the level of safety. The RFID-based safety sensors developed by Schmersal allow individual coding, therefore, the AZM40 offers the highest protection against manipulation according to the requirements of DIN ISO 14119. The AZM40 also operates according to the bistable principle, i.e. it maintains the current position even in the event of a power failure. This ensures safe operation in any operating state of the machine. At the same time, this reduces power consumption because the guard locking only needs to be energized when the door is to be locked or unlocked.
