ST GD420N2-L1T Pizzato ST G series safety sensor

Why Choose the Pizzato ST GD420N2-L1T ST G Series Safety Sensor?

The Pizzato ST GD420N2-L1T is a compact 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 miniature high-level coded actuator to provide dependable monitoring of movable guards, safety doors and protective access points without mechanical contact.

The ST GD420N2-L1T 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 supporting applications requiring interconnected safety devices, safety modules and safety PLCs.

Operating from a 24 V DC supply, this version features a 2 m oil-resistant PVC cable and the SM L1T miniature high-level coded actuator. The actuator provides an 11 mm actuation distance, measures just 53 × 16 × 7 mm and uses front fixing, making it particularly suitable for restricted installation spaces. The ST G housing operates from -25 °C to +70 °C and provides IP67 / IP69K protection.

Reliable Safety Interlocking for Industrial Machinery

RFID safety sensors such as the Pizzato ST GD420N2-L1T monitor movable machine guards electronically without requiring mechanical contact between the sensor and actuator. The high-level coded SM L1T actuator uses individual RFID identification, allowing the associated sensor to recognise its programmed actuator and helping protect the safety interlock against substitution or deliberate manipulation.

The miniature L-style actuator is particularly useful where guard dimensions or available installation space restrict the use of conventional actuators. Combined with the programmable GD420 architecture, dual safety inputs and outputs, dedicated signalling output and programming input, the ST GD420N2-L1T provides a versatile safety-interlocking solution for modern machinery and automated production equipment.

Typical Applications

• Machine guard and safety-door monitoring.
• Compact guards and space-restricted safety interlocks.
• Packaging and production machinery.
• Automated assembly and robotic cells.
• Conveyor and material handling systems.
• Food, pharmaceutical and process machinery.
