描述

The ZMID5202 is an inductive position sensor IC with PWM, used for absolute rotary and linear motion sensing in automotive applications. The ZMID5202 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 ZMID5202 is fully qualified to automotive standards AEC-Q100, grade 0 up to 150°C ambient temperature.
