PRESS RELEASE
One giant leap for safety: AZM400
Schmersal presents new solenoid interlock for heavy safety doors at
SPS IPC Drives trade fair
Visit Schmersal at SPS IPC Drives from 24 to 26 November 2015 in Nuremberg:
Hall 9, Stand 460
Wuppertal/Nuremberg, 24 November 2015.At the SPS IPC Drives trade fair, the Schmersal Group is presenting an extension of its programme of solenoid interlocks. Characteristic properties of the AZM400 include the very high clamping force, the bistable active principle and the electro-motorised locking pin. This means that the new range is also suitable for very large, motorpowered safety doors, e.g. at CNC processing centres. The combination of electronics and sensors represents a high level of availability as well as interesting additional functions with a very high level of safety.
The fail-safe AZM400 bolt interlock consists of a locking unit with sensor technology and a motordriven 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 clamping 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 locking function but also the clamping function, the bolt lock achieves PL e and cat. 4 according to DIN EN ISO 13849-1 aswellas SIL 3 according to IEC 61508. The high level of safety for the clamping 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 locking status of the interlock in the event of a power failure. Even if the power supply should be interrupted the safety door remains securely interlocked to protect against hazardous run-on movements.
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.
