Hall-Effect Sensor ICs 
As the world leader in Hall-effect sensor ICs, Allegro offers a broad
line of silicon-based products that serve many high-end applications
within automotive and industrial electronics.
Allegro's sensor ICs are based on Hall-effect technology, which allows
contactless sensing devoid of mechanical wear, sensing either an external
magnet or a ferrous object. Specifically, Hall-effect sensor ICs are used
for highly accurate gear-tooth sensing, direction detection, linear
sensing, speed sensing, position sensing and contactless switching.
