The Schmersal AZM 200 Series pulse-echo based non-contact safety interlock is designed for use with movable machine guards/access gates that must be closed for operator safety. The AZM 200 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. The pulse-echo technology provides diagnostic information and detects and indicates any misalignment at an early stage.
