This is a 72″ ribbon cable made from 10 26AWG conductors. While this is a standard gauge ribbon cable, it is a bit hard to source. We do recommend this thinker gauge instead of the thinner, more common 28AWG. The 26AWG is more efficient and will not generate as much heat. The connectors at the end are keyed so that they can not be plugged incorrectly. This length of ribbon cable can be used in the 18″ x 18″ and 30″ x 3″ configurations.
