ST GD420N10 Pizzato ST G series safety sensor

Why Choose the Pizzato ST GD420N10 ST G Series Safety Sensor?

The Pizzato ST GD420N10 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 provides electronic monitoring of movable guards, doors and protective access points without the mechanical contact associated with conventional safety switches.

The ST GD420N10 features 2 safety inputs (IS1–IS2), 2 safety outputs (OS1–OS2), 1 signalling output (O3) and 1 programming input (I3). This flexible electronic configuration allows the sensor to be incorporated into modern machine safety architectures and provides dedicated connections for safety control, status signalling and programmable functionality.

Operating from a 24 V DC supply, this ST G series version uses a PVC cable connection and durable technopolymer housing. Its IP67 / IP69K protection and operating temperature range of -25 °C to +70 °C make the sensor suitable for demanding industrial installations where reliable machine-guard monitoring is required.

Reliable Safety Interlocking for Industrial Machinery

RFID safety sensors such as the Pizzato ST GD420N10 monitor movable machine guards electronically rather than relying on mechanically operated contacts. When used with the appropriate compatible actuator, the sensor can determine the position of a protective guard and communicate its safety status to the machine control system, helping prevent hazardous operation when access protection is not correctly positioned.

The ST G series is designed for machine builders and industrial automation engineers requiring compact, reliable and flexible safety interlocking. The GD420 configuration combines dual safety inputs and outputs with dedicated signalling and programming connections, allowing the sensor to be incorporated into sophisticated machine safety circuits while supporting straightforward diagnostics and automation integration.

Typical Applications

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