Taiss JST Crimping Tool,Dupont Crimping Tool,JST Crimper,Dupont Crimper,Ratcheting Wire Crimper for JST Connector XH 2.54mm,PH2.0,D-sub Terminals,(0.08-0.5mm² 28-20AWG)

I just received this crimp tool in the mail, and I couldn't be more impressed. I've decided to install some COB LED strip lights to augment the existing light in my new 3-D printer, and wanted all of the interconnections to be "OEM grade", including the JST XH connector on a new harness that will plug into the lighting circuit socket on the printer's motherboard. I'd bought a handy JST XH connector kit, thinking that I could crimp the individual sockets on the wires with a set of micro-pliers and then solder them. However, it quickly became painfully apparent that the tiny size of these uninsulated sockets coupled with the small gauge wire would make this a near-impossible task with marginal results at best.I immediately selected and ordered this ratcheting crimp tool after seeing a few promising reviews, since it seemed that this was my only hope to fabricate some decent wiring harnesses for this project. WOW...these things work insanely great, with each crimp looking like it had been done by professionals on a production bench! I did destroy a few sockets practicing with some spare wire, as it took me a few attempts to determine the exact orientation and very precise position of the socket in the crimper's applicable jaw slot. However, once this is learned, the results are amazing.I'm also very impressed with the quality of the finish and the excellent fit of the component's that make up this crimper. The crimping dies are machined precisely, and they're perfectly fitted and fastened on the jaws. There's a rotary dial to adjust the depth of the crimp at which the ratchet will release, but with the 26 ga. stranded wire and the JST XH sockets I'm using, the factory setting worked nicely so no adjustment was needed.Anyone who's made up a wiring harness of most any type can quickly master this crimper, although I'd strongly suggest having good lighting available and wearing a set of magnifying loops (plus readers for folks my age!) while making up connections given the really small size of JST sockets and pins, as well as the very critical positioning required when crimping.Bottom line: Very impressed, and highly recommended!

Purchased this for a breadboard project I was working on for PWM PC fans and Dupont connections. Crimp strength is ideal, if you dont know what you are doing you will destroy or over crimp the wire. Quality wise, it feels pretty solid.

worked well enough, needed some adjustment, passed pull test and measured height of crimp was in spec

Exactly what I needed. I had NEMA 17 motors arrive with stripped and tinned wires. Without a JST connector. So I ordered the JST connectors and these crimpers to add the connectors for my design. These were perfect for the job. Easy to use, and the ratchet was able to hold the connector in place while I inserted the wire. Durable, not cheap!

I'm doing a project that requires a significant quantity of Dupont connections. So I purchased the kit of connectors along with the ribbon cable. I also purchased this crimping tool. The tool is of excelent quality, very sturdy and tight fitting jaws. The issue that I had was that the size of the tool was too large to fit on the short tail ends of the cable. On a single connector the tool worked perfectly but trying to crimp the connectors on a multi-conductor cable was quite challenging.

If you are going to make your own JST-XH wiring setups, you are going to need a set of crimpers. Trying to do it with a set of needle nose plyers won't work. Just holding the metal end is difficult! These crimpers are well thought out, hold the metal end in place while you thread in the wire, and crimps it Exactly. They are heavy duty, well made and do a fantastic job crimping little bity connectors! They are for bare ended connectors like jst or Dupont type units. The crimping action takes almost no effort. Well done! These are not going to fall apart.

Seems to work well. The crimps look secure. Not sure if it was the crimper or the housing purchased, but I did end up requiring force on the back of the housings to get them in place. Given I can't tell where the issue is from, no stars lost to this. Loving the fact it clicks just at the holding point, has the force adjustability and a release latch, although I think the factory default is right on.

I've been able to use this on a few XH connectors successfully, but nearly every PH crimp I've attempted has not turned out. Despite what the description says, I don't think it's meant for crimping the PH 2.0 connectors.
