ST GD420M0.1-G0T Pizzato ST G series safety sensor

Why Choose the Pizzato ST GD420M0.1-G0T ST G Series Safety Sensor?

The Pizzato ST GD420M0.1-G0T is a compact and highly reliable RFID safety sensor designed for non-contact monitoring of guards, doors and other movable protective devices on industrial machinery. As part of the Pizzato ST G series, it combines RFID transponder technology with redundant safety electronics for dependable integration into modern machine safety and automation systems.

This sensor operates from a 24 V DC supply and provides two safety inputs IS1-IS2, two safety outputs OS1-OS2, one signalling output O3 and one programming input I3. The programmable configuration supports flexible safety applications, while non-contact RFID operation helps minimise mechanical wear compared with conventional mechanically actuated safety switches.

The ST GD420M0.1-G0T features a cable with M12 connector and uses the SM G0T standard low-level coded actuator. This actuator provides an 11 mm actuation distance and measures 37 × 26 × 18 mm with lateral fixing. The robust technopolymer ST G housing provides IP67 and IP69K protection, making the assembly suitable for demanding industrial environments.

Reliable Non-Contact Machine Safety

RFID safety sensors such as the Pizzato ST G series monitor the position of movable machine guards without requiring direct mechanical contact between the sensor and actuator. The ST GD420M0.1-G0T monitors its safety inputs and the position of the RFID actuator before enabling its safety outputs, providing dependable guard status information to the machine safety control system.

The non-contact design reduces mechanical wear and provides greater tolerance to normal guard movement than many conventional mechanically actuated switches. Its symmetrical compact housing can be orientated to suit different installations, while the 22 mm mounting hole spacing makes the ST G series particularly useful when upgrading machinery from traditional magnetic safety sensors to RFID technology.

Typical Applications

• Machine guard and access door monitoring.
• Industrial automation and production machinery.
• Packaging and processing equipment.
• Automated assembly systems.
• Robotic cells and guarded manufacturing areas.
• Conveyor and material handling machinery.
• Food and beverage processing equipment.
• OEM machinery and industrial safety systems.
