These 3-wire cables are 163mm (6.4") long and come as a set. One cable has a JST SM type connector plug on the end. The other cable has a matching JST SM type receptacle connector. They are good for whenever you have 3 wires you want to be able to plug and unplug. We like the solid and compact nature of these connectors and the latch that keeps the cable from coming apart easily. For more information, check the JST SM connector datasheet
Each order receives one of each connector. Wires are 22 American wire gauge.
