ST DD420M0.2-D1T Pizzato ST D series safety sensor

Why Choose the Pizzato ST DD420M0.2-D1T ST D Series Safety Sensor?

The Pizzato ST DD420M0.2-D1T is a high-performance RFID non-contact safety sensor designed for reliable monitoring of guards, doors and protective devices on industrial machinery. As part of the Pizzato ST D series, it combines digitally coded RFID actuator detection with redundant electronic safety architecture to provide dependable machine safeguarding without the mechanical wear associated with conventional electromechanical safety switches.

The ST DD420 configuration provides two OS safety outputs, one signalling output, two IS safety inputs and one programming input, supporting flexible integration into modern machine safety systems. Compatible ST D sensors can be connected in series with other Pizzato safety devices, while the series is designed to support safety systems up to PL e, Category 4 and SIL 3 when correctly integrated.

The ST DD420M0.2-D1T is paired with the SM D1T high-level coded RFID actuator, providing a nominal 12 mm actuation distance. Each D1T actuator has a unique code and is associated with its specific sensor, providing enhanced protection against manipulation. The M0.2 connection configuration incorporates an M12 connection arrangement for convenient integration into industrial machine wiring.

Reliable Safety Monitoring for Industrial Automation

RFID safety sensors such as the Pizzato ST D series detect a digitally coded actuator without requiring physical contact between the sensor and actuator. This provides reliable monitoring of movable guards while eliminating mechanical switching wear, making the technology particularly suitable for automated machinery with frequent operating cycles or demanding environmental conditions.

The ST DD420M0.2-D1T uses a high-level coded D1T actuator with an individual RFID code. The associated sensor recognises its specific actuator, and replacement with another D1T actuator requires a new association procedure. Combined with redundant electronics, dual safety inputs and dual safety outputs, this provides a robust solution for modern machine safety systems requiring high resistance to manipulation.

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.
