Hall Effect devices are temperature-compensated magnetic field sensing products. They are best suited for extremely harsh environments for sensing motion such as under-the-hood automotive and heavy industrial machinery applications, including robotics where identification of objects and or counting rotations of gears is required.
The basic Hall element relies on a magnetic field in order to sense motion. The principle is based on the Hall effect, discovered more than 100 years ago by Edwin Herbert Hall. This effect is the small electrical potential created when a stationary magnetic field is placed perpendicular to a current-carrying conductor.
TT Optek offers a range of bi-polar, ratiometric and uni-polar Hall Effect Magnetic Sensors including Military Qualified products.
