content: What type of connector and pins is this?I would like to replace the existing cable with the shielded cable. What type of connector and pins is this and does it need any special tools to make a connection. It doesn't look like a Female Crimp Terminal pins and is there a trick to remove the metal pin from the housing. In the worst case, I can buy new plastic housing.[ Specified attachment is not available ]

content: Bog standard "JST style header" I believe. Which is incredibly nonspecific, but generic enough that it works, go figure.Tim

content: I also think it's a JST or copies of JST connectors. If I remember correctly, they come in 2mm, 2.5mm, and 2.54mm.If it's less than 3 pins, you can force 2.5mm to 2.54mm or vise versa. But if any more than that, it just won't fit.

content: You can easily find these connectors searching for "XH2.54 connector" on eBay or Aliexpress.I keep one of this sets around:https://www.aliexpress.com/item/32760531736.htmlit's very handy to have.To remove the terminal from the housing you just need to push the cable a bit and then use a screw driver or exacto knife to press the small lock down and bend it.To crimp a new terminal on the wire you would need a crimp tool (for the cheap ones search for SN-28B), something like this:https://www.aliexpress.com/item/1005003170794927.html). The problem is, each terminal needs a specific die. I got a few different types of die for my crimper but none are compatible with XH2.54 connectors so, in the end, I just use a long nose pliers and some solder, not great but it works.

The SN-28B, despite being the most commonly sold, is a poor choice for nearly all small connectors used by hobbyists. It’s designed for 2.8mm spade connectors. It’s not suitable for DuPont, XH, PH, or Molex KK-style (e.g. the common KF2510 clones), as the jaws are much too thick.I have a roundup of small connector crimp tools (and links to other resources) here:https://www.eevblog.com/forum/reviews/affordable-crimp-tools-for-small-connectors-(dupont-etc-)/Soldering XH connectors is a really, really bad idea because of the fact that the contacts come right up to the back of the connector, so there’s no strain relief at all. Soldering the wire means you’re likely getting some solder wicking up, so the weak spot will be right at, or above, the connector body.

content: Quote from: T3sl4co1l on December 09, 2021, 06:16:16 pm”JST connector” alone usually means the JST RCY power connector. It’s best to use the actual names, like XH in this case.

content: Quote from: langwadt on December 09, 2021, 10:06:15 pmIt’s an XH. PH looks very different.Quote from: tkamiya on December 11, 2021, 12:47:47 amThe 2mm connectors look different, and they don’t make them in 2.54mm: XH is 2.5mm. For inexplicable reasons, many Chinese vendors call them XH2.54, but they are 2.50mm.

content: Quote from: tooki on December 11, 2021, 01:38:08 pmYou are right, the 28B die is not compatible with the XH connector and won't crimp it properly, it will just smash the terminal. I was just suggesting the term to use in the search as SN-28B or SN-48B will give the most related results. The crimp tool is the same but the buyer will have to select the right type of die. In the link I posted the seller lists an option that would be compatible with XH and KF2510 terminals.Quote from: tooki on December 11, 2021, 01:38:08 pmYes, I knew it was a poor advice. Having the right tool for the task is invaluable and I think the $20 well worth it for the time it saves, even if it's to crimp just a few terminals eventually.

content: Quote from: Microcheap on December 11, 2021, 04:44:11 pmExcept that giving the “most” results isn’t useful, as practically all of those results are for the wrong tool and thusnotrelevant.* Why not just search for “XH crimper” or similar? Even with that, onestillhas to wade through tons of irrelevant results, but it’ll be fewer.*this “logic” is what leads Chinese vendors to stuff product listings with incorrect keywords, thinking that “all views are good views”, not understanding the value ofaccuratesearch results.
