Solenoid interlock
SCHMERSAL

AZM range solenoid interlocks, operating in combination with control elements of a machine, e.g. fail-safe standstill monitors or fail-safe delay timers, ensure that sliding, hinged and removable guarding devices, such as grids , hoods or doors, cannot be opened until hazardous conditions (e.g. running-down movements) have come to an end.

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.

In combination with AES and AZR range safety monitoring modules, the AZM range solenoid interlocks achieve Control Category 3 or 4 to EN 954-1, subject to suitable circuit arrangements. Examples of circuits for solenoid interlocks are shown in the Schmersal Control Circuit and Applications Handbook.

Schmersal make both standard and AS-i Safety at Work solenoid interlocks.
