Solenoid-Latching Safety Interlock Switch

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. These permit the prevention of machine restart until the guard is closed and the solenoid-latching pin is in the locked position.

The AZM161 consists of an electromechanical safety interlock switch with "positive-break" contacts and a locking actuator key. In addition, the solenoid mechanism features a NO and a NC solenoid-latching monitoring contact, 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).

Features & Benefits:

• Solenoid-locking design … controls access to hazardous areas until safe conditions exist.

• Highly tamper-resistant … difficult to defeat with simple tools, tape, bent wires, etc. Reduces liability exposure.

• "Positive-break" NC contacts … assure circuit interruption upon actuator key removal.

• Conditional "safe" outputs … actuating key must be fully inserted and solenoid must be actuated to lock key before "closed" safety signal is provided.

• Watertight design … meets IP67 environmental requirements.

• High-strength, stainless-steel actuator key … tolerates mechanical abuse without damage.

• Rugged, corrosion-resistant housing … tolerates hostile environments.

• Four optional key entry locations … provide installation flexibility.

• Independent actuator key position and locking pin position monitoring contacts … provide a higher degree of safety.

• Available in "solenoid-locking" and "solenoid-unlocking" models … for application versatility.

• Meets rigid safety agency standards … IEC, BG and VDE (UL and CSA pending).

• Wide selection of accessories … to meet diverse application requirements.
