Yes, they are not actually made for use on aircraft but they are of that style. Even the way-cheap versions are very reliable and easy to use. If driving a motor you really must do the math and compute the voltage drop and keep it to maybe less than 2%. Twisted pairs really do help. I think it

This kind of STP patch cord is really common. Buy it and cut the RJ45 ends off if you need another connector type. But RJ45 is about as good as you need. These cables have twisted pairs with sheild over each pair and then a second sheild over the entire bundle.This cable is suitable for 1

Title says most of it. Looking for 4 pair cable, power/ground on one pair, then A, B, Index pairs. As a quick and dirty I will set it up with Cat 5 cable to start then switch to something made for flexing. DigiKey shows 3 pair and 6 pair but not 4 in a flex cable. Ed. __
