ST DL820MK Pizzato ST D series safety sensor

Why Choose the Pizzato ST DL820MK Safety Sensor?

The Pizzato ST DL820MK is an RFID safety sensor from the Pizzato ST D series, designed for non-contact monitoring of guards, doors and protective devices on industrial machinery. RFID technology provides dependable electronic safety detection without mechanical switching elements, helping deliver a long operating life in applications with frequent machine access cycles.

The ST D platform uses redundant electronics and can be integrated into safety systems capable of achieving PL e and Category 4 according to EN ISO 13849-1 and SIL 3 according to EN 62061 when the complete safety function is correctly designed and validated. Compatible ST D sensors can also be connected in series, making the range particularly useful for automated machinery with multiple guards or access points.

The ST DL820MK features a technopolymer housing with the connection output positioned on the left and an integrated M12 stainless steel connector. It forms the sensor component of configurations that can be paired with suitable ST D RFID actuators selected according to the required coding level, actuator shape and operating distance.
