BTF-LIGHTING 4 Pin Electrical Connector 24AWG IP65 Male Female Connector 7.87in/20cm Extension Cable for Car,Truck,Boat,Indoor/Outdoor LED Strip Lights/String 15mm Nut Small Size 5 Pairs

These are great. I’ve used them in the past with different amount of wires, perfect for a disconnect on motorcycles when hooking up auxiliary lights

I add them to my supply. They fit perfect for cooling and wet areas

Good news is they appear to be well manufactured and I can believe they will be waterproof I am presently testing them in freezing winter weather). I got the 4 pin small ones. What I don't like are design flaws: 1) the key which aligns the rotation is very hard to see and it doesn't stick out far beyond the pins so you can't just rotate the plug until the key engages. If you do you will bend the pin. 2) the O-ring which should be captured (but isn't) falls off if you are not careful and then it is not waterproof. At least it is orange and fairly easy to find in the dirt. 3) less serious is that the screw on connector cap between male and female is also not captured. Once you have soldered a wire onto the connector you won't lose it. After using these for 5 weeks I have upgraded my rating. All my previously stated shortcomings are still there but these guys survived 5 weeks exposed to 70 mph winds and subzero weather with sleet and snow. I have 80 connections and none went bad. Meanwhile external 4 conductor security wire got its insulation striped by the weather. I'd say these are a good buy and worth the minor shortcomings. For the alignment I just mark them the first time they are together with a metallic Sharpie.

A set of these previously purchased over a year ago have been in outdoor service for over a year without issue. That in in notoriously rainy Oregon conditions. I bought some for for a friend and projected future use. I would do so again.

I used these to connect my DSC wires from my VHF radio to my Multifunctional fish finder/Chart plotter. Since I wanted to be able to remove my electronics easily if needed, I did not want to have a permanent connections between the two devices. These four pin connectors were perfect. They are easy to install (need to be wired in) and are small enough to tuck up in small places. The are sealed and have a nice tight fit when connect to each other. The great thing is, if I need to take out my radio or chart plotter, all I have to so is un-screw the connector cap and easily pull them apart. Great product and you get plenty for other projects or if you mess up one.

Awesome to use,

- I can't fault the *quality* of these plugs; they are as described. - However, none of the descriptions are very clear unless you just happen to accidentally land upon the correct item. The reason I say that is, I need to make an extension with a PWM controller for some overly-bright LED string lights. The *wiring* is 22AWG. So I purchased these to match the wiring. - However, the *plugs* on these DO NOT FIT any of the transformer-to-cord plugs of that light string or any of my other various LED light strings. In order to get the correct size *plugs*, I have to get the ones with the 18AWG wire, which is larger. I don't know whether that size disparity will have a negative effect on the whole kit'n'kaboodle. So I thought about getting the larger size, but decided against it. - Frankly It should not be this darned difficult to find an extension for string lights, and for what standalone string light extensions cost, it would be cheaper to just buy a sacrificial set of string lights, which end up creating more unnecessary land-fill. - I'd just use a regular extension cord, except that I had wanted to include the dimmer, which must go after the transformer but before the section with the lights. - - There should not be such a big darned mystery about "extension for 2 pin single color LED outdoor string lights with transformer". I've seen a lot of comments by others who have been frustrated because things don't fit correctly, and so on. - In the end, it seems that the most straightforward thing to do will be to cut the original cord up near the transformer, and use these small-plugs-with-correctly-sized wire <!!!> to insert the extension that includes the dimmer. - I wish I'd known that in the first place instead of going bleary-eyed looking at page after page of unworkable cables.

Just what I needed. Fixed an expensive string of lights in about 5 minutes. Now have extra replacements when a cord end is a problem in the future.

Ich habe mir die 3 poligen Stecker und Buchsen zum Anschließen von Sensoren an Mikrokontroller bestellt. Die Stecker machen einen sehr robusten und hochwertigen Eindruck, die Enden werden schon verzinnt geliefert, nur beim Abisolieren hätte man etwas großzügiger sein können. Manche Stecker lassen sich etwas schwer in die Buchsen stecken aber durch die relativ großen Griffflächen ist das auch kein Problem. Mit dem Gewinde lassen sich die Stecker gut verbinden und sichern, fest angezogen sind sie dank des roten O-rings sogar wasserdicht. Die Länge von 400 mm ist für meinen Zweck perfekt. Den Preis von aktuell 8.81€ für fünf Paare halte ich für angemessen. Fazit: Fünf hochwertige Steckverbindungen zu einem fairen Preis, kann ich klar weiterempfehlen.

After some hunting finally found this vendor with the end(s) I was looking for. One of my 150' LED micro-light strands for outdoors had its plug break off the strand. Hated the thought of tossing the entire 150' feet and having to purchase a new strand ... so started to search for replacement plug (not as common as one would think out there). These were an exact match and easy to wire in and get the strand going again with no issues. And now I have spares as it will occur again as the elements make the wire sheathing brittle over time and for better or worse the wires will break ... sometimes by the plug but now I am ready to fix. Didn't seem as hardy as the one that was on the strand, but was an exact fit. Good product, and didn't mind paying a bit as it kept me from turfing a light strand only just over a year old.
