SEDLBAUER develops and produces high-quality inductive components based on toroidal coils and for over more than 70 years Polytronik® Toroidal Transformers. We offer a wide standard range as well as custom solutions.
Polytronik® toroidal transformers are best suited to use in modern, powerful equipment and system components in the entire field of electrics and electronics (for example audio/hi-fi equipment, medical engineering, telecommunications, metrology, halogen lighting and alternative energy sources such as photovoltaics).
They particularly stand out for their high performance in compact sizes, extremely low magnetic leakage, maximum efficiency and excellent temperature characteristics. Compared to „normal“ transformers Polytronik® Toroidal Transformers are reduced in weight (up to 50%) and have a maximum efficiency of up to 98%!
Furthermore, we offer an large range of medical isolation transformers and pulse transformers.

We offer custom, cost-effective solutions to help you fulfil your project. With our wealth of technology expertise, we can provide expert technical support and guidance at every stage of your design.
Working closely with world-leading suppliers, we act as your design partner, working with you on your design challenges and helping you make informed product decisions that are most suitable for your application.
Our team of technical experts will be able to guide you through the design process, product options and selection, technology integration and manufacturing, including prototyping and production samples.
If you just need products for your production requirements, we can also support your bill of material needs.

The main focus of our products is structured in the fields of Acoustics, Inductivities, Cable-Connector, Accumulators
Work out your requirement profile with us.
We offer you, supplementary to standard, special solutions oriented on your application. As your contact partner for development as well as toolmaking we attend you during the entire project phase. In close arrangement with our Product Manager in Asia, the implementation will be co-ordinated and carried out.
