ST GD420N2-E1T Pizzato ST G series safety sensor

Why Choose the Pizzato ST GD420N2-E1T ST G Series Safety Sensor?

The Pizzato ST GD420N2-E1T is a high-performance 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 actuator to provide dependable monitoring of movable guards, doors and protective access points without mechanical contact.

The ST GD420N2-E1T 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 architectures and allowing compatible safety devices to be incorporated into sophisticated safety control systems.

Operating from a 24 V DC supply, this version features a 2 m PVC cable and the SM E1T high-level coded actuator. The E-style actuator provides an extended 18 mm actuation distance, measures 40 × 50 × 16 mm and uses front fixing. With an operating temperature range of -25 °C to +70 °C and IP67 / IP69K protection, the ST GD420N2-E1T is engineered for demanding industrial environments.

Reliable Safety Interlocking for Industrial Machinery

RFID safety sensors such as the Pizzato ST GD420N2-E1T monitor movable machine guards electronically without requiring mechanical contact between the sensor and actuator. The high-level coded SM E1T actuator provides individual RFID identification, helping protect the safety interlock against actuator substitution or manipulation while maintaining reliable guard-position detection.

The ST G series is designed for machine builders and industrial automation engineers requiring dependable safety monitoring with flexible system integration. The programmable GD420 configuration combines dual safety inputs and outputs with signalling and programming functionality, while the large E-style actuator provides an extended 18 mm actuation distance for applications where additional sensing clearance and tolerance are beneficial.

Typical Applications

• Machine guard and safety-door monitoring.
• Industrial safety interlocking systems.
• Large or alignment-sensitive movable guards.
• Packaging and production machinery.
• Automated assembly and robotic cells.
• Conveyor and material handling systems.
