Why Choose the Pizzato ST GD420N5 ST G Series Safety Sensor?
The Pizzato ST GD420N5 is a compact and highly reliable RFID safety sensor designed for non-contact monitoring of guards, doors and access points on industrial machinery. As part of the advanced Pizzato ST G series, it uses RFID technology and electronic safety outputs to provide dependable machine guarding and safety interlocking for automated production systems.
The ST GD420N5 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, while the safety inputs and outputs enable compatible devices to be incorporated into series-connected machine safety architectures.
Operating from a 24 V DC supply, this N5 version is supplied with an integrated 5 m PVC cable. The sensor itself is supplied without an actuator, allowing a suitable ST series RFID actuator to be selected separately for the application. Its compact 37 × 26 × 18 mm technopolymer housing, lateral fixing, IP67 and IP69K protection and -25 to +70 °C ambient operating range make it suitable for demanding industrial environments.

Reliable Safety Monitoring for Industrial Automation
RFID safety sensors such as the Pizzato ST GD420N5 monitor movable machine guards without requiring physical contact between the sensor and actuator. When used with a compatible coded actuator, the sensor monitors its presence and communicates the guard condition through its electronic safety outputs, allowing the connected safety controller to initiate the required safe machine response when the guard is opened.
The ST G series is designed for modern machine builders requiring compact installation, dependable RFID guard monitoring and straightforward integration with industrial safety controls. Its symmetrical housing allows the same sensor to be used on guards opening in different directions simply by rotating the device, while the 22 mm mounting-hole spacing facilitates upgrades from compatible traditional magnetic safety sensor installations.
Typical Applications
- Machine guard doors and access panels.
- Industrial production and assembly machinery.
- Robotic cells and automated manufacturing systems.
- Packaging and processing equipment.
- Food and pharmaceutical production machinery.
- Safety interlocking systems using safety PLCs or safety modules.
