Abstract
More and more automotive applications require exact position sensing. Today resistive potentiometers are the most frequently used sensors. For reasons of reliability, there are increasing demands to replace these kinds of sensors by contactless displacement sensors, with almost no increases in the system costs.
Beside the contactless demand, the sensor should work without friction of moving parts and thus allows big airgaps. To avoid additional developments and risks, the technology should be standardised for all kind of displacements (rotary and linear). A high performance sensor technology for displacement sensing has been developed to fulfil these requirements.
