Why Choose the Pizzato ST GD420N3-L1T ST G Series Safety Sensor?
The Pizzato ST GD420N3-L1T is a compact and reliable RFID safety sensor designed for non-contact monitoring of guards, doors and access points on industrial machinery. As part of the Pizzato ST G series, it combines coded RFID detection with electronic safety outputs to provide dependable machine guarding and safety interlocking in automated production environments.
The ST GD420N3-L1T incorporates two safety inputs IS1–IS2, two safety outputs OS1–OS2, a signalling output O3 and a programming input I3. This configuration supports integration with safety modules and safety PLCs while allowing multiple compatible sensors to be incorporated into sophisticated machine safety architectures.
Designed for a 24 V DC supply, the ST G series provides non-contact operation without the mechanical wear associated with conventional electromechanical guard switches. Its compact technopolymer housing, robust environmental protection and RFID operating principle make the ST GD420N3-L1T particularly suitable for modern industrial machinery where reliable guard detection, installation flexibility and resistance to contamination are important.
Key Advantages

Reliable Safety Monitoring for Industrial Automation
RFID safety sensors such as the Pizzato ST GD420N3-L1T monitor the position of movable machine guards without requiring physical contact between the sensor and actuator. When the RFID actuator moves outside the permitted sensing area, the safety outputs change state so that the connected safety controller can initiate the required safe machine response.
The ST G series is designed for modern machine builders and automation engineers requiring compact, electronically coded guard monitoring. Its safety inputs and outputs allow straightforward integration into automated safety systems, while non-contact operation helps reduce mechanical wear and maintenance compared with traditional tongue-operated safety switches.
Typical Applications
- Machine guard doors and access panels.
- Automated production and assembly machinery.
- Robotic cells and enclosed automation systems.
- Packaging and processing equipment.
- Food and pharmaceutical production machinery.
- Safety interlocking systems using safety PLCs or safety modules.
