4 pcs/pack 2M 6.56ft 3 Pin JST SM Male Female Plug LED Connector Cable For WS2812B WS2811 SK6812 Symphony LED lights with connectors，SM3P buckle free welding plug light controller wire

I didn't have any of these connectors when I bought a water flow sensor whose short cable had one of these on it. I needed the sensor to be near the water, but I didn't want the Arduino that reads the sensor to get wet, so I used one of these extension cables to separate the two. The project took more work than I thought it would, so I disconnected and reconnected these cables a lot. They hold well while connected but come apart easily and they make reliable electrical connections. They aren't intended to be waterproof, so once the project worked, I wrapped the connection at the sensor with waterproof tape. They're still working fine.

The wire is too thin and it causes voltage drop. A short length of this extension cable causes more voltage drop than multiple full LED strings. I suspect the wire is 28AWG when it needs to be at least 22AWG. These are useless for my project because of the voltage drop.

Wow, these are very poor quality. I used them with some addressible LED strips, and the signal strength was very low. It looks like the wire gauge was smaller than it needs to be. I bought both a pack of two meter connectors and a pack of three meter connectors, and both were of the same poor quality.

Nice plastic ends, they interlock so you know the connection is good. You can plug into your main board by trimming the locking tab or you can remove the JST cradle from your board and plug this in directly. My package even included 2 male connectors with 6 inch leads. What is pictured is exactly what came. Great quality.

Good except for the fact that are the size of 6 pin connectors, and an entire row of 3 pins are just left empty. Meaning they weren't compatible with the 3 pin connectors I was trying to match them to.

I am trying to connect 2.. 2 meter strips with this extension between. it doesn't work. my second strip doesn't even light up. dont buy

These cables extended my WS2811 led strips for my battlestation. They fit great, they work, that's it!

Perfect for extending Xmas LED lighting, quick connect, low loss for power and signals.
