Magnetic Displacement

Panasonic magnetic position sensing using Anisotropic Magneto-Resistive (AMR) sensors is becoming a popular method of implementing a non-contacting location of motional objects. By affixing a magnet or sensor element to a angular or linear moving object with its complementary sensor or magnet stationary, the relative direction of the resulting magnetic field can be quantified electronically. By utilizing multiple sensors or magnets, the capability of extended angular or linear position measurements can be enhanced.
