Non-Contact safety switches are designed for the use on safety doors, safety guards or safety covers that are used in several applications, e.g. on machine tools or on flaps in the food industry. If the door is opened, the plant is automatically shut down safely.  All safety switches of the ZCode series operate in a non-contact manner via an encoded magnet system with a large switching distance and high tolerance against offset to the safety door. These can be actuated only with the actuator included in the scope of supply. The switching status is indicated by a LED.
