Our Mission

Sensor intelligence, independenceinnovation, and leadership are the core messages of our identity. Identity manifests itself at the interface between the past and the future. Our statement also has its place between yesterday and tomorrow. It carries strengths, wishes, demands and visions within it. It builds on a mature corporate culture and is a draft for the future that is both a commitment and a motivation.

Only those who think independently can also act independently. This is equally true of the people and the company. Only an independent head has the freedom to do something in the way he believes is right. Freedom, however, also means acting within limits, with an aim and clear rules.

Innovations are noticeable improvements that bring benefits. By innovation, we understand not merely the invention and development of new products, production methods and organisational structures, but also their implementation. The commercial success of new products is thus indispensable, if only because innovations must also be financed.
Leadership is shown by one becoming an orientation point for others. This applies for management personalities who can imbue teams with enthusiasm, as well as for companies that set standards on the world market. For us, leadership not only means technology and market leadership but also a leadership culture and optimum mastery of methods and processes.
