ST GD420N5-D1T Pizzato ST G series safety sensor

Why Choose the Pizzato ST GD420N5-D1T ST G Series Safety Sensor?

The Pizzato ST GD420N5-D1T is a compact and highly reliable RFID safety sensor with high-level coded actuator designed for non-contact monitoring of guards, doors and access points on industrial machinery. Part of the advanced Pizzato ST G series, it combines RFID actuator recognition with redundant safety electronics to provide dependable machine guarding and safety interlocking in modern automation systems.

The ST GD420N5-D1T provides two safety inputs IS1–IS2, two safety outputs OS1–OS2, one signalling output O3 and one programming input I3. The safety inputs and outputs allow compatible Pizzato safety devices to be incorporated into series-connected safety chains, while the high-level RFID coding helps protect the guard system against manipulation or substitution with an unauthorised actuator.

Operating from a 24 V DC supply, this N5 version uses an integrated 5 m PVC cable and is paired with the SM D1T high-level coded actuator. The standard D-style actuator provides fixing on two levels and an approximately 11 mm actuation distance, while IP67 and IP69K protection and a -25 to +70 °C ambient operating range support use in demanding industrial environments.

Reliable Safety Monitoring for Industrial Automation

RFID safety sensors such as the Pizzato ST GD420N5-D1T monitor movable machine guards without requiring mechanical contact between the sensor and actuator. When the coded actuator moves outside the permitted sensing area, the electronic safety outputs change state so that the connected safety controller can initiate the required safe machine response.

The ST G series uses redundant electronics and is designed for integration with safety modules or safety PLCs equipped for electronic safety outputs. Its compact symmetrical housing can be used on left- or right-opening guards, while series connectivity, high-level RFID coding and robust environmental protection make it particularly suitable for modern automated machinery with multiple guarded access points.

Typical Applications

• Machine guard doors and access panels.
• Industrial production and assembly machinery.
• Robotic cells and enclosed automation systems.
• Packaging and processing equipment.
• Food and pharmaceutical production machinery.
• Safety interlocking systems using safety PLCs or safety modules.
