Welcome to DIAB - We solve your power plug requirements!

 2007 - 25 years in business                                                  

We have devoted a lot of energy over 25 years into improving equipment for the transmission of electrical current between traction vehicles and trailers for mobile transportation. Functionality and safety are imperative requirements for power plugs that must guarantee the transmission of electricity in the toughest of environments.

The requirements-specification that forms the design-basis can be summarised by that we minimise disturbance in the current flow that always arises in a power plug. This is achieved through:

  • Correct choice of materials
  • Sufficient pressure
  • Clean surfaces
  • Total imperviousness


Combined with...

  • User friendliness
  • Staying power and durability


We would like to already claim that our products are the best on the market for achieving this important task. But of course, they could always be better!

We therefore constantly develop and adapt to the sector's requirements.

Our goal has always been - and remains - to provide a product with:

  • High operational safety
  • Long lifecycle
  • Simple handling
  • Good availability of spare parts

Our products can be used for all kinds of vehicle combinations where electrical transmission is required, particularly within the transport sector, as well as for agricultural machines, forestry machines, caravans, road machines, and vehicles that require video monitoring.
