The position sensors for magnetic bearings are very important parts of such a system. It is possible to say they are one of the most exacting part there because lot of conflicting demands are posed on them. This presentation describes the sensors for textile spinning machines which must have not only usual technical features but, in addition, they should fulfill the specific requirements of this industry, especially functionality in very dusty environment, resistance against foreign magnetic fields and last not least also potential for economical mass production without individual hardware setting and without selecting of specific components. Simply told, the prices at this market segment are forced down but the quality and reliability must be kept high.
