General Description
The chip can measure magnetic field components in two different orientation directions 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 differential 3D magnetic field measurement.
The differential measurement makes the AS5410 ideal for use in rough industrial position sensing applications that include not only dust, dirt or moisture but also unwanted magnetic stray fields.
