Pizzato ST GD420N1-G1T ST G series RFID safety sensor with 24 V DC supply, 1 m PVC cable, two safety inputs, two safety outputs, high-level coded standard actuator, 11 mm actuation distance and IP67/IP69K protection for industrial machine guarding.
Why Choose the Pizzato ST GD420N1-G1T ST G Series Safety Sensor?
The Pizzato ST GD420N1-G1T is a robust RFID non-contact safety sensor designed for reliable machine guarding, safety interlocking and industrial automation applications. Part of the Pizzato ST G series, it combines electronic RFID detection with a high-level coded actuator to provide dependable monitoring of movable guards, doors and access points without mechanical contact.
The ST GD420N1-G1T provides 2 safety inputs (IS1–IS2), 2 safety outputs (OS1–OS2), 1 signalling output (O3) and 1 programming input (I3). This flexible I/O arrangement supports integration into modern machine safety architectures and enables multiple sensors to be incorporated into automated safety systems.
Operating from a 24 V DC supply, the sensor uses an oil-resistant PVC cable for electrical connection and is paired with a high-level coded standard G actuator. The actuator has an 11 mm actuation distance, while the sensor's IP67 / IP69K protection and -25 °C to +70 °C operating temperature make the assembly suitable for demanding industrial environments.
Key Advantages

Reliable Safety Interlocking for Industrial Machinery
RFID safety sensors such as the Pizzato ST GD420N1-G1T monitor the position of movable machine guards without requiring mechanical contact between the sensor and actuator. When the correctly coded actuator enters the sensing area, the electronic safety system can verify the guard condition and provide the appropriate safety outputs to the machine control system.
The ST G series is designed for machine builders and industrial automation engineers requiring dependable guard monitoring with flexible electrical integration. High-level RFID coding helps reduce the risk of deliberate or accidental bypassing, while the safety inputs, outputs and programmable functionality support sophisticated safety architectures and series-connected installations.
