19 World-Class
Manufacturers
Sommer GmbH was acquired by the Interconnect Solutions Group in 1998, establishing ISG's first major European foothold outside the UK. Over more than 25 years, Sommer has grown substantially through a series of strategic acquisitions and integrations that have strengthened both its product range and its geographic reach.
Sommer's growth story mirrors that of ISG itself — built through careful acquisition and integration of complementary businesses. The integration of Rayquick in 2012 expanded the product range; HSP in 2020 added further technical depth; and CTS in 2023 extended Sommer's reach into new German market segments.
Operating from Germany at the heart of Europe's industrial and aerospace supply chain, Sommer GmbH is one of the most significant specialist interconnect distributors in the German-speaking market. The business serves customers across Germany, Austria and Switzerland with a comprehensive product range backed by deep technical expertise.
Sommer GmbH acts as ISG's primary European distribution hub, working closely with Rayfast UK, Filcon Electronic and the group's other European businesses to provide customers with access to the full ISG product portfolio and technical support network.
