About Sedlbauer
Founded in 1899 and headquartered in Röhrnbach, SEDLBAUER AG is an established industry partner for electromechanical systems, medical isolation transformers, inductive components, power supplies and special-purpose machinery. The company manufactures simple and complex sheet-metal parts, housings and electromechanical assemblies (EMS) up to complete systems, as well as automated assemblies and special-purpose machines including pneumatic, hydraulic and electromechanical systems. In winding technology, toroidal transformers, transducers and chokes are produced and tested with in-house transformer test systems. Own products include the Polytronik® toroidal transformers, the polyMIT® and polyMIT® e medical isolation transformer series and the polyHEAT® connection unit for infrared heaters. Since 2011, Sedlbauer has also developed charging stations for hybrid and electric vehicles; well over 3,000 charging points across Europe are equipped with this technology. Fields of activity include medical technology, electrical engineering/electronics, audio/hi-fi technology, communications technology, metrology and lighting applications. The company is part of the Edwanz Group (Deutronic GmbH, b-plus GmbH, SEDLBAUER AG).
