Structure and inner electrical connection
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2017 BMW X3, 2016 BMW X3, 2015 BMW X3, 2014 BMW X3, and 2013 BMW X3. However, it is still accessible from the selected car via links, so may be relevant.
The sensor contains 3 Hall elements fitted side by side in one housing. The signals of the first and 3rd Hal elements form the differential signal to determine the signal frequency and air gap to the multi-pole sensor gear. The temporal offset of the signal of the middle element to the differential signal allows detection of rotation to the right or left.
