The compact AZM170 Series is designed for machines/work cells where access to a hazardous work area must be controlled until safe conditions exist. Their solenoid-latching feature permits locking a machine guard until dangerous conditions, which may exist immediately after removal of power, have abated. Solenoid-latching may be controlled by a time delay, motion detector, position sensor or other suitable component.

The unit features independent actuator key (guard) position and solenoid-latching pin position contacts. These permit the prevention of machine restart until the guard is closed and the solenoid-latching pin is in the locked position.

The AZM170 consists of an electromechanical safety interlock switch joined to a solenoid-latching mechanism. Both the safety switch and solenoid mechanism feature "positive-break" contacts. In addition the actuator key features a built-in latch (unlocked key holding force of 7 pounds), and an auxiliary manual unlocking device … the latter provided to aid in installation and for use in the event of a power failure (when using the "unlocking by solenoid" model).

Each unit is supplied with a cord grip and a cap to seal the unused key entry port in the solenoid-latching mechanism.
