TRS™ and OHD™ Thermal Sensors
KEMET’s TRS and OHD thermal sensors are used to monitor temperature and maintain stable operation
Thermal sensors are used in a variety of applications and play an important role in maintaining stable operation in electronics by monitoring temperature. KEMET's TRS sensors are thermal reed switches and its OHD series are well-suited for thermal problem countermeasures and safety standard conformity. The unique proprietary design of both sensors features a magnet and 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. These products have also been attested by the International Relay Association.
Which Thermal Sensor to Choose?
TRS Thermal Reed Switch
The TRS thermal reed switch is a highly reliable, precise, temperature-sensitive switch ideal for energy conservation. This switch is offered in a variety of shape/mounting types from axial, wire harness, case, molded, and screw mounting to cover any application requiring temperature monitoring.
OHD Thermal Guard
Kemet's OHD thermal guard is developed for thermal problem countermeasures and safety standard conformity, which are becoming increasingly important for electronic devices.
