Why Choose the Pizzato ST DD420N1-D1T ST D Series Safety Sensor?
The Pizzato ST DD420N1-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 PNP safety outputs to provide dependable machine safeguarding without the mechanical wear associated with conventional electromechanical safety switches.
The ST DD420N1-D1T provides two safety inputs IS1-IS2, two safety outputs OS1-OS2, one signalling output O3 and one programming input I3. This comprehensive I/O configuration supports integration into modern machine safety architectures, while the sensor is suitable for safety functions up to PL e and SIL 3 when correctly integrated into an appropriate safety system.
Operating from a 24 V DC supply, the ST DD420N1-D1T features a PVC cable connection and is supplied with a high-level coded D1T actuator. The actuator provides a 12 mm actuation distance and measures approximately 45 × 25 × 18 mm, with front and side fixing options. IP67 and IP69K protection and an operating temperature range of -25 °C to +70 °C make the sensor suitable for demanding industrial environments.

Reliable Safety Monitoring for Industrial Automation
RFID safety sensors such as the Pizzato ST D series monitor the position of movable guards by detecting a coded actuator without requiring physical contact between the sensor and actuator. This non-contact operating principle helps minimise mechanical wear while providing consistent switching performance in machinery where guards and access doors may be opened frequently.
The ST DD420N1-D1T combines dual safety inputs and outputs with a signalling output and programming input for flexible integration into compatible industrial safety systems. Its high-level coded actuator improves resistance to manipulation, while the PNP electronic outputs, status indication and robust environmental protection support reliable operation and straightforward diagnostics in modern automated machinery.
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 high-level coded non-contact safety interlocking.
