This is one pair of 4-wire cable with SM connectors. One cable has male SM connector and the other has matching female SM connector. The other end of each cable is unterminated so that you are free to solder them to other wires. Each cable is about 15cm long.
These cables are useful when you have 4 wires that you want to join and split from time to time. The SM connectors are designed with a latch to keep the wires intact when plugged but at the same time easy to unplug by pressing the latch and pull the cables apart at the same time.
You can use these cables when joining or connecting our LED strips and pixels as there are commonly come with 4-wire connection.
