KEMET TRS™ Thermal Reed Switches

The TRS Thermal Reed Switch by KEMET 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.

Features

  • High reliability for on/off operations 
  • High-speed response 
  • Long operational life
  • Excellent environmental durability
  • Extremely simple circuit design
  • Compact, light and easy to handle
  • Dust, explosion and corrosion-proof
  • Wide range of operating temperatures available from -10°C to +130°C
  • Excellent temperature accuracy of ±2.5°C
  • UL and CSA approved for TRS5***BLRU 100V
  • UL approved for TRS5***BLRVU 200V
  • RoHS/REACH compliant

There are a lot of Reed Switches in the world. I know a guy whose last name is Reed and he switched from engineering to medicine. I call that the Medical Reed Switch, and while Dr. Reed is off saving lives, you can use KEMET’s TRS Thermal Reed Switches to monitor temperatures and save energy. The TRS is designed with a magnet and Thermorite, a proprietary ferromagnetic material that enables fast, precise, and reliable on/off operation.

KEMET offers TRS devices with switching temperatures from negative 10 to positive 130 degrees Celsius, with plus or minus 2.5 degree accuracy. Both make and break configurations are available, with power ratings up to 60.5W and voltage ratings up to 200V. TRS Thermal Reed Switches are compact, lightweight, and offered in axial, wire harness, case, and molded types for application versatility. They’re also dust, explosion, and corrosion proof, with UL and CSA approval on select products.
