Structure and inner electrical connection
WARNING: This page does not describe the selected car, but rather 45 other vehicles, including the 2016 BMW M5, 2016 BMW 550i xDrive, 2016 BMW 550i, 2016 BMW 535i xDrive, and 2016 BMW 535i. 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.
