ST GD420N2-D0T Pizzato ST G series safety sensor

Why Choose the Pizzato ST GD420N2-D0T ST G Series Safety Sensor?

The Pizzato ST GD420N2-D0T is a compact and highly reliable 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 coded actuator to provide dependable monitoring of movable guards, doors and protective access points without mechanical contact.

The ST GD420N2-D0T 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, providing flexible integration into modern machine safety circuits and allowing compatible ST series sensors to be incorporated into series-connected safety architectures.

Operating from a 24 V DC supply, this version features a 2 m oil-resistant PVC cable and is paired with the SM D0T low-level coded actuator. The D-style actuator provides an 11 mm actuation distance, measures 45 × 25 × 18 mm and uses fixing on two levels. The ST G series also provides IP67 / IP69K protection, making it suitable for demanding industrial environments.

Reliable Safety Interlocking for Industrial Machinery

RFID safety sensors such as the Pizzato ST GD420N2-D0T monitor movable guards electronically without requiring mechanical contact between the sensor and actuator. The sensor recognises the compatible low-level coded D0T actuator when it enters the sensing area, allowing the machine safety system to determine whether the monitored guard is correctly positioned before hazardous machine functions are permitted.

The ST G series is designed for machine builders and industrial automation engineers requiring compact installation, dependable safety monitoring and flexible system integration. Its symmetrical housing and standard 22 mm fixing pattern simplify installation, while the programmable GD420 architecture and series-connection capability support modern safety PLC and safety-module applications.

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.
• Food, pharmaceutical and process machinery.
