The OHD Thermal Guard is developed for thermal problem countermeasures
Its unique proprietary design features a magnet and a temperature-sensing soft ferromagnetic substance called ThermoriteR
The material’s magnetic flux density decreases as the temperature increases turning it into a paramagnetic substance at the Curie temperature.High reliability for on/off operations High-speed response Long operational life Excellent environmental durability Compatibility with extremely low (0.1 mW or lower) signals to high power (6 W) levels Extremely simple circuit design Compact， light and easy to handle Dust， explosion and corrosion-proof Wide range of operating temperatures available in 5℃ increments from +30℃ to +130℃ Applications Typical applications include atmospheric temperature detection and overheating monitoring of power transistors， power modules， room heaters， hot gas heaters， PPCs， amplifiers， motors， HDDs， FDDs and other general appliances.
