AZM170-11ZRK-24VAC/DC Datasheet PDF - Schmersal

●The AZM170-11ZRK-24VAC/DC is a 1NO/1NC safety Interlock Switch 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 and position sensor. The unit features independent actuator key (guard) position and solenoid-latching pin position contacts. It permits the prevention of machine restart until the guard is closed and the solenoid-latching pin is in the locked position. It 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.
