ST GD420N2-E0T Pizzato ST G series safety sensor

Why Choose the Pizzato ST GD420N2-E0T ST G Series Safety Sensor?

The Pizzato ST GD420N2-E0T 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 large low-level coded actuator to provide dependable monitoring of movable guards, doors and protective access points without mechanical contact.

The ST GD420N2-E0T provides 2 safety inputs (IS1–IS2), 2 safety outputs (OS1–OS2), 1 signalling output (O3) and 1 programming input (I3). The programmable GD420 configuration provides flexible integration into modern machine safety architectures, including compatible series-connected safety devices and systems using safety modules or safety PLCs with OSSD inputs.

Operating from a 24 V DC supply, this version features a 2 m oil-resistant PVC cable and is paired with the SM E0T large low-level coded actuator. The E-style actuator provides an extended 18 mm actuation distance, measures 40 × 50 × 16 mm and uses front fixing. With IP67 / IP69K protection and an ambient temperature range of -25 °C to +70 °C, the sensor is suitable for demanding industrial environments.

Reliable Safety Interlocking for Industrial Machinery

RFID safety sensors such as the Pizzato ST GD420N2-E0T monitor movable machine guards electronically without requiring mechanical contact between the sensor and actuator. The large SM E0T actuator provides an 18 mm sensing distance, offering greater operating clearance than the standard, two-level and miniaturised actuator options while maintaining reliable RFID guard detection.

The ST G series is designed for machine builders and industrial automation engineers requiring compact installation, dependable safety monitoring and flexible system integration. The programmable GD420 architecture combines dual safety inputs and outputs with signalling and programming functionality, while the E-style actuator is particularly useful where a larger actuator and increased sensing distance are advantageous. As the E0T uses low-level coding, installation should follow the applicable ISO 14119 measures intended to prevent foreseeable bypassing of the safety device.

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.
