spectrum stepper motor extension cables are a quick way to add length to your current spectrum motor cables. They're great for going long distances. If you are extending your slider, distance from the Turntable, or just want to get creative with where you place your external motors, this is the answer. They are Male--> Female, locking connectors so just like a typical electrical extension cable, these can be daisy-chained.
How far? Really far.
We strung 25, 10 foot lengths together and were able to drive a slider with about 80% of regular torque.
