SCHMERSAL AZM 161-B1

Solenoid Interlock Actuator

The AZM161 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 monitoring contacts. There is a mechanical linkage preventing the solenoid position contacts from changing unless the key is inserted (guard closed). The AZM161 consists of an electromechanical safety interlock switch section with "positive-break" NC contacts and an actuator key. In addition, the solenoid mechanism features 1 NO and 2 NC solenoid-latching monitoring contacts, 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).
