About ChenYang Technologies
ChenYang Technologies GmbH & Co. KG was founded in 2002 as an engineering office for sensors and measurement technology and has been based in Finsing near Munich since 2007. The company develops and manufactures Hall-effect sensors and ICs, current and voltage sensors, gear-tooth and speed sensors, proximity switches, magnetoresistive speed sensors as well as measuring instruments such as gaussmeters, fluxmeters and magnetic pole detectors. In addition, permanent magnetic products made of NdFeB, SmCo, hard ferrite, Alnico and flexible magnets as well as ferrite cores and soft ferrite materials are offered. Manufacturing is partly in-house in Germany, complemented by cooperation with partner companies in Shanghai and Hong Kong. Development work focuses on electromagnetic measurement technology, measurement of weak magnetic fields and currents, speed and position measurement, and computer-controlled measurement and test systems. Cooperations exist with Shanghai University of Science and Technology and the Technical University of Munich. Products are distributed worldwide from Germany.
