Connecting Cable Specification Requirements
To reduce the error caused by the connecting cables, 16AWG to 28AWG conducting wires with 5mm to
6mm stripping length are required. You are recommended to use 20AWG conducting wire with 5.5mm
stripping length. The diameter, area and copper impedance of each kind of conducting wire are as shown
in the table below.
Note: The "Copper Impedance" in the table below refers to the DC impedance of the single-direction
copper wire under 25℃. The temperature coefficient of the copper wire is 0.35%/℃. When a pair of
copper wires is used, the impedance value doubles.
