Magnetic sensor MR series

These products are magnetic sensors using AMR elements whose resistance varies according to the strength or direction of the magnetic field. Combination with a magnet permits non-contact rotation detection or position detection. These are magnetic switches that are built-in IC that output H/L digital signals based on magnetic field strength. Magnetic switches are being widely used for cylinder-position detection applications, rotation detection applications such as in gas and water meters, and opening/closing detection applications such as in single-lens reflex cameras, video cameras, and refrigerators.
