ST GD420N5-G1T Pizzato ST G series safety sensor

Why Choose the Pizzato ST GD420N5-G1T ST G Series Safety Sensor?

The Pizzato ST GD420N5-G1T is a compact and highly reliable RFID safety sensor with high-level coded actuator designed for non-contact monitoring of guards, doors and access points on industrial machinery. As part of the advanced Pizzato ST G series, it combines RFID actuator recognition with electronic safety outputs to provide dependable machine guarding and safety interlocking in automated production environments.

The ST GD420N5-G1T 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 high-level coded G1T actuator provides individual RFID recognition for enhanced protection against guard-system manipulation.

Operating from a 24 V DC supply, this N5 version features an integrated 5 m PVC cable and uses the compact SM G1T high-level coded actuator. The G-style actuator measures approximately 37 × 26 × 18 mm, uses lateral fixing with 22 mm hole spacing and provides an 11 mm actuation distance. IP67 and IP69K protection and a -25 to +70 °C ambient operating range make the sensor suitable for demanding industrial environments.

Reliable Safety Monitoring for Industrial Automation

RFID safety sensors such as the Pizzato ST GD420N5-G1T monitor movable machine guards without requiring physical contact between the sensor and actuator. When the high-level coded actuator moves outside the permitted sensing area, the safety outputs change state so that the connected safety controller can initiate the required safe machine response.

The ST G series is designed for processing and assembly plants, robotised production islands and machining centres where compact installation and reliable guard monitoring are required. High-level RFID coding means the sensor recognises its programmed actuator, while the safety inputs, safety outputs and programming input provide flexible integration with modern machine safety architectures.

Typical Applications

• Machine guard doors and access panels.
• Automated production and assembly machinery.
• Robotised cells and manufacturing islands.
• Machining centres and automated machine tools.
• Packaging and processing equipment.
• Safety interlocking systems using safety PLCs or safety modules.
