Products and Solutions

This section provides you with a summarising overview of our current range of products and services. It comprises input systems, components and the area of OEM production. Simply browse through our range of products and get in touch with us should you require a certain item or should you have any questions. We will be glad to help you find any particular articles.

Production is certified complying with DIN ISO 9002 and takes place in clean room conditions. During production, each manufacturing step is subject to sophisticated checks. Exclusively quality products from recognised companies are used, e.g. 3M, Inovan or Autotype. The final products are subjected to a 100% check. We have been familiar with the material since 1983, and this is why you can expect not only outstanding solutions from us, but also an attractive price/performance ratio. You need samples within a few days? No problem for us. The bottom line: we are skilled partners for the professional implementation of your tasks!

Input Systems

With us, the planning and implementation of your input systems is in good hands. After a thorough project analysis run by our product managers and the development department, the conception, design and technical implementations are then specified in a joint, partnership-based dialogue. After all, keyboards are the most important interfaces to the user and thus the 'calling card’ of your product. Here, we guarantee a cohesive concept, from the idea, through planning, all the way to the finished product, and thus the ideal requirement for success in the market. Before series manufacturing, scaled corrections and series-mature samples are created.
