Product Details

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 Thermorite®. 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°C increments from +30°C to +130°C
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.
