Need help with rotating electrical connection!
Hey guys,
I'm doing a project and would appreciate some help. I essentially have a DC motor controlling a blade from the center. On the blade is a sensor that I need to wire to the main circuit that is below the DC motor. The problem is when the blade rotates the wires will obviously tangle.
I know slip rings may work but I hear they are generally expensive and very noisy. I have read on some things like using audio jacks with maybe some coaxial cable. The sensor has 4 connecting wires, and whatever the rotating mechanism is, won't be able to be placed at the center because that's where the motor is, or am I wrong?
I'd really appreciate if anyone could help me. Thanks :)

Phone untangler thingy
There is a swivel connector that you connect to your phone handset to stop the cable from winding up. They are cheap, and and have four connections I believe. Should work well for low rpm applications.

Ball bearings
You could try ball bearings like this guy:

I haven't tried it myself but it looks promising.

what speed is the blade
what speed is the blade doing? (Revolutions per min)

How would I go about this?Do
How would I go about this?
Do I connect the 4 wires to where the male part would be and then run that down to the main circuit where a fixed female jack would be? I'm just trying to visualize this.
Also do you know how many wires are inside a coaxial audio cable? If theres less than 4 would it be possible to use 2 of these cables?
Thanks for the help!
