JST SM Connector 40 Pack, SM 2Pin Jack Plug Male to Female Wire Connector Adapter Electrical Cable for LED Light Strip 20 Pairs 10CM (JST SM 2 Pin Connector)

I used the VANDESAIL JST SM 2-Pin connectors (40 pack) for wiring my LED strips and overall it’s been a fantastic buy. The quality of the connectors is solid — the plastic housings feel durable rather than brittle, and the locking tabs snap in firmly so there’s very little risk of accidental disconnection. Every male/female pair fit together cleanly with a satisfying click, and there’s no wobble or looseness. The included wires are 22 AWG, which is sufficient for most LED strip setups (though I wouldn’t push them for extremely high current without checking specs). The insulation feels decent, not ultra premium but good for moderate handling. Using them was convenient: since they’re prewired, I didn’t have to solder anything — just strip, insert, and lock. The connectors make modular installations much faster and cleaner, especially when I need to section off LED runs or make custom lengths. For performance, I haven’t noticed any voltage drop or flickering in my LEDs (over several meters of strip), so electrical continuity is solid. The set includes 20 male and 20 female connectors, which gives me a lot of flexibility for future projects. Considering the price, this pack delivers excellent value, especially compared to buying single connectors or making your own wiring every time. If you work with LED lighting or DIY electronics, this connector set is a smart, reliable choice.

I got these for my LED strip connectors. With something like this there isn't really any middle ground. Either they work or they don't. These are working great.

Great set of connector leads for standard pixel lights. Fit perfectly and seem be of the same gauge wire as the LED wires themselves. Easy click to install. Easy solder connections to your power supplies and signal outputs. Great number of plugs for the money. No issues so far.

They are small and interlock tightly. Connecting and disconnecting is a bit tricky as you need to line up the (male and female) connectors exactly the only correct way. This is required to use both the locking mechanism, and to have the correct red and black wires match with each other, This one way only connection is a great safety factor for a positively correct wire connection every time. I will buy more in the future as required.

this was a second purchase of the same product great for small electronic and electrical projects

I used this for a small little project of mine - tweaking a USB desk light so it's control pad used different buttons. To make connecting and moving the project around a bit easier, I actually used these connectors to put everything together - they *mostly* work, but I find that wiggling the wires causes the LED to flicker. Noticed this not happening with some wires but not all... These are great in a pinch, when you are prototyping or learning how to build certain projects, but I'd say they aren't the best for any serious work. Quality might vary a bit more than you'd like.

This was the first time I received JSTs in the package and a couple of them were wired backwards. Because of this, I had a short in my wiring, the magic smoke escaped my project and I fried a microcontroller. Just double check your wires and make sure that the wiring on all these plugs are the same before you use them! Other than that, the plugs are fine, they all fit together and the ends are tinned which is nice.

Solid connection when joined, it won't pull apart without using the release clip. Very pleased with these!

Good quality, good price.

Muy buen producto. quizás más rapidez en la entrega

I used these connectors for wiring lighting on a G-scale train layout. The wires were a little thinner than I had hoped, but they were the correct polarity compared with wires I had purchased many years ago from a hobby shop (so no rewiring was required!). There was also one connector missing, making only 19 functional pairs, but the seller resolved the issue quickly. Overall I would still recommend the connectors as they are hard to source locally (at least for me) and so far they are working just fine. The connectors are exactly as pictured by the seller, so note the polarity if that may be an issue for you. The wire appears to be about 22 gauge. It is stranded, but the ends are tinned so they don't fray, making them easy to work with (although the exposed ends are short). All the connectors clicked together without issue and were solid. A good product at a good price.
