ST DD310N3-D1T Pizzato ST D series safety sensor

Why Choose the Pizzato ST DD310N3-D1T ST D Series Safety Sensor?

The Pizzato ST DD310N3-D1T is a robust RFID safety sensor designed for contactless monitoring of movable guards, access doors and protective devices on industrial machinery. As part of the advanced Pizzato ST D series, it combines RFID sensing technology with redundant electronic safety inputs and outputs to provide dependable machine safeguarding in demanding automation environments.

This model uses a high-level coded D1T RFID actuator, with individually coded actuators providing increased protection against manipulation and unauthorised substitution. Contactless detection eliminates mechanical contact between the sensor and actuator, reducing wear and supporting reliable operation on machinery with frequent guard movements. The ST D series can support safety systems up to PL e, Category 4 and SIL 3 when correctly integrated into a suitable safety architecture.

The ST DD310N3-D1T operates from a 24 V DC supply and features an integrated 3 m PVC cable for direct electrical connection. It provides two safety inputs, two safety outputs and one signalling output, while the D1T actuator offers a 12 mm actuation distance. Its technopolymer housing, -25 °C to +70 °C operating range and IP67 / IP69K protection make it well suited to demanding industrial environments.

Reliable RFID Protection for Machine Guards

RFID safety sensors such as the Pizzato ST DD310N3-D1T monitor the position of machine guards without requiring mechanical contact between the sensor and actuator. The high-level coded D1T actuator is electronically recognised by the sensor, allowing a compatible safety control system to determine whether the associated guard is correctly positioned before hazardous machine movement is permitted.

The ST D series is designed for industrial safety applications where reliability, resistance to manipulation and flexible installation are important. The ST DD310N3-D1T combines two safety inputs, two safety outputs and a signalling output with a practical 3 m PVC connection cable, making it suitable for integration with compatible safety modules, safety PLCs and industrial machine control systems.

Typical Applications

• Machine guard and access door monitoring.
• Packaging and production machinery.
• Automated assembly equipment.
• Robotic cells and perimeter guarding.
• Food and beverage processing machinery.
• Material handling and conveyor systems.
