Why Choose the Pizzato ST GD420N10-D1T ST G Series Safety Sensor?
The Pizzato ST GD420N10-D1T is a high-performance RFID non-contact safety sensor designed for reliable machine guarding, safety interlocking and industrial automation applications. Part of the Pizzato ST G series, it uses RFID transponder technology and redundant electronics to provide dependable monitoring of movable guards, doors and access points without mechanical contact.
The ST GD420N10-D1T provides 2 safety inputs (IS1–IS2), 2 safety outputs (OS1–OS2), 1 signalling output (O3) and 1 programming input (I3). This flexible architecture supports series connection with compatible safety devices and integration with safety modules or safety PLCs, while the programmable functionality provides additional flexibility for sophisticated machine safety systems.
Operating from a 24 V DC supply, this cable-connected sensor is paired with the SM D1T high-level coded actuator. The actuator provides an 11 mm actuation distance and a versatile front and lateral fixing arrangement. With IP67 / IP69K protection and an operating temperature range of -25 °C to +70 °C, the ST GD420N10-D1T is engineered for dependable service in demanding industrial environments.

Reliable Safety Interlocking for Industrial Machinery
RFID safety sensors such as the Pizzato ST GD420N10-D1T monitor movable guards electronically without requiring mechanical contact between the sensor and actuator. The high-level coded actuator is uniquely identifiable by the associated sensor, helping prevent substitution with another actuator and providing a high degree of protection against manipulation of the safety interlock.
The ST G series uses redundant electronics and can achieve safety levels up to PL e and SIL 3 when correctly incorporated into a suitable safety system. Its two safety inputs and two safety outputs also allow series connection with compatible Pizzato safety devices, helping machine builders create efficient safety chains while retaining reliable guard monitoring and automation integration.
Typical Applications
- Machine guard and safety-door monitoring.
- Industrial safety interlocking systems.
- Packaging and production machinery.
- Automated assembly and manufacturing equipment.
- Conveyor and material handling systems.
- Food, pharmaceutical and process machinery.
