Thermal Sensors TRS Thermal Reed Switch, Screw Type Overview Applications The TRS Thermal Reed Switch is a highly reliable, precise Typical applications include radiator water detection and temperature-sensitive switch ideal for energy conservation. overheat detection for industrial and agricultural engines. The screw mounting package of TRS-P makes it easy to set up in the application, by just screwing it in the device that needs temperature detection or overheat monitoring. Its unique proprietary design features a magnet and a temperature-sensing soft ferromagnetic substance called Thermorite . The materials 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. Benefits High reliability for on/off operations Dust, explosion and corrosion-proof High-speed response Wide range of operating temperatures available Long operational life from 80C to +120C Excellent environmental durability Excellent temperature accuracy of 3C Extremely simple circuit design with the screw mounting RoHS/REACH compliant Compact, light, and easy to handle TRS-P1 Type TRS-P2 Type Built Into Tomorrow KEMET Electronics Corporation KEMET Tower One East Broward Boulevard SE0219 TRS-P 11/5/2021 1 Fort Lauderdale, FL 33301 USA 954-766-2800 www.kemet.comThermal Sensors TRS Thermal Reed Switch, Screw Type Ordering Information TRS 1- 80 M PR 001 Maximum Shape Series Opening/Closing Operating Temperature (C) Contact Type Lead Type Classification Power (W) TRS 1 = 10 W 80 = 80C 105 = 105C B = Break PR = P shape 001 = PT1/8 85 = 85C 110 = 110C M = Make PT screw 002 = PT3/8 90 = 90C 115 = 115C 95 = 95C 120 = 120C 100 = 100C Structures and Principles of Operation TM Thermal Reed Switches (TRS ) are temperature-sensing switches composed of a magnet and a temperature- TM sensing soft ferromagnetic substance called Thermorite .

Structures and Principles of Operation Thermal Reed Switches (TRS) are temperature-sensing switches composed of a magnet and a temperature-sensing soft ferromagnetic substance called Thermorite. This materials saturation magnetic flux density decreases as the temperature Temperature sensing ferrite Thermorite increases, and it turns into a paramagnetic substance at its Curie temperature. Our self-developed Themorite is temperature sensing ferrite utilizing Curie-temperature, where ferrites lose its magnetic property. Thermorite changes its magnetic property rapidly at Curie-temperature. Thermorite properties Features of Thermorite as temperature sensing material. Thermorite changes its magnetic property rapidly at its Curie temperature, providing quick response times. (1) Curie-temperature do not vary as time advances, because it depends on compounding ratio. The Curie temperature of Thermorite does not vary with time, as it is based on a compounding ratio. (2) Arbitrary shape available as ceramics. Thermorite is stable against moisture and hazardous gas. (3) Stable against moist or hazardous gas.

The reeds are switched on or off Inactive gas Contact Fe-Ni alloy reed by magnetic field of permanent magnet or magnet coil. Long lifetime, High environmental resistance because of protected contact by glass encasing. N S Reeds in glass tube become magnetized with SS NN NN magnetic field, and then two reeds contact and SS connect each other (switch on). And then magnetic field disappears, the reeds separate and disconnect KEMET Electronics Corporation KEMET Tower One East Broward Boulevard SE0219 TRS-P 11/5/2021 2 (switch off).
