It will be used for the same purpose as pictured, as an IR emitter though instead of to a stereo jack it will be to PCB pads. No more than ~5v, multistrand, 2 conductors. I believe the cable is usually used for this (ir) or after DC transformers, the stripe indicating the + / signal - colours aren't a must have but nice to have for consistency. I've used it before just not bought it so not sure of what to search for...
