Magnetic field sensors are a contact- and wear-free means of
measuring the position of machine parts and products. A new generation of Hall
sensors is now making the process even more precise and free of interference.
Magnetic field sensors are used to measure the position of
machine parts and products with zero contact and zero wear – in a modern car,
around 100 of such sensors are busy monitoring safety belt buckles and door
locks, registering pedal positions, or are used for ABS, EPS, and engine
control. They are cost-effective and robust, however, these conventional
sensors generally measure only the magnitude of the magnetic field
perpendicular to the chip surface.
