SN-01BM

I use this tool for crimping JST XH pins. I gave it 5 stars for ease of use but crimping these small pins is not easy; at least not yet since I am a complete novice to crimping those pins. Positioning of the pins in the tool is the difficult part. Once that is accomplished the tool operation is easy. I also purchase a kit with pins and connector housings. Many of my first crimps were near failures in that the retaining tab was crushed back into the pin and I had to dig it out for the pin to function. I also purchased pins from a popular electronic components company that worked much better in that there was more clearance for the retaining tab to be clear of the tool for the crimp. There was also more spacing from pin to pin on a string of pins. Keeping the pin on a short string rather than breaking the pin off an then trying to insert it into the tool makes pin insertion more manageable. The slightly wider distance between pins helps.

I do a lot of automation work using Arduino and Raspberry Pi for things like sensors, fans, etc. I'm OCD about having perfect cables/connections. I have tried five crimp tools and even after dialing in the right crimp pressure and inspecting every crimp and making sure the insulation crimp was flat but often have the last insertion in the housing blow out the sidewall of the housing or ruining the crimp trying to force the pin into the housing. I read an article the other day on hackaday.io about using the proper tool for the job and the author recommended the $425 manufacturer's tool for the perfect crimp. Way too expensive for my needs. Realizing that, he recommended this crimp tool as second best. It turns out, most low cost crimp tools form an elliptical crimp making it hard to insert the pin into the housing. It also seems to spread the sidewall of each position out so the last position would blow out the side wall. The uneven force of an elliptical shaped crimp can also increase the resistance of the connection. This crimp tool is different in that the shape of the jaws makes for a more circular (cylindrical) crimp even on the insulation part of the crimp. I received this tool yesterday and this morning started to make some test crimps on 26 and 28 awg wires. When I pushed the pins into the housing, they just slipped in so easily I couldn't believe it! All of the latches were evenly closed which I sometimes had to live with questionable latching if I knew the connector wouldn't be disturbed and not have anyone pulling on the cable. When I flipped open the latch, the pin slid out as easily as it had slid in! Although it might not be the "perfect" tool for dupont connectors but I didn't have one bad crimp in all of my test crimps.

This crimp tool is listed as suitable for the Molex KK254 terminals (Molex p/n 08-50-0114). But it's not really good for those. The die is not wide enough to encompass both the wire and insulation sections of the terminal at the same time. So either you get a good crimp on the insulation or on the wire, but not both. So then you have to shift the terminal and crimp again. This often results in the terminal being bent or otherwise deformed so it won't slide easily into the Molex housing. (Example: Molex housing p/n 22-01-3027) I gave it 4 stars because it's a really nice tool. It's slick. The ratchet and everything work really well. It's just not suitable for the KK 254 terminals. I returned it. I'm still in need of a crimper that works with those.

I use the Iwiss crimper tool with the SN-01BM die to crimp the pins for JST XH 2.54mm connectors, using 22 AWG stranded wire. It works extremely well. The fact that it crimps in both places (the wire insulation and the wire, which are different sizes) simultaneously, which means you don't have to crimp twice, is very convenient. The ratchet feature is also very convenient. The tool also releases automatically as soon as it's delivered the precise amount of crimping force so you don't have to think about that. Specialized crimping tools used by professionals cost hundreds of dollars (some even more!). This tool is under $25 and it works perfectly. There are so many types and sizes of connectors and tools that you have to select the right tool for your connector. Assuming you've done that, you need to learn the right way to use it, e.g. which way the pin goes in the crimper, where to place it, how much insulation to strip off, proper wire gauge, etc. For those folks who say they haven't had a good outcome with this tool I can only imagine that there is some detail like the above that they haven't attended to.

I have several different sizes of iCrimp ratchet crimper tools. This one is the smallest of the set and has been used mostly for Molex micro terminals. Provided that you select the right size anvil holes for the terminal and the wire used, the result is excellent. I've wired a bunch of connectors with these, and they are still performing well. The tools are solidly built and smooth in use.

Used this for making solar panel wires. Works great.

Spot on for making up your R/C servo control leads using Dupont connectors. Using it to make up leads for my MegaPoints system for the model railway.

Ottima pinza, fa il suo dovere senza problemi. Unica avvertenza: meglio se usate una base per lavori elettronici con pinza per tenere ferma la testa del cavo nell'alloggiamento: farlo a mano per aria è difficile, viste le dimensioni.

im sure if you spent $400 you would get a better crimper for speed crimping, but if you take your time and do things slowly (and you have the correct wire gauge and insulation thickness and matching crimp bit), you can crimp every connector (I had to cut a portion of the insulation in some of my wires because they were 600v rated, so the insulation was extra thick). releasing the crimper using the little nib can be difficult, especially after you put in too much force and you need to bail, you need to crimp down on the crimper a little bit so that the tension can make the nib easier to move, but I had to use a random tool to push the nib since there isn't enough space for your fingers.
