Why Choose the Pizzato ST DD420N15-D1T ST D Series Safety Sensor?
The Pizzato ST DD420N15-D1T is a robust RFID non-contact safety sensor with actuator designed for reliable monitoring of guards, doors and protective devices on industrial machinery. As part of the Pizzato ST D series, it combines coded RFID detection with electronic safety inputs and outputs to provide dependable machine safeguarding without the mechanical wear associated with conventional electromechanical safety switches.
The ST DD420 configuration provides two safety inputs, two safety outputs, one signalling output and one programming input, supporting flexible integration into modern industrial machine safety architectures. Its non-contact operating principle is particularly suited to machinery with frequent guard-opening cycles, while the ST D platform can support high-level safety functions when correctly incorporated into an appropriate safety control system.
Operating from a 24 V DC supply, the ST DD420N15-D1T features a 15 m pre-wired cable for installations requiring an extended connection between the safety sensor and control equipment. The supplied D1T high-level coded RFID actuator provides enhanced resistance to manipulation and an approximately 12 mm actuation distance, making this configuration suitable for demanding automated machinery and industrial guard-monitoring applications.

Reliable Safety Monitoring for Industrial Automation
RFID safety sensors such as the Pizzato ST D series monitor movable guards by detecting a coded actuator without requiring physical contact between the sensor and actuator. This eliminates mechanical switching wear and helps maintain consistent safety monitoring through frequent operating cycles, making the technology well suited to modern automated production machinery.
The ST DD420N15-D1T combines dual safety inputs and outputs with signalling and programming functionality for flexible integration into compatible safety controllers and machine automation systems. Its high-level coded D1T actuator helps protect against deliberate or accidental substitution, while the extended 15 m cable provides additional installation flexibility where the sensor is positioned away from the main control enclosure.
Typical Applications
- Machine guard and access-door monitoring.
- Automated production and assembly machinery.
- Packaging and processing equipment.
- Robotic cells and automated manufacturing systems.
- Conveyors and material handling equipment.
- Industrial machinery requiring extended-cable RFID safety interlocking.
