: Hey y'all . . .
: This is my first post to this forum, but I've got a question that I haven't really been able to find an answer for.

: Has anyone suffered any problems with their PWM cables with respect to signal loss? We've (We being team #271) got to run a PWM cable to a servo at the end of a long arm, and we'll need some ridiculous amount of cable. . .something like 12'. Being that the wire is so small in diameter, I was worried about internal resistance and all, and wondering if the signal would get that far.

: Any advice?

Michael,

The servo is an extremely low current signal. Signal loss should not be a problem. I would suggest trying it first before committing to a design.

An alternative is to cut a PWM cable in half and splice a larger AWG for the majority of the run.

Mike
