Why Choose the Pizzato ST DD420M0.1 ST D Series Safety Sensor?
The Pizzato ST DD420M0.1 is a compact, non-contact RFID safety sensor designed for monitoring guards, doors and protective devices on industrial machinery. As part of the Pizzato ST D series, it combines RFID technology with redundant safety electronics to provide dependable guard monitoring without the mechanical wear associated with conventional electromechanical safety switches.
Designed for demanding machine safety applications, the ST DD420M0.1 features two safety inputs IS1-IS2, two safety outputs OS1-OS2, one signalling output O3 and one programming input I3. The programmable architecture provides flexible integration with machine safety systems and allows compatible Pizzato safety devices to be connected in series while maintaining a high level of functional safety.
The sensor operates from a 24 V DC supply and features a 0.1 m PVC cable with M12 connector, with the connection exiting from the right-hand side of its technopolymer housing. With IP67 and IP69K protection and an ambient operating temperature range of -25 to +70 °C, it is well suited to demanding industrial automation and machine-building environments. The ST DD420M0.1 is supplied as the sensor configuration without an actuator, allowing the appropriate compatible ST D series RFID actuator to be selected separately.

Reliable RFID Safety Monitoring for Industrial Machinery
RFID safety sensors such as the Pizzato ST D series monitor the position of movable machine guards without requiring mechanical contact between the sensor and actuator. A compatible coded RFID actuator is detected electronically, allowing the machine safety system to determine whether a protective guard is correctly positioned before hazardous machine functions are permitted.
The non-contact operating principle makes the ST D series particularly suitable for machinery with frequent operating cycles because there are no mechanical switching contacts between the sensor and actuator. Compatible ST D sensors can also be connected in series, providing a flexible solution for machinery with multiple guarded access points while supporting high safety performance levels.
