Ethernet Slip Rings
Ethernet slip rings for reliable transmission of power and signal current in demanding applications. Ethernet is the industry standard for automation technology.
Wherever a production line needs to be largely automated and run at the fastest possible cycle rate, Ethernet is the gold standard. No other data transmission system is better suited to Industry 4.0 production processes. With our Ethernet slip rings, we now also offer you the right rotary feedthroughs for this purpose.
These slip rings not only offer you simple signal transmission over a rotating distance. They can perform this demanding task at phenomenal speeds: our Ethernet slip rings achieve rotational speeds of up to 600 revolutions per minute. At this speed, your processes will leave nothing to be desired.

Functionality of Ethernet Slip Rings
By selecting high-quality materials and employing excellent engineering, we achieve outstanding performance with traditional full-contact technology.
The Ethernet signal is transported to the slip ring via a suitable cable. There, the current pulse is transferred from the brush to the ring and from there to another identically constructed and marked cable. Thanks to corrosion- and abrasion-resistant gold-gold or silver-silver contacts, the signal remains fully accessible and reliable in its transmission even at maximum rotation. With up to 1000 Mbit/second and 600 revolutions per minute, you have all the power reserves you need for your applications.

Advantages of the Ethernet slip rings from rotarX
Our Ethernet slip rings offer you the following advantages:
- Stable mounting
- Robust, shielded housing
- Long service life
- High rotational speed
- High data transfer rate
- Protection class IP 51, higher on request
The high-strength aluminium housing of the Ethernet slip ring is attached to any surface using a screw bracket. Rotating connections such as shafts, pins or axles are ideal. The stator-rotor combination offers you unlimited freedom of rotation in both directions.
This also includes twisting within a limited arc. The housing is interference-suppressed and protected against escaping or intruding signals. The rotational speed and data rate leave nothing to be desired. Thanks to the selection of tested, robust materials, the Ethernet slip rings are very durable.
Selection of the Ethernet Slip Rings
We offer Ethernet slip rings with up to 48 transmission points. Rings for power transmission can also be added. Each power ring can handle a rated current of up to 20 amps. Each ring has a working voltage of 440 volts, regardless of whether it is direct current or alternating current. As a reserve, you have a voltage resistance of up to 500 volts per ring at a mains frequency of 50 hertz. The electrical noise is a maximum of 10 milliohms.
The Ethernet slip ring bodies are tested for insulation resistance of up to 1000 megaohms at 500 volts DC. The Ethernet feedthroughs have one or two channels that can transmit up to 1000 megabits per second. With a rotational speed of up to 600 revolutions per minute, each of our Ethernet slip rings is in a class of its own.
We can offer you slip rings in any cable length. Our Ethernet slip rings operate with consistent reliability from -30 °C to +80 °C.
Installing the Ethernet Slip Rings
Installing our Ethernet slip rings is child’s play. Secure the Ethernet slip ring to the installation site using the screw tab and connect the cables to the system. Each cable has two identical ends, so there is no risk of confusion.
At high rotational speeds, please ensure that the slip ring is positioned exactly centrally to ensure a long service life.
Use of Ethernet slip rings
There are many applications in which Ethernet signals must be transmitted to a rapidly rotating actuator. Virtually all machining centres with sophisticated sensor technology are typical examples of this. Ethernet slip rings in spindles or tool holders can register imbalances or friction losses with the appropriate sensors. This allows the machine control system to slow down or interrupt production at an early stage before serious damage to the machine occurs.
Other applications for Ethernet slip rings can be found in avionics and automotive engineering. Installed in rotor shafts or drive shafts, Ethernet slip rings can forward incoming signals from outside to the control unit. Temperature fluctuations, humidity or other disruptive factors are thus detected within milliseconds and the control unit can react accordingly. This makes these applications particularly reliable and safe.
Ethernet Slip Ring Maintenance
Our Ethernet slip rings are designed for maximum loads. The design of the slip ring bodies means they are maintenance-free for their entire service life. Therefore, no maintenance work is required beyond external cleaning. We offer you highly reliable and durable Ethernet slip rings.
Depending on the design of your application, you have the best possible basis for calculating the interval at which your slip rings may need to be replaced.
