Slip Rings


Individual solutions are our strength!


Slip rings (rotary transmitters, rotary splitters) are used to transmit electrical power and signals (analog, BUS, video, Ethernet, etc.) from a stationary to an endlessly rotating component. They are used in applications such as packaging machines, filling lines, revolving doors, medical equipment, rotary tables, cable drums and all types of production machines. 


A slip ring consists of a slip ring body and a current collector (brush block) and is used in most applications as an encapsulated version with housing and own bearing. We have a very wide range with countless solutions for flange and hollow shaft applications as well as for open modular rotary distributors and flat disc slip rings.


Our slip rings are maintenance free and can also be combined with rotary unions for pneumatic, hydraulic, water, vacuum, gas or other media. In addition to standards, we also develop application-specific slip rings that mechanically and electrically meet customer requirements.

TDS Precision Products GmbH implements solutions in the fields of rotary transmitters, drive technology, sensor technology and positioning technology.
