Why Choose the Pizzato ST HE820MP-H0TE ST H Series Safety Sensor?
The Pizzato ST HE820MP-H0TE is a high-performance RFID electronic safety interlock sensor with magnetic holding designed for reliable non-contact monitoring of guards, doors and access points on industrial machinery. Part of the Pizzato ST H RFID Safety Sensor Series, it combines transponder-based RFID detection with robust electronic safety technology for machine guarding, safety interlocking and industrial automation applications.
The ST HE820MP-H0TE uses electronic PNP switching and is suitable for safety functions up to Performance Level e and SIL 3 when correctly incorporated into an appropriate safety system. Its non-contact operating principle avoids mechanical interaction between the sensor and actuator, helping reduce wear while providing dependable guard position monitoring across repeated machine operating cycles.
The H0TE configuration uses a low-level coded RFID actuator with an actuation distance of approximately 11 mm and a permanent magnet providing approximately 25 N holding force. The MP version features an integrated M12 technopolymer connector, while status indication, an operating temperature range of -25 °C to +70 °C and robust environmental protection make it well suited to demanding industrial installations.

Reliable Safety Monitoring for Industrial Automation
RFID safety sensors such as the Pizzato ST HE820MP-H0TE monitor the position of machine guards by electronically recognising a coded transponder actuator without requiring mechanical contact between the sensor and actuator. This non-contact operating principle reduces mechanical wear while providing dependable guard monitoring throughout repeated opening and closing cycles in automated production machinery.
The ST HE820MP-H0TE combines RFID safety detection with approximately 25 N magnetic holding force, helping keep lightweight guards correctly positioned where vibration, recoil or air movement could otherwise cause unwanted movement. Its M12 connection, electronic PNP switching and high functional safety capability make it suitable for integration into modern machine safety controllers and OEM automation systems.
Typical Applications
- Industrial machine guard monitoring.
- Safety doors and movable access panels.
- Robotic cells and automated manufacturing systems.
- Packaging and processing machinery.
- Conveyor and material handling equipment.
