The McNaughton-McKay Group (MMG) is one of the most powerful distribution companies in the North American market. Since 1910, the group has been synonymous with innovative electrical engineering products and sustainable solutions and services that support the profitable business development of its customers.
With 1,900 employees, headquarters in Madison Heights (Michigan) and over 62 branches in 9 US states, MMG is one of the leading distributors of automation technology and one of Rockwell Automation‘s longest-standing partners worldwide. The company has been wholly owned by its employees since 2006.
MMG goes beyond pure product distribution and focuses on long-term partnerships. This is based on a large and diverse inventory, local expertise and practical, scalable solutions for the efficient implementation of even complex projects.

MMG offers a comprehensive product portfolio from more than 450 manufacturers. This means that we, as S&D, are also able to provide you with fast and, above all, easy access to industrial automation and network technology, drive and servo technology, process solutions and many other product areas from the North American market.

In parallel with the Rockwell Automation portfolio, MMG distributes the entire product range from Panduit, nVent Hoffman, Osram Sylvania, Thomas & Betts, Mersen, Appleton, Lithonia, SolaHD and many other partners.
We have been a subsidiary of MMG since 2007 and are currently the only branch outside the USA. As the link between North American manufacturers and European customers, we at S&D are responsible for the European market.
Thanks to our close ties to our parent company in the USA, we have direct access to comprehensive services and enjoy the highest priority. You communicate in your local language and during your business hours – we take care of coordination in North America.
This saves time, reduces costs and enables efficient delivery routes between Madison Heights and our warehouse in Krefeld.
For short-term supply, our parent company maintains several logistics centres with inventory worth over €160 million. Even subsequent deliveries to end customers in the USA are handled entirely by our organisation.
