●AMR Sensor A sensor that utilizes the magnetoresistance effect of ferromagnetic materials, where the resistance value changes according to the magnetic field strength. It has sensitivity in low magnetic fields, a wide operating temperature range, excellent frequency characteristics, and can be used in harsh environments where optical methods are difficult. There is also a high-resistance type of AMR that takes advantage of the benefits of magnetoresistive elements in the lineup. ●G-GMR Sensor A sensor that utilizes the giant magnetoresistance effect of a granular structure where ferromagnetic materials are dispersed in a non-magnetic matrix, with resistance values changing according to the magnetic field strength. It has a wide sensitivity range and shows a greater resistance change rate than AMR.
