inductive position sensor ic ZMID5201/ - 02/ - 03 datasheet ? 2017 integrated device technology, inc . 1 april 28, 2017 description the ZMID5201 , zmid5202, and zmid5203 ics are a family of i nductive position sensors, used for absolute rotary and 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 transmitte r 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 me tallic target above the coils. a signal representative of the targets position over the coils is obtained by demodulating and processing the secondary voltages from the receiver coils . the target can be any kind of metal, such as aluminum, steel or a pcb with a printed copper layer. the ZMID5201/ - 02 - /03 ics are fully qualified to the automotive stan dard aec - q 100, grade 0 from - 40c up to 150c ambient temperature. three versions with different output interfaces are available: ?
