PCB Slip Rings

Many customers ask that question before they buy the PCB slip ring. They want to know whether ACB can carry out the normal function of a slip ring. Before you read whether the slip ring is reliable, perhaps it is good to understand what a PCB slip ring is and how manufacturers make it work.

Manufacturers use a slip ring to transfer signals and currents in rotating surfaces. Since the production and operation of machines require communication, slip rings come in handy, as they can transmit current, electricity, signal, or data from one part of the device to another.

What if the space to install a Slip Ring is limited?

At times, you might have limited space for installing a slip ring. With many types of slip rings in the market, customers look for a suitable slip ring to use in such situations. One such slip ring is the PCB slip ring. Read here to know what the slip ring is all about.

What is a PCB Slip Ring?

A PCB slip ring is a form of an ultra-thin ring that manufacturers design to use when vertical space is limited, and the horizontal one less restrictive. Also known as the pancake slip ring, it performs functions just as the regular slip ring only in a specific space limit.

The slip ring is usually skinny, light, and pancake-like. Its conductors are at the flat disc and the centric rings centered on the rotating shaft. When customers are buying, they choose between radial cable output with minimal height and axial cable output.

What is the PCB Slip Ring composition?

What is the PCB slip ring made of? Understanding it can make every customer know if it is reliable or not. Many manufacturers make the PCB slip ring. Each of them tries to make a PCB slip ring that is functional to customers. In every slip ring, there are two parts:

  • The surface: It is the one that gives it the pancake look. It is flat to occupy horizontal space in a situation where space is short to going upwards. Manufacturers use different materials to make the surface, but it is usually of the thick copper layer and coated with Gold coating.
  • Brushes: Just like any other slip ring, brushes are present in it to transmit signals. In the PCB slip ring, the brushes can be of different materials depending on the manufacturer. The brushes can be of varying metal alloys or made using fiber technology that is advanced and more reliable.

The combinations of the surface house the brushes, which brush against the conductive metal and, in the process, transmit signals, data or electricity. That gives the slip ring desirable features of sending data and power in fluid media.

What features make the PCB Slip Ring unique?

Due to the materials that manufacturers use in making the PCB slip ring, the device has unique features that make sit different from the rest. The following are the features that make the slip ring suitable for use by customers:


  • Needs a small space for installing: For customers planning to install a slip ring but have limited space, the pancake slip ring is handy as it occupies little horizontal and vertical space. With a thickness of up to 5.8m, it is best when you are working in a limited space but still want it to function normally.
  • It causes low friction: There is the brushing of the brushes to the conductive metal. Most manufacturers use copper and gold to make the surface and fiber technology to make the brushes. That reduces rusting possibilities hence less friction between the moving and stationary parts.
  • Low electrical noise: If there is no friction, there is no noise when the machine or device is working, making the environment the device is operating in quiet and conducive and favorable to work in.
  • Low torque: The brushes brush against the conductive metal with minimal friction. That reduces the torque making the slip ring powerful to use in complex machines
  • The slip rig requires minimal maintenance: With no resistance, there is no earing of the slip ring. The fiber brushes require no lubrication. The customer does not incur much in terms of maintenance, making it cost-effective to use.
  • The slip ring is durable: The surface is of copper. Also, it has a coating of precious gold metal which makes it durable since it does not wear out. The brushes too are of fiber and do not cause friction when brushing against the conductive when transmitting the signal. That makes the PCB slip ring durable to have and use.

Back to the question, is PCB Slip Ring reliable?

When a customer is looking for reliability in a slip ring, he or she is looking for a probability that the device will perform satisfactorily for a given time under average condition. With that in mind, is the slip ring reliable to use in your machine or machine?

The answer is YES. The PCB slip ring proves to be reliable, effective, and efficient in transmitting signals and electricity from rotary parts to the stationary parts of a machine. The material manufacturers use to make them suitable for the function.

Why is it reliable?

  • Functions efficiently under normal conditions
  • It lasts for long so no need for customers to worry about the constant changing of the slip ring
  • Last long since there is no friction and tearing out when in action
  • Utilize minimal space yet still function just like any other slip ring
  • Produces less noise while working, making it suitable for a working environment.

With all the above points, any customer can conclude that the PCB slip rings are reliable to have. Buying them from a proper manufacturer gives you full functionality that you want for your rotating machines. The slip ring has been tested and proven reliable to us in any industrial setting.

Final Thoughts!

Any customer asking whether the PCB slip ring is reliable; the answer lies on how manufacturers make it. Most have a copper and gold coating surface with fiber brushes that make the slip ring durable, sturdy, and cost less to maintain making the slip ring efficient and reliable to use.
