Reliable power, signal, and data transmission according to your requirements.

Innovative solutions for the transmission of power, signals, and data are derived from your requirements. With 20 years of experience in the field of transmission technology, Kübler has specialized in certain technologies, having grouped these into technological modular systems for you. From contacting transmission with gold wire or metal graphite brushes, to contactless capacitive, inductive, or optical transmission, to integrated sensors or media lead-throughs for liquids and gases. The design of each slip ring is specially adapted to your wishes. Your advantage: You will receive an individual and tailored slip ring solution for your application.


Contacting slip rings

Contacting transmission is based on special contact brushes that slide against the matching counter-rotating contact rings. The appropriate contact technology is selected based on the application. Our modular system includes a wide range of contacting transmission technologies, including gold wire, silver bundles, and metal graphite brushes.

Contactless slip rings

Contactless transmission is either inductive, capacitive, or optical. Depending on requirements, we also use these technologies in combination with other contactless and contacting transmissions. For example analog signals could be inductive, field buses and Industrial Ethernet up to 16 Gbps capacitive, and power up to 120 A contacting.

Mechanical possibilities

Media lead-through

In addition to electrical transmission, other media are often also connected. We develop the suitable solution for you for a fast and uncomplicated mounting. In short: Plug and Play.

Media lead-through for:
  • Compressed air, vacuum
  • Hydraulics
  • Lubricants
  • Detergents
  • Other fluids

Slip ring design

Whether standard or customized – we offer you the right design for your application. The housing is available in plastic, aluminum, or stainless steel and is therefore protected against water spray, water jets, and dust. In addition, slip rings from Kübler are tested for electromagnetic compatibility (EMC). Integrated sensors such as Kübler encoders, temperature monitoring, and much more are used to implement condition monitoring. And don't forget the connection technology, which we design according to your requirements.
