Please note these are generation 1 cables that plug into stepper motors with a 6 pin JST plug (white plug).
spectrum stepper motor cables give your motors the cable length they need to run the distance of your slider while using them with the eMotimo spectrum. This is great if you need to mount your motor to one end of your slider. Pick up the length that matches your slider.
Please note, these cables typically won't work with other vendor's motors. If you have a stepper motor from another vendor, modification may be required as wire order varies.
