On the road to success since 1967

LINK has been producing sophisticated components for security technology and building automation for over 50 years. LINK sensors are installed in the Berlin Reichstag, the newly rebuilt Berlin Palace and the European Central Bank in Frankfurt, as well as in numerous embassies, banks, museums and industrial buildings. The three pillars of our success are our customer focus, innovation and extremely high quality standards. These principles have helped us earn the trust of our business partners.

Our history began in 1967 near Frankfurt am Main with the production of individually tailored magnetic contacts. Today we are one of the largest manufacturers of magnetic contacts in Europe and are certified according to VdS, EN and many other country-specific standards. Daniel and Markus Link took the business over from their father and expanded it into a medium-sized high-tech company. All manufacturing-related processes – consulting, development, design and production – are now united under one roof. The one-time family business has grown into an owner-managed medium-sized company with around 140 employees and a strong focus on the future. We develop and produce security products for international technology companies. Our flexibility and attention to detail allow us to quickly and effectively implement individually tailored solutions – all “Made in Germany”.
