100 Sets/400 Pieces 1.25 mm Pitch 2-Pin Electronic Wire-to-Board Connector Adapter Cable Assembly Male Plugs, Female Sockets Housing and Crimp Terminal Kit Compatible with Molex Picoblade.

I have no fancy equipment to verify that these connector shells and contacts are within the allowed tolerances of the JST-XH specification, but what I can say is that the first 10 crimps I made - attaching female pins to 24 ga wire - went smoothly and flawlessly with an IWS-3220 crimp tool (1.6 mm slot). Insertion of the crimped contacts into this kit's 2 pin shells was easy.The goal was to shorten cables from 8" to 3.5" on five 4020 fans (2 wires each). The shortened cables all mated securely with existing circuit board JST-XH sockets, and the fans worked fine. For under $10 the cost of this approach (maximum $2 per cable, completely discounting the excess shells and pins included) was worth it to me.One caveat; if you don't already have a crimp tool you would have to include that cost along with potentially "wasted" consumables as you learn to use it. Fortunately the cost of many crimp tools has become quite reasonable, even for occasional use.Of course, with a project involving only 10 wires and contacts are cheaper solutions - such as keeping the existing cable end connectors, cutting out a section of the cables, and rejoining the wires with barrel crimps or perhaps solder with heat shrink insulation. However, with these methods the very short cables would not be very flexible, nor would they look very good, IMO.Several different crimp tools are available that accept these contacts. Fortunately the one I have (noted above) works well with the contacts in this kit.The other connectors included (i.e. the remaining 2 pin, as well as 3 and 4 pin ones) I won't use right now, but for the price it is like getting them for free, and I've no doubt that eventually I'll put them to use. They store nicely in the provided plastic box.Overall for my small job there were no problems at all, other than ensuring up front that I was ordering the right JST connector variant (-XH in this case) to match my existing components, so 5 stars.

I bought these for some audio cables that I needed to be able to disconnect. They should work as well for low voltage (e.g. 12v) connections if you take your time and understand the limitations of the kit.The first thing was that the size was good (no issues with real 16-18g AWG multistrand wire). Many of the other options I looked at claimed to work for 16g but really only worked for 18-22g. These DO take time to put together and I recommend crimp+solder to be safe. I actually use crime+solder+heatshrink, but the last bit may be overkill.The connectors themselves are simple snap/click connectors. Not much to say there other than I didn't see any come apart and the plastic was pretty durable. It reminded me of the plastic I used to see on Molex style PC connectors. It's a little flexible, but still stiff enough to push into place. Because I was using these on an audio setup my concerns there were that they made a solid connection. Time will tell, but so this has been a good choice.

Pins are pretty cheap and not very uniform but sufficiently good for low amperage applications. You have to cut them off a strip of pins. Connectors are extremely basic but work well enough.

Accurate description, good price for a hard to find item

These crimps are not interchangable with some cheaper "XH" crimps I had from an all in one (crimper included) kit from Amazon, but I think these are higher quality. They are easy to crimp and work well. I normally use an Iwiss IWS-2820M to crimp which is a very good tool, but I'm pretty sure even my cheaper ratcheting crimp tool worked ok on these. Highly recommend this seller for crimp connectors.

works well

If you need JST SM 4 pin connectors these are great. Especially if you need 50 connections all at once. But the packaging is terrible. You have to take out ALL of the connector sets in order to take out/put in the connector pin reels. This looks like a small shop put the product together based on the DIY labels and generic plastic container. Fortunately I had an empty flat container from other connectors that I use.

Used this product to add connectors to 3D printer parts and LEDs. No issues with how they work, I just really suck at pinching them together and I think I bought the wrong tool for it, but that is a me problem and not an item problem. It can be a little difficult to get the fittings correct without a jig or helping hands or being an octopus but once you get it set, they work well.

It is what it is not easy to fail at that, but it's the best packaging I ever received for that kind of product!

Perfekt für kleine Dinge in der ElektronikPassgenau und SolideSehr gutes Preis Leistungs verhältnissKann ich nur empfehlen

Bon matos et pas cher et livraison extrêmement rapide, je recommande.N’hésitez pas, vous ne trouverez pas moins cher ailleurs.
