“The solenoid interlock meets the requirements of many users looking for space-saving solutions, as space required is a decisive cost factor in production,” explains Stephan Frick, Product Manager at Schmersal.
Despite its compact size, the AZM40 has an amazing 2000 Newton interlocking force. “An interlock must be selected to withstand the anticipated forces. With interlocking force of 2000 Newtons, users are on the safe side with respect to the recommendations in the standard,” explains Stephan Frick.
Thee integrated RFID technology allows a coding level of “high”. This means the interlock offers increased tamper protection in accordance with the requirements of DIN ISO 14119.
The AZM40 works on the bistable principle: In the event of a power cut, it retains the current position. This ensures safe operation, whatever the status of the machine. Even if there are hazardous run-on movements, the safety door remains safely locked in the event of a power failure. Another advantage of the bistable principle is the consistently low energy consumption, as the interlock only requires power when the door is to be locked or unlocked.
For applications with personnel protection (interlock monitored), the safety outputs are switched on when the safety door is closed and the interlock locked.
The AZM40B model (actuator monitored) can be used for applications with process protection. In this variant, the safety outputs are actuated as soon as the safety door is closed. With this device, locking the interlock is not absolutely necessary.
