Why Choose the Pizzato ST GD420N10-L1T ST G Series Safety Sensor?
The Pizzato ST GD420N10-L1T is a robust RFID non-contact safety sensor designed for machine guarding, safety interlocking and industrial automation applications. Part of the advanced Pizzato ST G series, it combines electronic RFID detection with a high-level coded miniature actuator to provide dependable monitoring of movable guards, doors and access points without mechanical contact.
The ST GD420N10-L1T provides 2 safety inputs (IS1–IS2), 2 safety outputs (OS1–OS2), 1 signalling output (O3) and 1 programming input (I3). This programmable configuration supports flexible integration into modern industrial safety circuits, including applications requiring interconnected safety devices and communication with safety controllers or automation systems.
Operating from a 24 V DC supply, this version features a 10 m PVC cable and is paired with the SM L1T high-level coded miniature actuator. The actuator provides an 11 mm actuation distance and measures just 53 × 16 × 7 mm with front fixing, making it particularly useful where installation space is limited. The sensor also provides IP67 / IP69K protection and operates from -25 °C to +70 °C.
Key Advantages
- Reliable RFID non-contact safety sensing for industrial machine guarding.
- High-level coded SM L1T actuator provides enhanced protection against interlock manipulation.

Reliable Safety Interlocking for Industrial Machinery
RFID safety sensors such as the Pizzato ST GD420N10-L1T monitor movable guards electronically without requiring mechanical contact between the sensor and actuator. The high-level coded SM L1T actuator uses an individually assigned RFID code, allowing the sensor to recognise its associated actuator and helping protect the safety interlock against unauthorised substitution or manipulation.
The ST G series uses redundant electronic architecture and can support safety performance up to PL e and SIL 3 when correctly integrated into an appropriate machine safety system. The GD420 configuration combines safety inputs and outputs with signalling and programmable functionality, while the miniature L-style actuator makes this version particularly suitable for compact guards and installations where available mounting space is restricted.
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.
