Why Choose the Pizzato ST GD420N2-T8 ST G Series Safety Sensor?
The Pizzato ST GD420N2-T8 is an extended-temperature RFID non-contact safety sensor designed for machine guarding, safety interlocking and industrial automation applications. Part of the Pizzato ST G series, it provides dependable electronic monitoring of movable guards, safety doors and protective access points without relying on mechanically operated contacts.
The ST GD420N2-T8 provides 2 safety inputs (IS1–IS2), 2 safety outputs (OS1–OS2), 1 signalling output (O3) and 1 programming input (I3). Operating from a 24 V DC supply, the GD420 architecture provides the safety and signalling connections required for integration with modern machine safety controllers and compatible automation systems.
The defining feature of this T8 version is its extended ambient operating temperature range of -35 °C to +85 °C, compared with the standard ST G range of -25 °C to +70 °C. The N2 configuration provides a 2 m PVC cable, while the robust technopolymer housing offers IP67 protection according to EN 60529 and IP69K protection according to ISO 20653, making the sensor well suited to demanding industrial environments.

Reliable Safety Interlocking for Industrial Machinery
RFID safety sensors such as the Pizzato ST GD420N2-T8 are designed to monitor the position of movable machine guards electronically and without mechanical contact between the sensor and its associated actuator. This non-contact operating principle reduces mechanical wear and makes the ST G platform particularly suitable for machinery where guards are opened and closed frequently.
The T8 configuration extends the permitted ambient temperature range to -35 °C to +85 °C, making this model particularly useful for machinery exposed to temperatures outside the standard ST G operating range. Combined with dual safety inputs, dual safety outputs, dedicated signalling and programming connections and robust IP67 / IP69K environmental protection, the ST GD420N2-T8 provides a versatile safety sensing solution for demanding automated equipment.
Typical Applications
- Machine guard and safety-door monitoring.
- Industrial safety interlocking systems.
- Machinery exposed to extended ambient temperature ranges.
- Automated production and assembly equipment.
- Packaging and processing machinery.
- Conveyor and material handling systems.
