Why Choose the Pizzato ST DD420N1-D0T ST D Series Safety Sensor?

The Pizzato ST DD420N1-D0T 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 to detect a compatible coded actuator electronically, providing dependable machine guard monitoring without the mechanical contact associated with conventional electromechanical safety switches.

Designed for industrial machine safety applications, the ST DD420N1-D0T belongs to Pizzato's ST range of electronic safety sensors and is intended for integration into modern safety control architectures. The non-contact operating principle makes the ST D series particularly suitable for machinery with frequently opened guards, where reduced mechanical wear, reliable detection and straightforward installation are important.

The ST D series operates from a 24 V DC supply and uses electronic safety inputs and outputs for integration with compatible safety control equipment. The ST DD420N1-D0T combines compact construction with coded RFID detection, making it a practical solution for machine builders and automation engineers requiring dependable monitoring of movable guards and protective access points.

Key Advantages

  • Compact non-contact RFID safety sensor for industrial guard monitoring.
  • RFID technology enables coded actuator detection without mechanical contact.
  • Designed for integration into modern industrial machine safety systems.
  • Electronic safety architecture provides dependable guard status monitoring.
  • Non-contact operation reduces mechanical wear compared with conventional safety switches.
  • Suitable for machinery with frequently operated guards and access doors.
  • Compact design supports installation where mounting space is limited.
  • Part of the established Pizzato ST range of industrial safety products.

Key Features

  • Pizzato ST D series safety sensor.
  • Non-contact RFID operating principle.
  • 24 V DC supply for industrial safety applications.
  • Electronic safety inputs and outputs.
  • Coded actuator detection for machine guard monitoring.
  • Compact sensor construction for machinery installations.
  • Designed for movable guard and access door monitoring.
  • Suitable for industrial automation and OEM machinery.

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. A compatible 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. This helps minimise mechanical wear while providing machine builders with a compact electronic solution for integrating guard monitoring into modern industrial automation and safety systems.

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.
