The characteristic feature of our new developed slip ring PME is the modern design and the big variety of applications and variations of the product specifications. Due to the modular extendable segments it can be adopted flexible to the particular requirements. Various materials for rings and brushes allow the transmission of high electrical power, signals and data for different BUS-systems.


The bottom and the top of the housing are made of aluminium. The modular extendable segments are made of thermoplastic material and they are connected by rubber sealing rings. The lamella design of the top of the housing helps eliminating high temperatures inside the housing.


The cable entries of the rings are integrated axial; the entries of the brushes are integrated radial. 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 two radial cable glands at the side of the housing. The cables of the rings are led through the central pipe. The cabling is already carried out completely with a standard length of 2 meters. Customized solutions are possible. Also plug and socket solutions are possible.

Three different module sizes with power ratings of 20A, 50A and 100A are available. Rings and brushes are made of copper-graphite 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.


The slip ring PMP is also the base for several accessory parts like absolute encoders, micro switches or an additional media lead-through.
