Schmersal AZM 400 bolt locking safety interlock

The Schmersal AZM 400 has been designed for applications where large, heavy doors with high manual forces are present or in applications where motor-driven doors are used. The utilisation of a motorised bolt locking mechanism provides a bi-stable operating principle, meaning in the case of a power loss the locking device will remain in its last known position. The AZM 400 is capable of a locking force of up 10,000 N. A lateral force on the door is also acceptable up 300 N while maintaining the ability to unlock the device under lateral load.

High-level coding has been realised by the inclusion of an RFID tag in the actuator. An RFID signal passes from the actuator to the locking device providing unique information about the actuator being used, eliminating any potential for defeat of the safety system. Dual signal inputs for control of the locking pin and dual diagnostic outputs allow for easy integration into existing safety systems and dual safety outputs make the AZM 400 suitable for use in CAT PLe safety systems.
