Sensors TRS™ Series Thermal Reed Switch Overview Applications The TRS™ Series Thermal Reed Switch is a highly reliable, precise temperature-sensitive switch ideal for energy conservation. The TRS Series is composed of 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 its Curie temperature. The TRS Series has also been attested by the International Relay Association. 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. Benefits • • • • High reliability Long operational life Excellent temperature accuracy of ±2.5°C Wide range of operating temperatures available from +50°C to +130°C • Excellent environmental durability Ordering Information TRS 5- Series Reed Switch Type TRS 5 50 Operating Temperature (°C) 50 60 70 80 90 100 110 120 130 B LR Contact Type Shape Classification B = Break LR = L type with Tin © KEMET Electronics Corporation • P.O.
