Just a quick post to document the differences between 30-Core and 60-Core servo cables.
I was looking for servo extension cables (female to male), but the wire specification confused me. There are “30-Core” and “60-Core”, but explanation of the differences were no where to be found.
So I asked the seller, and I was told the main difference is basically just in the wire diameter.
Differences between 30-Core and 60-Core Servo Cables
30-Core uses 26AWG wires, where 60-Core uses 22AWG wires. (Despite 22AWG is a smaller number, but it’s actually a wider wire than 26AWG – see this post for more detail)
Should I Get 30 Core or 60 Core?
30-Core servo leads are thinner and more suitable for lower current applications such as signals and low power servos. Due to the smaller thickness, the wires are lighter and more flexible than the 60-Core ones. They are also often slightly cheaper too.
On the other hand, 60-Core servo cables are used for higher current applications such extension for high power servos.
