Why Choose the Pizzato ST HD420N5-H0T Safety Sensor?

The Pizzato ST HD420N5-H0T is a compact and reliable RFID-coded non-contact safety sensor from the Pizzato ST H series, designed for monitoring movable guards, safety doors and access points on industrial machinery. Its electronic RFID technology provides dependable guard position detection without mechanical switching contacts, making it suitable for modern machine safety and automation systems.

The ST H series combines coded RFID detection with a robust technopolymer housing for demanding industrial safety applications. The ST HD420N5-H0T uses a PVC cable connection and an H0T low-coded actuator arrangement, providing a practical solution for machine guarding where reliable non-contact detection is required.

With 24 V DC operation, two safety inputs, two safety outputs, one signalling output and one programming input, the ST HD420N5-H0T provides flexible integration with industrial safety control systems. Its H0T actuator configuration provides an actuation distance of approximately 11 mm.

Key Advantages

  • Compact RFID safety sensor designed for machine guarding.
  • Low-level coded actuator technology provides reliable coded guard detection.
  • 11 mm actuation distance supports flexible guard installation.
  • 24 V DC operation for straightforward industrial control integration.
  • PVC cable connection provides a practical solution for industrial installations.
  • IP67 and IP69K protection for demanding industrial environments.

  • ST HD420N5-H0T product configuration.
  • Non-contact RFID-coded detection technology.
  • 2 safety inputs IS1–IS2.
  • 2 safety outputs OS1–OS2.
  • 1 signalling output O3.
  • 1 programming input I3.
  • 24 V DC operating supply.
  • PVC cable electrical connection.
  • Low actuator coding level with H0T actuator configuration.
  • Approximately 11 mm actuation distance.
  • Multicolour LED indication for convenient sensor status monitoring.
  • Compact construction for machine and guard installations.

Reliable Safety Monitoring for Industrial Machinery

RFID safety sensors such as the Pizzato ST HD420N5-H0T monitor the position of machine guards without requiring mechanical electrical contacts between the sensor and actuator. When the correctly coded actuator is detected, the safety system can confirm the guard position and permit the protected machine function to operate.

The ST H series is designed for machine builders and industrial automation engineers requiring dependable guard monitoring and straightforward integration with safety control systems. The non-contact design avoids mechanical wear associated with conventional safety switches, while the H0T coding provides a practical solution for applications where low-level actuator coding is appropriate.

Typical Applications

  • Industrial machine safety doors and access guards.
  • Automated production and processing machinery.
  • Robotic cells and guarded automation equipment.
  • Packaging and material handling systems.
  • Manufacturing machinery requiring non-contact guard monitoring.
  • OEM machine-building and industrial safety applications.
