ST DD420N3-D0T Pizzato ST D series safety sensor

Why Choose the Pizzato ST DD420N3-D0T ST D Series Safety Sensor?

The Pizzato ST DD420N3-D0T is a non-contact RFID safety sensor with actuator designed for monitoring guards, access doors and other protective devices on industrial machinery. Part of the Pizzato ST D series, it uses RFID technology to provide reliable guard position detection without the mechanical contact and associated wear of conventional electromechanical safety switches.

This configuration is supplied with a D0T low-coded actuator and provides two PNP safety outputs for integration with compatible machine safety equipment. The ST D series operates from a 24 V DC supply and uses electronic safety architecture to provide dependable non-contact monitoring for automated machinery and industrial safety applications.

The ST DD420N3-D0T features a 3 m integrated cable exiting from the right-hand side of the sensor, providing convenient wiring where additional connection length is required. Its robust technopolymer construction and ST D series environmental protection make it suitable for demanding machinery, production equipment and applications involving frequently operated protective guards.

Reliable RFID Safety Monitoring for Industrial Machinery

RFID safety sensors such as the Pizzato ST D series monitor movable machine guards without requiring physical contact between the sensor and actuator. The coded actuator is detected electronically, allowing the machine safety system to determine whether the associated protective guard is in the required position before hazardous machine functions are permitted.

The non-contact operating principle is particularly useful on machinery with frequently operated guards because it avoids mechanically operated switching contacts between the sensor and actuator. Combined with two PNP safety outputs and a 3 m integrated cable, the ST DD420N3-D0T provides a practical solution for integrating electronic guard monitoring into modern industrial machinery.

Typical Applications

• Industrial machine guard and access door monitoring.
• Packaging and production machinery.
• Robotic cells and automated manufacturing systems.
• Material handling and conveyor equipment.
• Machine tools and processing machinery.
• Safety enclosures and protective guarding.
• Assembly and automated production lines.
• OEM machinery and industrial automation systems.
