Inductive Position Sensor IC

The ZMID5201 is an inductive position sensor IC with analog output, used for absolute rotary and linear motion sensing in automotive, industrial and consumer applications. The ZMID5201 uses the physical principles of induction in a wire loop and eddy currents to detect the position of a metallic 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 which depends on the position of the metallic target above the coils. After demodulating and processing the secondary voltages from the receiver coils, a signal representative of the metallic target’s position over the coils is obtained. The ZMID5201 is fully qualified to automotive standards AEC-Q100, grade 0 up to 150°C ambient temperature.
