ODU – a success story made in Mühldorf am Inn

Competent and innovative for over 80 years: Otto Dunkel founded his company to manufacture connectors and contacts back in 1942. As a pioneer in the industry, ODU quickly made a name for itself. Its technologies for transmission and measurement of power, signals, data, and media have enjoyed a first-class reputation ever since the company was founded.

This is the legacy on which ODU continues to build to this day. It is also the foundation for a success story that has transformed the company, headquartered in the tranquil town of Mühldorf am Inn in Upper Bavaria, into a global market leader in the development and production of mass interconnect systems.
