Inductive Position Sensor IC
ZMID5201/02/03 Datasheet
Description
The ZMID5201, ZMID5202, and ZMID5203 family of inductive position sensor ICs are used for absolute rotary or linear motion sensing in automotive, industrial, medical, and consumer applications. The ZMID520x uses the physical principles of induction in a wire loop and eddy currents to detect the position of an electrically conducting target that is sliding or rotating above a set of coils, consisting of one transmitter coil and two receiver coils.
The three coils are typically printed as copper traces on a printed circuit board (PCB). They are arranged such that the transmitter coil induces a secondary voltage in the receiver coils that depends on the position of the metallic target above the coils.
