12.5mm 300Rpm 6 Wires CIRCUITSx2A Capsule Electrical Slip Ring for Monitor Robotic Electrical Test Equipment 1Pcs

Worked as described

It works, feels smooth, and there’s continuity across each of the six wires (not between them). Now, you mount the flange to either the stationary or rotating assembly. The other side is *not mounted to anything,* the wires are routed and boom, you can transmit power across an infinitely revolute joint. If you want to use this with a motor, it’s possible but not in the way other reviewers think it is. There are slip rings meant to be used with motors, they’re called Hollow slip rings. I use this slip ring within bearings, and my rotating assembly is driven by a ring gear and a stepper, so I don’t need the hollow type

Excellent product. I withheld one star because I believe that the shaft should be a little longer. I've purchased and used this item 3 times.

Using on a rotating Christmas tree. I used in 3 wire pairs to run 120v -6A Christmas lights. The original wiper went bad and could have caused a fire.

This dandy little product allows you to wire an electrified moving item (small windmill or garden item, turntable, robotic arm, etc.) while the other end of the wiring remains stationary. This allows motion where required without twisting the wiring with each movement. The price is not too high given the nicely designed and small size though better description in the advertising would be welcomed.

I use these on solar trackers that revolve to always point at the sun. These are used on model boats, cars and trains which are solar powered and would otherwise twist the wires. I like to use all six wires for a two wire circuit which effectively increases the gauge. It’s sad to see people giving a low rating because they can’t figure out how to attach the end opposite the flange. You don’t need to attach it to anything. Just let the wires run out and they will not get twisted. Duh.

I use this to supply power and data to the pixels in my Ferris wheel. It's subjected to rain/sleet/snow/ice 3 months out the year and has never let me down.

Slip ring shorted out on first use.
