The AZM400 is a safety rated motorized bolt lock with an integrated RFID based electronic safety sensor.

Operating Principle:
The Aluminum die-cast body contains the RFID sensor and a motor-driven locking bolt, which fits into the hole of the actuator block with the matching RFID target. Once locked, the solenoid bolt provides a locking force of 10,000 N. The motorized AZM400 is a bi-stable system, thus in the event of a power failure the switch maintains the last locked status of the interlock.

In addition, the AZM400 uses RFID to detect the actuator and indicate a closed guard. This non-contact operating principle limits wear on components, tolerates misalignment, and offers the option of individual coding.

Intelligent Locking:
The AZM400 can detect if the locking bolt has been blocked from reaching a "locked" state. Before reporting a fault the switch will make a second autonomous attempt at locking, therefore reducing the number of error messages and protecting the device and machine from damage.

Safety Classification:
The AZM400 series is compliant with North American and International standards such as cULus and CE. Its two-channel input signal meets PLe/Category 5 (ISO 13849) or SIL3 (IEC 61508) for both its interlock and guard locking function. It is a Type 4 interlock per ISO 14119, with a high coding level with the individual coding option (I1 or I2).
