ST DD311N10-D1T Pizzato ST D series safety sensor

Why Choose the Pizzato ST DD311N10-D1T ST D Series Safety Sensor?

The Pizzato ST DD311N10-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 actuator recognition 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, providing increased protection against manipulation and unauthorised actuator 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 DD311N10-D1T is designed for standard 24 V DC industrial safety systems and features an integrated 10 m PVC cable for direct electrical connection. It provides two safety inputs, two safety outputs and one signalling output, while the D1T actuator provides a nominal 12 mm actuation distance. Its durable technopolymer housing 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 DD311N10-D1T monitor 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 verify the position of the associated guard 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 DD311N10-D1T combines redundant safety channels with a practical 10 m connection cable, making it particularly suitable for larger machines and installations where the safety sensor is positioned some distance from the control enclosure.

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.
