AMR Sensors (Magnetic Sensors)Usages and Applications

Here are ways opening/closing detection, position detection, rotation detection, and omnidirectional detection are each used and applied as applications of AMR sensors (magnetic switches).

Opening/Closing Detection

Application examples:

  • Laptops and tablets
  • Refrigerators
  • Door security alarms
  • Maintenance hatches
  • Digital video cameras
  • Dishwashers
  • Water heater control panels

Opening/Closing detection can be used in applications where a variety of opening and closing operations are required.

Position Detection

Application examples:

  • Cylinder switches
  • Electronic locks
  • Liquid level gauges
  • Microswitches

Position detection can be used in applications where operations need to be controlled.

Rotation Detection

Application examples:

  • Water heaters
  • Water meters
  • Speed meters
  • Jog dials
  • Gas meters
  • Tachometers
  • Anemometers
  • Trackball mice

Rotation detection can be used in applications where the number of rotations needs to be monitored or controlled.

Omnidirectional Detection

Application examples:

  • Replacements for reed switches
  • External magnetic field detection for various devices

Omnidirectional detection can be used for applications that require wide magnetic field detection, or magnetic field detection from multiple, unspecified directions.
