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.

New slip ring platform for "high-end" transmission

Due to the increasing networking of all components of a plant / machine and the associated complexity of machine controllers, through to the implementation of Industry 4.0 concepts such as Condition Monitoring, the demand for high-end data transmission is growing. Following this trend, Kübler has developed a new, future-proof slip ring platform, which on the one hand is equipped with reliable "high-end" transmission technology in a maximally compact design and on the other hand has a 1 Gbit module. This operates without further electronic components and thus enables interference-free, reliable and direct transmission.


"Strong transmission"
Load transmission requirements of up to 800 V and 80 A per transmission path are covered with the new slip ring platform.

The new modular slip ring platform is designed for slip rings with a freely usable hollow shaft of up to 50 mm and forms the basis for our sizes from 130 mm. In addition to a version with a hollow shaft, we also offer a flange version as standard. Furthermore, any form of customer-specific adaptation is possible with the new slip ring platform, both mechanically and electrically.

The 1 Gbit module

For integrated Industry 4.0 concepts.
The new slip ring platform is equipped with a so-called 1 Gbit module. This operates without any additional electronic components and thus enables interference-free, reliable and direct transmission. The Ethernet module is a bus-independent and cost-optimized solution.
Smart Slip ring - IIoT enabler
Slip rings for Industrial Ethernet transmissionalso ensure that Industry 4.0 / IIoT concepts can be implemented in every angle of the machine.
