Electromechanical switching systems

When it comes to electromechanical switching, we are a strong systems partner. Our design department will develop the right incremental encoder for your needs. We then engineer a switching mechanism and all mechanical components, including the electronic interface to your control system – all according to your precise requirements.

Sensor-based input systems

Whether, capacitive or optical, we develop and produce sensor-based input systems to fit your application. We distinguish between touch-sensitive keypads, and non-contact optical control elements using the time-of-flight method.
