Why Choose the Pizzato ST GD420M0.2-L1T ST G Series Safety Sensor?
The Pizzato ST GD420M0.2-L1T is a compact and highly reliable RFID safety sensor designed for non-contact monitoring of movable guards, doors and protective access points on industrial machinery. Part of the Pizzato ST G series, it combines RFID transponder technology with redundant electronic safety circuitry to provide dependable guard-position monitoring without the mechanical wear associated with conventional electromechanical safety switches.
The ST GD420M0.2-L1T provides two safety inputs IS1–IS2, two OSSD safety outputs OS1–OS2, one signalling output O3 and one programming input I3. Its programmable architecture supports integration with modern safety PLCs and safety modules, while the high-level coded L1T actuator uses an individual RFID code that must be associated with the sensor, helping protect the safety function against inappropriate actuator substitution.
Operating from a 24 V DC supply, this version features a 0.2 m PVC cable with M12 connector for convenient machine wiring. The miniaturised L1T actuator provides an 11 mm actuation distance, measures 53 × 16 × 7 mm and uses front fixing, making this configuration particularly suitable for compact guards where installation space is limited.

Reliable Safety Monitoring for Industrial Automation
RFID safety sensors such as the Pizzato ST G series detect compatible coded actuators without requiring physical contact between the sensor and moving guard. This non-contact operating principle reduces mechanical wear and provides reliable guard monitoring on machinery exposed to repeated movement, vibration and normal alignment tolerances.
The ST GD420M0.2-L1T combines redundant OSSD safety outputs with safety inputs and an I3 programming input for integration into modern industrial safety architectures. Its high-level coded L1T actuator has an individual code and must be associated with the sensor before operation; replacement actuators can be associated through the reprogramming procedure, after which the previously associated actuator is no longer recognised.
Typical Applications
- Machine guard and access-door monitoring.
- Compact guards with limited actuator mounting space.
- Automated manufacturing and assembly machinery.
- Packaging and processing equipment.
- Robotic cells and automated production lines.
- OEM machinery and industrial automation systems.
