Schmersal AZM 400 bolt locking safety interlock

Schmersal has added the AZM 400 safety interlock to its line-up of guard locking devices, specifically designed for applications where large, heavy doors with high manual forces are present or in applications where motor-driven doors are used.

Using a motorised bolt locking mechanism provides a bi-stable operating principle, meaning in the case of a power loss the solenoid locking device will remain in its last known position. It is capable of a locking force of up 10,000 N. A lateral force on the door is also accepted up to 300 N while maintaining the ability to unlock the device under lateral load. The product also features an emergency exit or manual release.

High-level coding is possible 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 and thereby eliminating any potential for defeat of the safety system. Dual signal inputs for control of the locking pin and dual diagnostic outputs also allows for easy integration into existing safety systems, while dual safety outputs ensure the product is suitable for use in CAT PLe safety systems.
