Austriamicrosystems’ AS5410 linear position sensor integrated circuit senses absolute position in automotive applications and provides the highest resolution position information available. According to the company, it is the first product of the world’s first fully featured 3-D Hall platform. The AS5410 sensor allows absolute position sensing of a simple two-pole magnet immediately after starting up the device without the need for a prior reference run within the application. Position sensing is possible over large mechanical travel distances even with very small magnets. For example, a travel distance of 40 mm (1.6 in) does not pose a problem for a small 4 x 4 x 3 mm (0.16 x 0.16 x 0.12 in) NeFeB magnet.
