The Schmersal AZ200 pulse-echo based non-contact safety interlock, available through Davis Controls, is designed for use with movable machine guards/access gates which must be closed for operator safety. The AZ200 consists of an interlock switch 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. Using pulse-echo sensor technology, the actuator and interlock can have an offset of ±5 mm and the actuator still engages the interlock. A sensor stimulates a coil in the actuator, which in turn sends a signal back to the sensor. The pulse-echo technology provides diagnostic information and detects and indicates any misalignment at an early stage.
