Why Choose the Pizzato ST HE311MK-H1TF Safety Sensor?

The Pizzato ST HE311MK-H1TF is an advanced RFID non-contact safety sensor with magnetic actuator holding designed for monitoring guards, doors and access points on industrial machinery. As part of the Pizzato ST H series RFID safety sensors, it combines coded RFID detection, electronic safety outputs and magnetic guard retention in a compact solution for modern machine safety and automation systems.

The ST H platform is designed to provide dependable guard-position monitoring without the mechanical wear associated with conventional contact-based safety switches. High-level RFID actuator coding provides reliable identification of the associated actuator and enhanced protection against manipulation, making the ST HE311MK-H1TF suitable for machinery where dependable access monitoring is an important part of the safety system.

Operating from a 24 V DC supply, the ST HE311MK-H1TF combines industrial electronic safety technology with the compact, robust construction of the Pizzato ST H range. Its MK connector configuration simplifies installation and replacement compared with permanently wired devices, while the integrated permanent magnet helps retain the associated guard in its closed position during normal machine operation.

Key Advantages

  • Non-contact RFID safety sensing minimises mechanical wear and supports long service life.
  • High-level coded actuator provides enhanced resistance to manipulation and unauthorised substitution.
  • Integrated magnetic holding helps retain machine guards in their closed position.
  • Electronic safety outputs enable integration with modern machine safety control systems.
  • MK connector configuration supports convenient installation, servicing and sensor replacement.
  • Compact ST H housing is designed for space-conscious machine guarding applications.
  • Robust construction supports use in demanding industrial automation environments.

Key Features

  • Pizzato ST H RFID safety sensor series.
  • 24 V DC operating supply.
  • RFID coded non-contact actuator detection.
  • High actuator coding level.
  • Electronic safety outputs for machine safety control.
  • Integrated permanent magnet for guard retention.
  • MK connector-based electrical connection.
  • Compact technopolymer ST H series housing.
  • Non-contact sensing reduces dependence on precise mechanical engagement.
  • Designed for connection to industrial safety controllers and safety PLC systems.

Reliable Safety Monitoring for Industrial Automation

RFID safety sensors such as the Pizzato ST HE311MK-H1TF monitor the position of movable machine guards without requiring mechanical contact between the sensing elements. When the correctly coded actuator is positioned within the sensor's operating range, the electronic safety system can recognise the closed-guard condition and use this information as part of the machinery's safety control architecture.

The ST H series combines coded RFID detection with magnetic guard retention, making it particularly useful where a guard needs both safety monitoring and assistance remaining closed during normal operation. Its connector-based design also supports efficient machine assembly and maintenance, making the ST HE311MK-H1TF well suited to OEM equipment, automated production systems and machinery incorporating multiple guarded access points.

Typical Applications

  • Machine guard and safety-door monitoring.
  • Automated production and assembly machinery.
  • Robot cells and robotic manufacturing systems.
  • Packaging and processing equipment.
  • Machining centres and industrial machine tools.
  • Conveyors and material handling systems.

Frequently Asked Questions

What is the Pizzato ST HE311MK-H1TF used for?

The ST HE311MK-H1TF is designed for non-contact safety monitoring of machine guards, doors and access points on industrial machinery and automated equipment.

What sensing technology does the ST HE311MK-H1TF use?

The sensor uses RFID coded non-contact technology to identify the associated actuator and monitor whether a machine guard is in the required position.

Does the ST HE311MK-H1TF provide magnetic guard holding?

Yes. The ST HE311MK-H1TF is part of the ST H range and incorporates permanent magnetic holding to help retain the associated actuator and machine guard in the closed position.

What electrical connection does the ST HE311MK-H1TF use?

The ST HE311MK-H1TF uses an MK connector configuration, providing a convenient detachable connection for machine installation, servicing and replacement.

Why use an RFID safety sensor instead of a mechanical safety switch?

RFID non-contact sensing eliminates mechanical engagement between the sensor and actuator, helping reduce wear while providing coded actuator recognition and reliable guard-position monitoring for modern industrial safety systems.
