ST GD420MP-G1T Pizzato ST G series safety sensor

Why Choose the Pizzato STGD420MP-G1T Safety Interlock Sensor?

The Pizzato STGD420MP-G1T is a high-reliability RFID safety interlock sensor designed for machine guarding, access control, and industrial automation safety applications. As part of the advanced Pizzato ST G series RFID safety sensor platform, it provides secure non-contact monitoring of safety doors and protective guards in modern automated machinery systems.

This model uses coded RFID actuator technology to ensure only the correct paired actuator enables machine operation, significantly reducing the risk of tampering or bypass attempts. It is widely used in OEM machinery, robotics, packaging systems, and industrial automation where high functional safety and compliance with PL e (ISO 13849-1) and SIL 3 (IEC 61508) are required.

The STGD420MP-G1T features a compact technopolymer housing with integrated M12 connector (MP version), designed for fast installation and reliable wiring in control panels. Its non-contact sensing technology eliminates mechanical wear, improves durability, and supports long service life in high-cycle industrial environments. {index=1}

Advanced Machine Safety with RFID Technology

The Pizzato STGD420MP-G1T uses RFID-coded actuator recognition to ensure that only a correctly paired actuator can enable machine operation. This significantly improves safety integrity in industrial environments by preventing unauthorized access.

Technical data for the ST G series confirms that G1T high-coding variants are intended for high-security applications where stronger tamper resistance and controlled access logic are required. The non-contact RFID system also supports high-cycle operation without mechanical degradation.

According to ST G series specifications, these sensors are suitable for integration into safety circuits up to PL e and SIL 3 when correctly implemented within a certified safety system architecture. ([turn0search1])
