Our products in detail

FST Encoder Antriebsstrang Driveline


In driveline applications, the Multipole Encoder provides precise measurement of the rotational speed of all wheels using the width of equal poles.
FST Eoncoder Getriebe Transmission


Used in transmissions, the Multipole Encoder provides precise measurement of rotational speed using the length of equal poles. This technology also synchronizes transmission component, allowing for smooth and efficient gear changing.
