ST DD420M0.1-L1T Pizzato ST D series safety sensor

Why Choose the Pizzato ST DD420M0.1-L1T ST D Series Safety Sensor?

The Pizzato ST DD420M0.1-L1T is a compact, non-contact RFID safety sensor designed for monitoring guards, doors and other protective devices on industrial machinery. As part of the Pizzato ST D series, it uses RFID technology and a digitally coded actuator to provide reliable safety monitoring without the mechanical wear associated with conventional electromechanical safety switches.

Designed for demanding machine safety applications, the ST DD420M0.1-L1T features redundant electronics and can support safety systems up to PL e, Category 4 and SIL 3 when correctly integrated. Its configuration provides two safety inputs, two safety outputs, one signalling output and one programming input, enabling flexible integration and series connection with compatible Pizzato safety devices.

The sensor operates from a 24 V DC supply and is supplied with a 0.1 m cable and M12 connector with the connection exiting from the right-hand side of the technopolymer housing. The supplied SM L1T high-coded actuator provides a 12 mm actuation distance, while IP67 and IP69K protection makes the assembly suitable for demanding industrial environments.

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. The coded actuator is detected electronically, allowing the safety system to determine whether the protective guard is correctly positioned before hazardous machine operation is permitted.

The non-contact operating principle is particularly useful on machines with frequent operating cycles because there are no mechanical switching contacts between the sensor and actuator. ST D series sensors can also be connected in series with compatible Pizzato safety devices, providing flexible protection for machinery with multiple access points while supporting high safety performance levels.

Typical Applications

• Machine guard and access door monitoring.
• Industrial automation equipment.
• Packaging and production machinery.
• Robotic cells and automated manufacturing systems.
• Material handling and conveyor systems.
• Machine tools and processing equipment.
• Safety enclosures and protective guarding.
• OEM machinery and automated production lines.
