A pigtail cable has a JST-SM connector on one end and open wires on the other end. An extension cable is used to extend an existing JST-SM connection, normally with matching connectors for plug-and-play wiring.
JST-SM Extension Cable Series
JST-SM Extension Cable Series
The JST-SM Extension Cable Series is designed to extend the connection distance between LED strips, LED rigid bars, LED modules, controllers, and power supplies.
Unlike pigtail cables, this series normally includes JST-SM connectors on both ends, making it suitable for plug-and-play extension in LED lighting systems. The current file includes 2Pin, 3Pin, 4Pin, and 5Pin JST-SM extension cables, mainly with PVC insulation, tinned copper conductor, 20AWG wire, and 1000mm standard length.
This series should be separated from pigtail cables because customers use it differently: pigtail cables are mainly for soldering or open-wire assembly, while extension cables are used for extending an existing connector-to-connector connection.
