AMR Sensors (Magnetic Sensors)Rotation Detection-High accuracy resonators Type-

Specialized for detecting rotations.
Stable output characteristics can be gained, so this type of magnetic switch achieves high accuracy detection of rotational displacements. Using two switches enables the sensing of the rotational direction.


Series Lineup


  • If the strength of a magnetic field is over a constant, the duty cycle of when the sensor is ON versus when it is OFF will be stabilized at around 50%.
    (In the case there are multiple sensors set up to discern the direction of rotation, the stability of the duty cycle is important.)


  • Rotation detection applications such as in gas and water meters
  • Applications where low current consumption is required, such as powering batteries
