The sensorPro contactless safety switch family now includes RFID-coded sensors that provide flexible protection against unauthorized access or manipulation for machine operators and equipment. The RFID-enabled STS series safety switches are available in three coding options: unique, which exclusively accepts input signals from its factory-paired actuator; fully coded, which can be programmed to accept input from a specific STS actuator; and coded, which can accept input from any STS actuator. The contactless devices can be used as stand-alone safety switches or wired in series (cascaded) in sets of up to 30 sensors, while maintaining PLe/Category 4 safety ratings.
