ST HE311MK-H1TF Pizzato ST H series safety sensor

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.

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.
