ST GD420N6-G1T Pizzato ST G series safety sensor

Why Choose the Pizzato ST GD420N6-G1T ST G Series Safety Sensor?

The Pizzato ST GD420N6-G1T is a compact RFID safety sensor with high-level 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 coded RFID detection with electronic safety outputs to provide dependable machine guarding and safety interlocking in automated production environments.

The ST GD420N6-G1T provides two safety inputs IS1–IS2, two safety outputs OS1–OS2, one signalling output O3 and one programming input I3. Its high-level coded G1T actuator provides individual RFID recognition for enhanced protection against manipulation, while the safety inputs allow integration into compatible series-connected safety architectures.

Operating from a 24 V DC supply, this N6 version features an integrated 6 m PVC cable and uses the SM G1T high-level coded actuator. The compact G-style actuator measures 37 × 26 × 18 mm, uses lateral fixing and provides an approximately 11 mm actuation distance. IP67 and IP69K protection and an ambient operating range of -25 to +70 °C make the sensor suitable for demanding industrial applications.

Key Advantages

• Non-contact RFID safety sensing for reliable machine guard and access monitoring.
• SM G1T high-level coded actuator provides individual RFID recognition and enhanced protection against manipulation.

Reliable Safety Monitoring for Industrial Automation

RFID safety sensors such as the Pizzato ST GD420N6-G1T monitor movable machine guards without requiring physical contact between the sensor and actuator. When the high-level coded actuator moves outside the permitted detection zone, the electronic safety outputs change state so that the connected safety module or safety PLC can initiate the required safe machine response.

The ST G series combines compact construction with coded RFID technology and flexible electrical integration. Its symmetrical housing can be used on guards opening in different directions by changing the sensor orientation, while the 22 mm mounting-hole spacing has been designed to facilitate 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.
• Machining centres and automated machine tools.
• Packaging, food and pharmaceutical processing equipment.
• Safety interlocking systems using safety PLCs or safety modules.
