All details about our slip rings clearly arranged in the catalogue

USB Slip Rings

USB slip rings for unlimited possibilities. Even if many people only know the USB port from chargers and data sticks, this PC standard can do much more. It is no coincidence that USB means nothing less than “Universal Serial Bus System”. This means that today there is practically no end device that cannot be supplied with power or data via a USB port. In addition, USB ports also offer the possibility of an interface for wireless data transmission. Bluetooth, infrared, radio or light line – with a USB port, the whole world is open to you. With the USB slip ring, you can now also accommodate this international standard on rotating modules.

Hybrid transmission of data and power

USB Slip Rings

USB transmission according to standards USB1.0, USB2.0 and USB3.0, USB3.1, USB3.2 with up to 20GBit/s.

Design capsulated or with hollow shaft

We manufacture the USB slip rings in an encapsulated housing or on request also with a hollow shaft. The hollow shafts can have different diameters.

Different housing materials to choose from

The housing material of the USB slip rings is selected after consultation with our customers. From plastic to stainless steel, many possibilities, including combinations, are available. Please feel free to consult us about the different possibilities in this area.

USB socket directly in the housing

As connection options, we can either provide cables with USB sockets or USB plugs in different lengths, or mount the sockets (as shown in the picture) directly in the housing.

Torque support for fixing the stator

To fix the stator side of the USB slip rings, we provide a torque support as standard, which can be screwed to the housing. Alternatively, we can make another modification to the housing to provide the customer with a different type of positive connection. Please feel free to contact us for advice on the various options in this area.

Functionality of USB slip rings

Ultimately, a USB contact is also nothing more than a completely normal current feed-through. Regardless of whether data or (to a limited extent) power current is to be passed on, nothing changes in the proven slip ring-brush technology in the USB slip ring. The familiar USB ports are attached to the rotor and stator of the slip ring housing. It is true that there are only very few applications that really require permanent rotation from a USB end device. However, there are all the more applications where a swivelling USB feed-through can simplify certain situations considerably. Until now, this was only possible with cables, where there was always the risk of twisting. This creeping winding of the cable always ends in breakage or tearing. With the USB slip ring, however, the connection always remains relaxed and fully available at any angle of rotation.

Advantages of the USB slip rings from rotarX

Our USB slip rings can offer you the following advantages:

  • Thoughtful, innovative design
  • Robust housing made of sturdy aluminium
  • High load capacity
  • Rotates up to 600 revolutions per minute
  • Finished with gold-gold contacts
  • Available in many variants
  • Standardly in protection class IP51, higher on request

The compact and high-strength housing is made of aluminium. The integrated drive lug is also made of this proven metal. This makes the USB slip ring corrosion-resistant. The rotary movement of the application is transferred to the slip ring by means of the drive plate.

The USB slip ring can be rotated on both sides. With a large selection, the right USB slip ring is also available for your application. The protection class IP51 makes the slip ring insensitive to penetrating dust and splash water. If you need more protection, please contact us. We will also find the right USB slip ring for your applications.

Selection of USB slip rings

We can offer you USB slip rings with one to 36 passages. Each USB slip ring complies with the USB 2.0 class. However, they are also downward compatible. If you have applications that need to use USB 3.0, please contact us. In this case, too, we will find a suitable solution for you.

Our USB slip rings can transmit both signals and power feedthroughs up to 20 amps. The maximum working voltage is a full 440 volts for both direct and alternating current. Voltage peaks can be intercepted up to 500 volts at 50 hertz. The electrical noise is a maximum of 10 milliohms. With an insulation resistance of 1000 megohms at 500 volts DC, each of our USB slip rings is also well equipped for unexpectedly high loads.

With up to 600 revolutions per minute, the USB slip ring leaves nothing to be desired in terms of dynamic load. A maximum of two USB feedthroughs can be integrated. Each USB slip ring can be loaded from -30 °C to + 80 °C. If your requirements lie outside this temperature range, please let us know. We will find the ideal solution for this as well.

Installation of the USB slip rings

The installation of the USB slip rings is as easy as with any other of our slip rings. Once you have installed it in its place of use, you only need to connect the incoming and outgoing cables. The cables are marked identically on both sides so that confusion is impossible. With an exactly centric positioning, you permanently avoid the possibility of a drill.

Use of USB slip rings

The great strength of the USB slip ring is that it can rotatably connect devices with a USB connection. The great advantage of USB connections is their widespread use. All you need is any end device, for example a sensor or a camera, and a USB cable. With the USB slip ring, you have full freedom of movement in the application you want. In addition to the permanent installation of a USB application, USB slip rings are also perfect for maintenance and inspection of end devices.

If, for example, you have a fast rotating sensor with its own control unit in use, you can check it or supply it with new software directly at the pivot point via USB diagnostic device. The USB port makes these slip rings extremely convenient and versatile in their applicability.

Maintenance of the USB slip rings

The USB slip rings require no maintenance apart from occasional external cleaning. They also cannot be dismantled due to their complex and very sensitive inner workings.
