About Bader GmbH
Bader GmbH develops, produces and distributes electronic components and assemblies for industrial automation and automotive applications. Founded in 1974, the family-owned company based in Freiberg am Neckar has been in the market since 1990 with microprocessor-controlled CAN bus systems and specializes in climate control for buses, rail vehicles and special-purpose vehicles. The product range includes operator devices such as the KR-323, KR-490, KR-494, KR-498 and KR-590 climate controllers, as well as programmable CAN nodes and stand-alone control units. In addition, the company develops customer-specific electronic systems including hardware and embedded software development. The complete manufacturing process – from procurement through assembly, soldering and testing to final assembly – takes place at the Freiberg am Neckar site. SMD and THT assembly, vapor phase and wave soldering enable small, medium and high production volumes. Customers are manufacturers of commercial vehicles and their suppliers.
