AS5410 3D-Hall Encoder absolute linear

The chip can measure magnetic fields components in all three dimensions and converts the magnetic field information into absolute, position information. The AS5410 supports absolute linear position measurement applications. Only a simple 2-pole magnet is required as the magnetic field source. Using two 3D-Hall cells allows both absolute as well as differenti.
