Description: This is a 6 wire slip ring, a remarkably simple electromechanical assembly that allows electronic signals to be passed through its rotating innards. Commonly, you’d find slip rings in wind turbines, radar antennae, or anything else that requires continuous 360° rotation while maintaining an electrical connection. This particular slip ring provides you with a compact body with gold-on-gold alloy fiber brush to plated ring contacts inside.

Each Slip ring is capable of handling a continuous working speed of 250RPM, a current rating of 2A, and an operating voltage of 210VDC / 240VAC. We aren’t kidding about how compact this little guy is, with only and outer diameter of 22mm for the body an 44.5mm diameter flange, you should have no issues fitting these into your next project. Additionally, the 250mm stranded wires protruding from each side of the slip ring have a thickness of 28AWG while the whole assembly has a water protection rating of IP51.

Dimensions: 22mm Diameter x 19.5mm Length w/ 44.5mm Diameter Flange

  • 6 wires
  • Voltage: 210VDC / 240VAC

Customer Comments

  • Is it feasible to use this slip ring to measure degrees of rotation disc?

  • Is there anyway to get these with a 4 bolt pattern to match the 0.770" hub pattern from Actobotics?

  • Please get more of these in stock and please get the flange less version too. I bought one from a competitor and it took a week to get here. It also was $13 shipping UPS ground. Which is ridiculous. I came here first before buying but nothing was in stock. I was going to get this version and chop off the flange.

Works well, but mind the specs.

I’ve created a 1m RGB POV display based on LPD8806 LED strips, and this slip ring. It worked great for development, and probably lasted a month of evening dev time, or 100-200 hours. No problem handing high data rates. But I was running it out of spec at 300-420 rpm. I knew I was taking a chance but wanted to push it to the limits. I installed it in it’s home for 3 months, and the slip ring failed soon after. When it fails with the LPD8806 you’ll see a Stanley Kubrick-esque radial display of chaos. It actually looks really cool to those who don’t understand, but it indicates that the clock and data lines have an intermittent connection as the slip ring turns.

Long story short, I recommend this for within spec projects that stay under 250 RPM and do not have huge duty cycle requirements. Beyond that you should look at industrial-strength replacements like those from mercotac or similar. Look closely at the max RPM specs, and duty cycle if available. A duty cycle or lifetime spec for this product would be helpful. 250 RPM might be useful if your POV has 3-4 arms and therefore needs less RPM than a dual-arm.


Excellent device

Works perfectly and solves the very difficult problem of getting power and signals to a rotating platform
