One giant leap for safety: AZM400

Characteristic properties of the AZM400 include the very high holding force of 10,000 N, the bistable active principle and the electro-motorised locking bolt. This means that the new range is also suitable for very large, motor-powered safety doors, e.g. from CNC processing centres. The combination of electronics and sensors represents a high level of availability from the user's perspective as well as interesting additional functions with a very high level of safety.

The fail-safe AZM 400 bolt interlock consists of a locking unit with sensor technology and a
motor-driven locking bolt, along with an actuator that features an encoded RFID-tag and a locking hole in which the locking bolt engages. As soon as the locking bolt has reached sufficient depth, the guard system is considered to be safely locked. Here, the AZM400 reaches a holding force of 10,000 N.

By integrating RFID technology in the safety sensors, the coding level high is reached for the individually encoded versions in accordance with ISO 14119. Not only with the interlocking function but also the guard locking function, the bolt lock achieves PL e and cat. 4 according to DIN EN ISO 13849-1
as well as SIL 3 according to IEC 61508.  The high level of safety for the guard locking function is attained among other ways by the two-channel unlocking signal. This ensures that the system is not unlocked unintentionally, for example, in the event of a cross connection. Uncontrolled access to hazard areas is thereby prevented in this way.

The AZM400 is a bistable system, which maintains the last locked status of the interlock in the event of a power failure. Even with hazardous run-on movements, the safety door remains securely interlocked if the voltage supply should be interrupted.

The AZM400 makes unlocking against lateral forces of up to 300 N possible. In this way, interruptions in the production process are avoided and productivity of the machines and systems is increased. Thanks to the integrated safety-related sensor technology, the bolt position can be monitored and fault conditions identified. Consequently, the number of fault messages is reduced, which likewise contributes towards greater productivity.

The new type of input circuit for actuation of the guard locking function makes it possible to connect the AZM400 to all common safety control systems. These safety control systems can be equipped both with P/P and P/N outputs. To do this, no different versions of the AZM400 are necessary.
