The AZM200 Series is designed for machine/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 AZM 200 consists of a solenoid-latching interlock and actuator unit with door handle and optional emergency exit handle. The actuator is always inserted into its housing, protecting the actuator and the operator against damage and injury. Utilizing pulse-echo sensor technology, the actuator and interlock can have an offset of ±5 mm and the actuator still engages the interlock. Due to the one-hand operation of the emergency exit handle, the hazardous area can be left quickly and safely even during a power failure (when using the "unlock by power" model). The solenoid interlock is a dual channel design with two short-circuit proof, safe PNP outputs, each of which can switch up to 250 mA. With continuous internal function tests, the monitoring of the safety outputs and the use of door detection sensors, AZM 200 solenoid interlocks with one diagnostic output can be wired in series without detriment to the control category. Series wired AZM 200s continue to fulfill the requirements of Control Category 4 according to EN 954-1 with door detection sensors (without the need of a second switch).
