Description
The IPS2200 is a magnet-free, inductive position sensor ICs that can be used for high-speed absolute position sensing in industrial, medical, and consumer applications. The IPS2200 uses the physical principle of eddy currents to detect the position of a simple metallic target that is moving above a set of coils, consisting of one transmitter coil and two receiver coils.
