Long life / excellent resistance to environment NEC Tokin thermal sensor uses reed switch as the switching device. Reed switch is a magnetism reacting device that has two fine reed shaped magnetic material as the switch contact that are fixed to keep an extremely small gap between each other. These switch contacts are sealed in a glass tube with inactive gas, thus having a superior dust proof, ignition proof and corrosion resistance property.Moreover, degradation due to metal fatigue is extremely small. The life time based on metal fatigue is 500000 on/off*1. (*1 Test data of the thermal reed switch TRS® under our standard testing condition)

Optional setting of operating temperature is possible / excellent temperature precision Thermal sensor is mainly consists of thermal magnetic material Thermorite®, permanent magnet and reed switch. (Thermorite is a ferromagnetic substance made of soft magnet. This material decreases the saturation magnetic flux density as temperature rises and turns into a paramagnetic substance at the curie temperature.) It is possible to change the operating temperature to a desired point when designing. To obtain precision sensitivity, optimization is made by selecting the material, shape, and dimension of the parts. Compared to bimetals that are used for the same application, it has the superior characteristics.     NT's TRS Bimetal(ref data) Temperature Tolerance 15 5 Minimum ON/OFF current 10A 50mA Life and endurance 5times*1 times Thermal Response twice as large as bimetals*2 - *1 TRS's data Under Our standard loading condition *2 Under our independent test
