The wide range of Pizzato Elettrica in the machines security sector now is integrated with the introduction of new safety sensors with RFID technology ST series. The sensors, combined with appropriate safety modules, are suitable for controlling protections and guards, allowing the system where they are incorporated to attain a safety category up to SIL 3 according to EN 62061 standard and up to PL e according to EN ISO 13849-1 standard. These sensors use RFID (Radio Frequency IDentification) technology: the unique digital code contained in the actuator can guarantee the system where they are installed a high level of safety and reliability, also preventing possible tampering of the sensor.
