Thermal Sensors TRS Thermal Reed Switch Overview Applications The TRS Thermal Reed Switch is a highly reliable, precise temperature-sensitive switch ideal for energy conservation. 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. Typical applications include temperature detection.

Thermal Sensors TRS Thermal Reed Switch Overview Applications The TRS Thermal Reed Switch is a highly reliable, precise temperature-sensitive switch ideal for energy conservation. 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. Typical applications include temperature detection and overheat monitoring of electric appliances, heat-retention heater control for rice cookers, defrost for air conditioners and vending machines, roll heater temperature control for copying machines, radiator water temperature detection for automotive electric fan control. These products have also been attested by the International Relay Association.
