Murata AMR Magnetic Switch Sensors

Murata AMR Magnetic Switch Sensors are non-contact magnetic sensors of high sensitivity for use in a relatively low magnetic field. These sensors can detect a magnetic field in either a vertical or horizontal direction.

AMR sensor technology is used in Smartphones and Tablets. In an AMR sensor, the resistance of the sensor varies with the applied magnetic field. AMR sensors are more reliable and robust than Hall effect IC's or reed switches.
