Why Choose the Pizzato ST GD820MK Safety Sensor?
The Pizzato ST GD820MK is a compact and robust RFID safety sensor designed for reliable non-contact monitoring of machine guards, access doors and other movable protective devices. As part of the advanced Pizzato ST G series safety sensor range, it uses coded electronic detection to provide dependable guard monitoring in demanding industrial safety and automation applications.
The ST G series combines RFID-based guard monitoring with redundant electronic safety technology and a durable monolithic technopolymer housing. Its symmetrical design allows the same sensor to be installed on both left- and right-hand guards, while the 22 mm mounting-hole spacing makes the series suitable for upgrading compatible traditional magnetic safety sensors to RFID technology.
The ST GD820MK is supplied as the sensor unit without an actuator and features an integrated M12 stainless steel connector. With a compact housing, IP67/IP69K protection and actuation from multiple directions when used with a compatible ST series actuator, it is well suited to demanding industrial machine guarding applications.

Reliable Safety Monitoring for Industrial Automation
RFID safety sensors such as the Pizzato ST GD820MK provide non-contact monitoring of machine guards and access points. The sensor detects its compatible coded actuator electronically, allowing the safety control system to determine whether the protective device is correctly positioned before permitting hazardous machine functions.
The ST G series provides redundant electronic safety technology with two safety inputs, two safety outputs, a signalling output and a programming input. The safety outputs can be integrated with compatible Pizzato safety modules or safety PLCs with OSSD inputs, while suitable ST sensors can be connected in series to create efficient safety chains.
The integrated M12 stainless steel connector provides a robust connection arrangement for industrial installations. The monolithic housing is free from encapsulation resin and, together with IP67/IP69K protection, is designed for demanding environments including applications requiring frequent cleaning.
