Who we are

Wiesemann & Theis GmbH, W&T for short, is a family-owned company which has seen continuous growth since its founding in 1979, with headquarters on the perimeter of the city of Wuppertal.

What we do

Here in Wuppertal we produce durable small computers for DIN rail mounting. These connect sensors and actuators directly to a network, so that they can be accessed from anywhere. Industry 4.0 is not just a slogan for us, it is practical reality.

How we do it

We consciously ensure that the entire process chain takes place completely on-site:
• Development
• Circuit board production
• Assembly of the devices
• Testing
• Technical support
• Sales
• Shipping
Because of our short paths we are able to respond quickly and flexibly to customer desires, which our customers appreciate as well as our ability to get to the heart of the problems that networks so often present.

Who our customers are

Our customers can be found especially in the industrial field, in companies of every size and around the world.
