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. A signal representative of the target’s 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 according to the automotive standard AEC-Q100 grade 0 (-40°C to 150°C ambient temperature). Three versions with different output interfaces are available: - ZMID5201: Analog output - ZMID5202: PWM digital output - ZMID5203: SENT digital output Available Support Renesas provides Application Modules that demonstrate ZMID520x position sensing, including rotary, arc, and linear applications.
