RH Electronics is a qualified specialist company and a member of the Chamber of Crafts. It was founded in 1994 by the owner Rainer Hutterer. Initially, video, music, antenna and satellite systems as well as electrical systems were planned and installed. The sale and maintenance of the equipment were also part of the activities of RH Electronics. With some well-known manufacturers even factory representatives for warranty and service were taken over.

In the course of the years an increasing demand developed from the ranges electrical engineering, electronics development, sample construction and small series. It became clear that special productions of mechanical and electronic components had to be created, because until now no manufacturer or supplier was able to meet this requirement in small quantities and flexibly.

By purchasing special machines, RH Electronics was able to respond even better and faster to customer requirements.

Environment / CO2

We repair thousands of ECUs every year in order to reuse them. The nice side effect is that the electronics are not scrapped, but are reused. The repair consumes only a small portion of the energy that would be required to produce a new device. The vehicles remain functional for longer and do not have to be replaced with new vehicles.
We therefore work absolutely sustainably and save CO2.
If possible, we continue to use packaging material in order to protect the environment. Only a small part of the packaging material is renewed.
In addition, we are involved in the dual system, our registration number is DE1954712920821


In recent years, we have developed from a classic craftsman’s business to a service-oriented service company. Numerous, partly very different projects from industry, medical technology, trade and handicraft, automobile industry, manufacturers, small tradesmen, model builders and private persons were worked on by us.

Today, our team focuses on repairing control units. We see ourselves as a supra-regional problem solver in this area, because we offer our customers a service that goes beyond what is customary in the industry:

We have several diagnostic testers with software in our workshop and are therefore able to check and simulate vehicle faults ourselves.

Also a coding on the respective vehicle is possible with us in the house.

After repair in our house we check the device and test it additionally for tightness (compressed air method).

If a spare part is needed, we have it in stock at any time. All spare parts are semiconductors with higher quality than previously used in the devices.

If a repair should not be possible unexpectedly, we have a large number of the usual devices for our customers as new devices and used devices in stock.
