Up-to-date: New design – trusted quality

A new Brand look for MDT

Modern, fresh but still recognisable We have reworked our corporate design. The clear colours and shapes stand for future orientation and a spirit of innovation – just as we do as a manufacturer of innovative KNX products. Our new slogan goes to the core of MDT and reflects our employees’ passion for KNX: “MDT – your KNXpert”.


We have slightly updated the logo, but the characteristic stripes will remain in a reduced form. You can watch us as we develop the logo and slogan here:

MDT company history

New branding

In recent years, MDT has noticeably grown as a manufacturer of innovative KNX products. In order to strengthen our brand and support the internationalisation of the company, we have modernised our logo and the entire branding. The fresh design and the modern logo are seamlessly tied to their predecessors and therefore guarantee that our brand will be recognised.


Extension to the main building

In order to meet the growing demand for KNX products, we expanded our company headquarters in our native Engelskirchen with an extension, which we put into operation in 2019. The new building has increased production and administration capacity by 50%.


First MDT KNX product range

Since 2009, we have exclusively manufactured KNX products. The first range featured XY products. These included binary inputs with integrated logic function – a combination that had not previously existed in any product. Today, we continue to bring new, innovative products to the market.


New company name

The brand name of our working memory was increasingly equated with the company name, which is why we decided to officially change the company’s name from MCI to MDT technologies in 2005.


Flexible working memory production

Computer production was discontinued at the end of 1996. From then onwards, we exclusively produced working memory for PCs. During this phase, our extremely flexible production processes were established because the company aimed for an order placed in the morning to be delivered the same evening.



Today, MDT is known as a manufacturer of leading KNX products. However, MDT had already been operating in the electrical and electronics market for more than 25 years before it started producing KNX components. Since our foundation in 1983, we had produced personal computers and working memory trading under the name MCI.



MDT as a driving force of innovation

We always have our finger on the pulse of the market

The founding idea behind the MDT KNX range emerged on a private building site: “A KNX actuator like this must be able to do more!”. This was followed by laborious development, after which our own first KNX range was launched onto the market. To this day, the core idea of offering the user more functionality runs throughout the entire product range at MDT.


We have put together a selection of products, which when launched contained new functions that had never before been available on the KNX market.
