Sliding contacts (brushes) for custom slip ring


I am looking for a supplier of metallic sliding contacts/ brusches for an in-house development of a slip ring to transfer data and power from a rotating spindle to the stationary housing. For space reasons, I have to integrate the slip ring into my other structure and cannot use a standard part.
I have already built and successfully tested a demonstrator with the de-soldered sliding contacts of a standard slip ring. However, for a planned small series I would like to do without always buying very expensive slip rings and soldering out their sliding contacts (which are probably penny articles). It is also noticeable that the sliding contacts from different slip ring manufacturers look identical and are therefore probably not in-house developments but bought-in parts.

After hours of searching the net, I have not found any suppliers for these contacts. Maybe I’m using the wrong search term.

Does anyone have any tips on where I can find them? For clarification, here are two links to a product page of standart slip rings utilizing such contacts, which are usually soldered onto a PCB on one of the two sides: PCB slip ring | flat slip ring | flat disc electrical slip ring - MOFLON or Pancake Slip Rings | Slip Ring Pancake | Pancake Slipring - MOFLON

I’m thankful for any hint.

Unfortunately we do not carry these type of parts.

Hey @JustSomeRandomDIYGuy I’m looking for the same exact thing, did you ever end up finding a supplier?


Hi @starstorms and @JustSomeRandomDIYGuy I too am looking for these exact parts and coming up empty in my search. Did you have any luck? Much appreciated in advance.

Wecome to the technical forum. I did a double check as we do not sell these. Though the link the previous customer provided , that has a live chat option on that website. They should be able to tell you how you can purchase this type of product.

Unfortunately, I had to put the topic on hold for a few months due to other commitments. But I picked it up again a few weeks ago. I had no luck with the companies here in Germany, but MOFLON quickly agreed to supply me with 50 units. The brushes are currently being delivered. As soon as they arrive, I’ll be happy to give you a further assessment.

I appreciate the help. I am based in the US and wasn’t able to find anyone either. I’d love to know your thoughts on the contacts when they arrive. Thank you and nice find!

Final status after a longer break. The brushed arrived just about one week after shipment. They look good and I will include them in my design now.

Here a foto of the delivery:
