Why Choose the Pizzato ST DL820MK-E1T Safety Sensor?
The Pizzato ST DL820MK-E1T is a high-performance RFID safety sensor designed for non-contact monitoring of guards, doors and protective devices on industrial machinery. Part of the Pizzato ST D series, it uses digitally coded RFID technology to provide dependable safety interlocking while helping protect machinery against manipulation or inappropriate actuator substitution.
The ST D series incorporates redundant electronics and is designed for safety systems capable of reaching PL e and Category 4 according to EN ISO 13849-1 and SIL 3 according to EN 62061 when correctly integrated. Two safety inputs and two safety outputs allow compatible Pizzato safety devices to be connected in series, making the range particularly suitable for machinery with multiple access points and protective guards.
The ST DL820MK-E1T is configured with an E1T high coding level RFID actuator and an integrated M12 connector for convenient installation and maintenance. The E actuator provides a nominal 20 mm actuation distance, while the sensor platform offers IP67 / IP69K protection and a wide industrial operating temperature range for reliable service in demanding automation environments.
