The solenoid interlocks of the AZM series have been designed to prevent, in conjunction with the control part of a machine, e.g. fail-safe delay timers or fail-safe standstill monitors, sliding, hinged and removable safety guards such as fences, flaps or doors, from being opened before hazardous conditions (e.g. run-on movements) have been eliminated.
These solenoid interlocks are also used for cases in which the opening of a guarding device represents a non-permissible intrusion in a production process.
