ST GD420N15-G1T Pizzato ST G series safety sensor

Why Choose the Pizzato ST GD420N15-G1T ST G Series Safety Sensor?

The Pizzato ST GD420N15-G1T is a robust RFID non-contact safety sensor designed for 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 standard actuator to provide reliable monitoring of movable guards, doors and access points without mechanical contact.

The ST GD420N15-G1T provides 2 safety inputs (IS1–IS2), 2 safety outputs (OS1–OS2), 1 signalling output (O3) and 1 programming input (I3). The GD420 configuration is programmable, giving machine builders flexible integration options for modern safety circuits, interconnected safety devices and industrial automation systems.

Operating from a 24 V DC supply, this version features a 15 m oil-resistant PVC cable and is paired with the SM G1T high-level coded standard actuator. The actuator provides an 11 mm actuation distance and measures 37 × 26 × 18 mm with lateral fixing. With IP67 / IP69K protection and an ambient operating temperature range of -25 °C to +70 °C, the sensor is engineered for demanding industrial environments.

Reliable Safety Interlocking for Industrial Machinery

RFID safety sensors such as the Pizzato ST GD420N15-G1T monitor movable machine guards electronically without requiring mechanical contact between the sensor and actuator. The high-level coded SM G1T actuator is individually recognised by its associated sensor, helping protect the safety interlock against actuator substitution while ensuring reliable detection of the guard position.

The ST G series is designed for machine builders and industrial automation engineers requiring dependable guard monitoring with flexible safety-system integration. The programmable GD420 configuration combines dual safety inputs and outputs with signalling and programming functionality, while the 15 m PVC cable provides additional installation flexibility on larger machines, production lines and automated equipment.

Typical Applications

• Machine guard and safety-door monitoring.
• Industrial safety interlocking systems.
• Packaging and production machinery.
• Automated assembly and robotic cells.
• Conveyor and material handling systems.
• OEM machinery and automated production lines.
