The parking disc serves as a position sensor for detecting the neutral and parking position of the gear selector lever or transmission. The component is exposed to large temperature swings from -40 °C to 180 °C and therefore to extreme stresses.
The component is magnetised in multiple tracks in order to ensure a precise position detection. The magnet consists of a plastic-bonded neodymium iron boron compound on a polyphenylene sulphide (PPS) basis and it is injected directly into the steel part. As a means of corrosion protection, the steel then receives an organic coating. In order to be able to produce particularly efficiently, the plant is fully automated and also monitors all quality requirements of the magnetisation inline. This ensures that only perfect parts reach our customers.
