SCHMERSAL AZM170-02ZRK-24VAC/DC Limit Switch, 2NC, 4 A, 230 V

The AZM170-02ZRK-24VAC/DC is a Safety Interlock Switch with screw terminals for fast installation, 2NC contacts and IDC method of termination. The AZM170 series switch 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.
