ST DD420M0.2-D0T Pizzato ST D series safety sensor

Why Choose the Pizzato ST DD420M0.2-D0T ST D Series Safety Sensor?

The Pizzato ST DD420M0.2-D0T is an industrial RFID non-contact safety sensor designed for reliable monitoring of guards, doors and protective devices on machinery. As part of the Pizzato ST D series, it combines coded RFID actuator detection with electronic safety outputs 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, giving machine builders flexible options for integrating the sensor into modern safety control architectures. Non-contact operation helps maintain consistent performance in applications involving frequent guard opening, vibration, contamination or repeated operating cycles.

The ST DD420M0.2-D0T is supplied with the SM D0T low-level coded actuator, providing a nominal 12 mm actuation distance. The M0.2 connection configuration provides a short cable with an M12 connector, while the compact technopolymer construction makes the sensor well suited to industrial automation, production machinery and safety guard monitoring.
