Active Area – The surface of a Hall-effect sensor or transducer that is sensitive to magnetic field. For many integrated Hall ICs, the active area is beneath the package surface by a short distance (∼0.020″ or 0.5 mm), and may only be a few thousandths of an inch square (∼0.1 mm × 0.1 mm).
Air Gap – The distance from the face of a magnet to the face of a sensor housing.
Alnico – A permanent magnet material made primarily from aluminum, nickel, and cobalt. Alnico magnets have relatively low energy products, but offer high stability, especially over temperature.
