Cabel length is halved since the supply and GND line form the entire length.
LCable = Lwire / 2
Legend:
U = Voltage drop ( 5 V supply – minimum encode supply)
R = Wire resistance
I = Maximum required encoder current
ρ (rho) = Specific resistance of the wire (0.017 Ω for copper)
Lwire = Entire wire length (supply line + ground line)
Lcable = Entire cable length (Lwire / 2)
A = Encoder cable cross section
