The characteristic feature of our slip ring PRM can be seen in the robust housing. It can be adopted flexible to the particular requirements by its different cover heights. Various materials for rings and brushes allow the transmission of high electrical power, signals and data for different BUS-systems.

The base plate of the housing and the cover are made of steel. Overall five different cover heights are available which are chosen regarding to the number of rings demanded.

The cable entries of the rings and brushes are integrated axial. The division of rotator and stator happens in the centre of the base part. In a radius of 75mm the rotating central pipe is located with the above inside the housing mounted rings on it. The brushes are fixed on top of the base part.

The cable exit of the brushes is realized by max. two axial cable glands on the base plate. The cables of the rings are led through the central pipe with an inner diameter of 42mm. The slip ring is already pre-wired with a standard cable length of 2m. Customized versions including plug and socket solutions are available on request.

Three different module sizes with power ratings of 20A, 30A and 50A are available. Rings and brushes are made of coppergraphite and can be covered with a silver or gold coating. This leads to a higher contact performance and influences the abrasion characteristics in a positive way.
