Adafruit Miniature Slip Ring - 12mm diameter, 12 wires, max 240V @ 2A

With a slip ring assembly, your electronics can now twist and turn safely. Add wheel encoders, 360-degree sensors, rotating LEDs, rotors, and more! Many have attempted DIY slip rings out of necessity, but now, simply use this solution for all your rotation needs.

Inside the miniature plastic tube is a gold-plated slip ring for 12 wires. These are color-coded and made of 28 AWG, maintaining continuity regardless of twists. Each wire set can carry up to 2A at up to 240VAC or 240VDC, making it highly versatile.

This model is the tiniest slip ring available, measuring just 20mm long and 12mm in diameter. It's rated for up to 300 RPM, though higher speeds are possible with potential trade-offs in lifespan and noise level.
