Why Choose the Pizzato ST GD420N5-D0T ST G Series Safety Sensor?
The Pizzato ST GD420N5-D0T is a compact RFID safety sensor with coded actuator designed for non-contact monitoring of guards, doors and access points on industrial machinery. Part of the Pizzato ST G series, it combines electronic RFID detection with a compact symmetrical housing to provide dependable safety interlocking for automated machinery and production systems.
The ST GD420N5-D0T provides two safety inputs IS1–IS2, two safety outputs OS1–OS2, one signalling output O3 and one programming input I3. This configuration supports integration with safety modules and safety PLCs and enables compatible sensors to be incorporated into series-connected machine safety architectures.
Operating from a 24 V DC supply, this variant is supplied with an integrated 5 m PVC cable and the SM D0T low-level coded actuator. The D-style actuator provides fixing on two levels and an approximately 11 mm rated actuation distance, while the sensor's IP67 and IP69K protection ratings support installation in demanding industrial environments.

Reliable Safety Monitoring for Industrial Automation
RFID safety sensors such as the Pizzato ST GD420N5-D0T monitor movable machine guards without requiring mechanical contact between the sensor and actuator. When the actuator leaves the permitted sensing area, the electronic safety outputs change state so that the connected safety controller can initiate the required safe machine response.
The ST G series is designed for machine builders requiring compact dimensions, flexible mounting and reliable coded guard detection. The symmetrical sensor housing simplifies installation on different guard orientations, while the D-style actuator's two-level fixing arrangement provides additional mechanical flexibility when positioning the actuator on machinery.
Typical Applications
- Machine guard doors and access panels.
- Industrial production and assembly machinery.
- Robotic cells and enclosed automation systems.
- Packaging and processing equipment.
- Food and pharmaceutical production machinery.
- Safety interlocking systems using safety PLCs or safety modules.
