Wiesemann & Theis GmbH



We develop our own products. This enables us for example to expertly address any problems that may occur in terms of the interoperability that we strive for.


We not only develop our own products, we also manufacture them ourselves so that they are continuously monitored and improved. The results speak for themselves: more than 99.9% quality and reliability in 2009. More...


A large inventory of finished and raw parts ensures that short delivery times are the rule even during the occasional semiconductor shortages.


We document product characteristics as clearly and completely as possible; and we answer your questions without delay.
We also are concerned with extreme long-term availability of our products. In our 25-year history we have never had to phase out a single product.
