Area of application The door contacts with positive break of the AZ series are available in ten different versions so that a suitable contact for monitoring the door position or the locking mechanism (hook bar) is available for all types of elevators. They are tested and certified in accordance with the European and American standards.
Design With the AZ safety switches, the switching element and actuator are not connected to each other in terms of the design. However, when they are switched they are joined together functionally or separated. When the safety device is opened, the actuator is separated from the base device. In the process, the NC contact in the safety switch is opened through positive breaking.
Round or elongated holes serve to attach the switch; on some types, captive securing bolts are included in the scope of delivery.
