The charging/discharging of a battery (1u to 30 mA) and remote voltage measurement is to be performed over 2 pairs of 2 m cable. In order to reduce picked up common mode noise I intend to use shielded twisted pair cable.
But I don't know which one to choose. There are several properties to consider.
The first is the gauge. This one is clear: the thicker, the better.
Somewhat more obscure are the types that listed i. e on Mouser: what is the real difference beetween those types?
Then there is insulation and jacket material. I am not sure whether I need to consider it in the first place?
And the last and most difficult is the shield itself.
I know that there are braided shield, which has lower resistance, and foil which has better coverage. But I can't decide what of that is more important (?)
Is there perhaps something else that has to be taken in account?
I would like to get anwsers disregarding whether you think I need shielding or not.
EDIT: this what I see if I attach oscilloscope probe to a 1.8 m unconnected unshielded cable:
