ST DD420M0.3-D1T Pizzato ST D series safety sensor

Why Choose the Pizzato ST DD420M0.3-D1T ST D Series Safety Sensor?

The Pizzato ST DD420M0.3-D1T is a compact, non-contact RFID safety sensor designed for monitoring guards, doors and other protective devices on industrial machinery. As part of the advanced Pizzato ST D series, it uses RFID technology and a coded actuator to provide dependable safety monitoring without the mechanical wear associated with conventional electromechanical safety switches.

Designed for demanding machine safety applications, the ST DD420M0.3-D1T incorporates redundant safety 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, supporting flexible integration with machine safety controllers and compatible Pizzato safety devices.

The sensor operates from a 24 V DC supply and features a 0.3 m cable for convenient connection within industrial machinery. The D1T actuator configuration provides non-contact RFID guard detection, while the robust ST D series construction and high environmental protection make the sensor suitable for demanding automation and machine-building applications.

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 machine safety system to determine whether a protective guard is correctly positioned before hazardous machine functions are permitted.

The non-contact operating principle is particularly useful on machinery with frequent operating cycles because there are no mechanical switching contacts between the sensor and actuator. ST D series sensors also provide flexible electrical integration and can be used with compatible Pizzato safety devices to protect machinery with multiple guarded access points.

Typical Applications

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