About us

Power – wherever it’s needed.

The manufacture of Plug connections und FOC components is our core competence, as attested by over 30 years of global success, with high-performance, quality products in a huge range of models.  

From development and design, in-house toolmaking right through to series production and packaging logistics – all at our one-stop shop: that’s our trademark and quality promise. And this approach has proven itself through short development cycles, fast times to production and delivery, and smooth overall processes. 

As a second and third generation family business, we look back on a number of company traditions. But we’re also geared to the long-term future. We value loyalty, honesty and personability. Our customers benefit from short pathways, which enable quick decisions and responses. We reliably undertake series production, but are equally flexible when it comes to small runs or individual requirements.

Everything we do is geared towards quality components that reliably deliver power wherever it’s needed. We make our customers’ products and processes work and we keep them working. 100% of what we do is Made in Germany.
