ST DD420N5-D0T Pizzato ST D series safety sensor

Why Choose the Pizzato ST DD420N5-D0T ST D Series Safety Sensor?

The Pizzato ST DD420N5-D0T is a non-contact RFID safety sensor with actuator designed for monitoring guards, access doors and other protective devices on industrial machinery. Part of the Pizzato ST D series, it uses coded RFID technology to provide reliable electronic guard detection without the mechanical contact and associated wear of conventional electromechanical safety switches.

The ST DD420N5-D0T is supplied with a D0T low-coded RFID actuator and uses the ST D series 420 configuration, providing two safety inputs IS1 and IS2, two safety outputs OS1 and OS2, one signalling output O3 and one programming input I3. This comprehensive I/O arrangement supports flexible integration into compatible machine safety and automation architectures.

Operating from a 24 V DC supply, this configuration features a 5 m integrated cable for convenient connection within industrial machinery. Its robust technopolymer construction and IP67 / IP69K protection make the ST DD420N5-D0T well suited to demanding machinery, production equipment and applications involving frequently operated protective guards.

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 physical contact between the sensor and actuator. The coded RFID actuator is detected electronically, allowing the machine safety system to determine whether the associated protective guard is in the required position before hazardous machine functions are permitted.

The non-contact operating principle is particularly useful on machinery with frequently operated guards because there are no mechanically operated switching contacts between the sensor and actuator. Combined with dedicated safety inputs and outputs, signalling functionality, a programming input and a 5 m integrated cable, the ST DD420N5-D0T provides a versatile solution for integrating electronic guard monitoring into modern industrial machinery.

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.
