4008321206 Safety Component Schmersal Solenoid-Latching Safety Interlock Switch AZM161CC-12/12RKEU-024 Woodworking Machinery Tools and Spares For Homag Machine

Product Description

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).

Product Details

Product Operation

The AZM161 electromechanical safety interlock switch assembly consists of a rugged switch-solenoid-latching mechanism and a geometrically-unique locking actuator key. The switch actuating key is typically mounted to a movable machine guard.

When the guard is closed, the actuating key is held in position by the solenoid-latching mechanism. The guard may only be opened by energizing or de-energizing (depending upon model) the solenoid-latching mechanism.

Upon opening of the guard, the switch’s “positive-break” NC contacts are forced to open through a direct (non-resilient) mechanical linkage with the actuating key. The NO contacts close upon key removal.

The machine is prevented from starting until the actuating key is inserted (guard is closed) and the solenoid has locked it in the closed position.

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 “solenoidunlocking” models … for application versatility.

• Meets rigid safety agency standards … IEC, BG, UL and CSA.

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