Why Choose the Pizzato ST HD311MK-H1T Safety Sensor?
The Pizzato ST HD311MK-H1T 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 coded non-contact RFID technology to provide dependable guard-position detection for machine safety applications.
The ST H series combines 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 high coding level provides enhanced actuator identification for safety-critical guarding applications.
The ST HD311MK-H1T operates from a 10–30 V DC supply and provides 2 safety inputs, 2 safety outputs and 1 signalling output. The MK configuration features an integrated M12 stainless steel connector, while the H1T configuration uses a high-coded H-type actuator with an actuation distance of 11 mm.

Reliable Safety Monitoring for Industrial Automation
RFID safety sensors such as the Pizzato ST HD311MK-H1T 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.
