Why Choose the Pizzato ST HD311MK-E1T Safety Sensor?

The Pizzato ST HD311MK-E1T is a compact and reliable RFID safety sensor designed for monitoring movable guards, safety doors and access points on industrial machinery and automation systems. As part of the advanced Pizzato ST H series safety sensor range, it uses non-contact RFID technology to provide dependable guard-position detection for machine safety applications.

The ST H series combines coded RFID recognition with electronic safety outputs and a robust technopolymer housing. Its non-contact operating principle eliminates mechanical switching wear, making it well suited to machinery where guards are opened and closed frequently. The E1T configuration uses a high-coded actuator for applications requiring enhanced actuator identification.

The ST HD311MK-E1T operates from a 24 V DC supply and provides 2 safety inputs, 2 safety outputs and 1 signalling output. The MK configuration features an integrated M12 connector, while the E1T configuration uses a high-coded E-type actuator for non-contact guard monitoring.

Key Advantages

  • Compact RFID safety sensor designed for machine guarding applications.
  • High actuator coding level provides enhanced protection against unintended actuator substitution.
  • 24 V DC supply for straightforward industrial safety-system integration.
  • Non-contact RFID detection eliminates mechanical switching wear.
  • IP67 and IP69K protection for demanding industrial environments.
  • Integrated M12 connector supports convenient connection to compatible control equipment.

  • ST HD311MK-E1T model.
  • RFID non-contact detection technology.
  • 2 safety inputs IS1–IS2.
  • 2 safety outputs OS1–OS2.
  • 1 signalling output O3.
  • 24 V DC operating supply.
  • High actuator coding level.
  • E-type actuator for compatible ST H series safety sensors.
  • Integrated M12 connector.
  • Electronic safety switching without mechanical contacts.
  • Integrated status indication.
  • Technopolymer housing.
  • IP67 / IP69K protection.

Reliable Safety Monitoring for Industrial Automation

RFID safety sensors such as the Pizzato ST HD311MK-E1T monitor the position of machine guards without requiring mechanical contact between the sensor and its associated actuator. When the high-coded actuator moves away from the detection zone, the sensor changes its safety outputs so the connected safety control system can initiate the appropriate safety response.

The ST H series is designed for modern machine safety and industrial automation applications where reliable guard monitoring, electronic switching and resistance to environmental conditions are important. Its two safety inputs and two safety outputs support integration into compatible safety systems, while the signalling output provides additional guard-status information for machine control and diagnostics.

Typical Applications

  • Machine guards and protective doors.
  • Industrial automation and production machinery.
  • Safety interlocking systems.
  • Packaging and processing machinery.
  • Material handling and conveyor equipment.
  • Machine tools and manufacturing equipment.
  • Safety monitoring on movable access guards.
  • OEM machinery and automated production systems.
