Why Choose the Pizzato ST HD511MK-H1T Safety Sensor?

The Pizzato ST HD511MK-H1T 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 robust construction for demanding industrial safety applications. The ST HD511MK-H1T features an integrated M12 connector and a high-coded H1T actuator arrangement, providing reliable non-contact guard monitoring where protection against actuator substitution is important.

With 24 V DC operation, two safety outputs, one signalling output and an external device monitoring input, the ST HD511MK-H1T provides straightforward integration with industrial safety control systems. Its high-level coded actuator provides an actuation distance of approximately 11 mm.

Key Advantages

  • Compact RFID safety sensor designed for machine guarding.
  • High-level coded actuator technology helps reduce the risk of actuator substitution.
  • 11 mm actuation distance supports flexible guard installation.
  • 24 V DC operation for straightforward industrial safety integration.
  • Integrated M12 connector provides a practical industrial connection.
  • IP67 and IP69K protection for demanding industrial environments.

  • Pizzato ST H series RFID safety sensor.
  • ST HD511MK-H1T product configuration.
  • Non-contact RFID-coded detection technology.
  • 2 safety outputs OS1–OS2.
  • 1 signalling output O3.
  • 1 EDM input for external device monitoring.
  • 24 V DC operating supply.
  • Integrated M12 connector.
  • High actuator coding level with H1T actuator configuration.
  • Approximately 11 mm actuation distance.
  • Actuator dimensions of approximately 90 × 25 × 18 mm with lateral fixing.
  • Permanent magnet holding force is not provided.
  • Status LED indication for convenient sensor monitoring.

Reliable Safety Monitoring for Industrial Machinery

RFID safety sensors such as the Pizzato ST HD511MK-H1T 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. High-level RFID coding helps reduce the risk of unauthorised actuator substitution, while the non-contact design avoids mechanical wear associated with conventional safety switches. The EDM input also supports monitoring of connected external safety devices within an appropriate safety circuit.

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.
