With a slip ring assembly, your electronics can now twist and turn safely. Add wheel encoders, 360 degree sensors, rotating LEDs, rotors and more! We've seen a lot of people DIY slip ring's out of desperation but no longer, simply pick up one of these to solve any rotation needs you have.
This is a toroidal slip ring - a more expensive type of slip ring. Unlike the other capsule-type 'rings, this one has a through-bore hole in the center with a (just slightly larger than) 1/2" diameter. There are two set screws in the aluminum collar of the 'ring, so you can firmly attach it to a rotating shaft. Since these are used more often for industrial equipment, they're more expensive, but they're by far the best way to solve the problem of passing data/power to something that rotates.
Inside the casing is a gold plated slip ring for 6 wires. There are six color coded wire sets made of 22 AWG and no matter how you twist the assembly, they will remain in continuity. Each of the wire sets can carry up to 5A at up to 380VAC or 240VDC. Rated to rotate up to 500 RPM (but you can probably go faster if you don't mind a reduced life and/or noise).
The Toroid Slip Ring - 2.1 OD 1/2 ID, 6 wires, max 240V @ 5A appears in the following collections:
