Further remarks

Remark:
This combination of contactless data and power channels offers improved lifetime without the need for maintenance. The contactless design allows very high rotational speeds in comparison to slip ring designs.
The data channels are realized by rotating capacitive couplers and the power channel is based on an inductive technology.
