I had been trying this an odd 20 times now watching other videos, but I could do it on the first try after watching this one. Very good job on showing exactly how its done and how its supposed to look like afterwards

[@PoolCNC]

One of the best videos over JST

[@fazzah777]

I've watched many videos like this, and yours is the first to show that the band actually serves a very important purpose in crimping these little connectors. I had many failed attempts because I removed the connector from the band and then tried finding the sweet spot on the jaws. Your method is so much easier!

[@leso204]

The mistake a lot of people make it's there for a purpose ..............

[@gregsexsmith3066]

Thanks for the great video. After watching others and not getting it right I watched this video and got it right the first time. Keep up the great video. Thanks for your help!

[@mikaelbackstrom]

Thank you so much. Been trying now and then for 1 year, and finally it makes sense. Thank the Gods that I am smarter with other things. :)

[@mracousmetre2263]

Excellent tutorial! Calmly and very well presented.

[@witektaaham6297]

Thanks. Great for getting started. I am happy to find this video here.

[@jayoli7073]

SUPERB VIDEO and EXCELLENT explanations!! WELL DETAILED!

[@Dissocioo]

you literally saved my project. THANKS !

[@mikewhite2991]

excellent! love the zoom views, helped me a lot!

[@carriep7812]

Really great job at explaining this process - and at the video in general! Thanks for sharing. I just purchased one of these crimpers with the connector kit. I hope to be making some 5-pin cables soon.

[@marksatterfield3100]

EXCELLENT tutorial. Thank you Sir!

[@Johadart]

Hi there, just like to say, from all the how to videos on this subject, yours is by all means the best, in explanation and in showing how to, great work, I’m a new subscriber now. Cheers 🤙🏼🇦🇺 Joe from Australia 🤙🏼🇦🇺

[@michaelgrier]

Great video. I have a different brand set but same basic deal. Other videos are blurry or say I need a thinner crimper to crimp the two sections independently. This is great and I’m now going to go ahead and make my first connector with high confidence that it will just work.

[@FransvandeKamp]

Nice tutorial with good information and very nice close-up

[@ProfBab]

6:06 "There are 2 different heights of crimp" - Dude, i never noticed it 🤕. I did this the other way around and every time it sucked. Thank you!

[@LeoJablonski]

Thanks very much! Your video is quite informative. I'll do my first (proper) JST crimping this weekend,

[@n0k1parkour]

the best vid on this theme! thank you a lot!

[@ihazabike]

Thanks for this! I could not figure out how to properly use these crimpers. I wasn't even close!

[@jaisonmendez4656]

Hi, Thanks for the video. You are a good teacher. Bravo..

[@peppiino]

Thank you for the video! I learned much!

[@randomtronic]

You are welcome! Glad you found it interesting!

[@UpcycleElectronics]

Thanks. This is exactly what I was looking for. I wasn't sure which pliers/jaws were the correct ones for rolling the tabs to bite into the wire. ...don't do this manually... I made my first 5p connector without the proper tool. That was a solid 45 minutes of tedious frustration :-) -Jake

[@MCsCreations]

Fantastic, dude! I need a kit like that, but with different JST connector sizes! To use for rc in general. 😃

[@user-gb5xq6jh8b]

Thank you. Nicely done. Quite helpful.

[@steveu235]

Very good tutorial well done thank you

[@augustgrasl6661]

Das schaut gut aus! Das merk ich mir. Gleich gekauft!

Great video!

[@certified-forklifter]

this video is awesome. thank you

[@javierpallalorden]

Nice crimp tool for home use.

[@user-yk1cw8im4h]

Thanks, really nice video

[@barrygreengrass3379]

Chris, thanks for doing the video for me, I contacted the seller of these crimping pliers they do not sell any other dies for these pliers, that’s a shame.

[@randomtronic]

I don't think the manufacturer sells them separate. You will likely find different crimpers as a complete tool, but not the dies themselves.

[@andreafalconiero9089]

@@randomtronic This is an SN series crimper, and you can find other dies for them on AliExpress and elsewhere. For example: www.aliexpress.com/item/4000107781474.html

[@TomFYouTube]

You did a great job on the review!!! I subscribed. I received the IWISS SN-2549 to do JST-XH connectors a couple days ago but because of where the JST-XH crimp is located it was hard for me to get the connector in there with my fingers. I will be returning it today and getting the IWISS SN-01BM... On a side note It would be great if you did more reviews and tutorials on Radio Control related items and proceedures like crimping and soldering. Again I like the way you explain everything and the way you made the video. Great Job!!!

[@randomtronic]

Thank you for your encouraging comment! This really means a lot - sometimes I loose faith in KZbin due to getting lost in the sea of content, but you just have refilled my motivation reservoirs to full! 👍

[@TomFYouTube]

Hang in there!!! GaryVee (Vaynerchuk) went for 18 months creating KZbin content nearly every day before any significant people started watching. He didn't give up. Now he runs a multimillion dollar marketing firm. He and his family is originally from Belarus... kzbin.info/www/bejne/hYWrk3mYZsuBr5Y

[@superpooper_2030]

SN-2549 is combination of SN-28B and SN-01BM. SN-2549 is multi purpose crimper but I have both where I bought both for less than US$25

[@michaeltyers7336]

I have that exact same crimping tool and it was doing an aweful job for DuPont connectors! Now I can see it was never designed for DuPont and that's probably why it was doing such a horrible job. Thanks for video.

[@rwpresley]

Excellent.

[@MadHatter764]

Good video tutorial - the ebay link is broken/stale but I was able to search for "900 pcs jst" and found similar kits.

[@slybunda]

sellers say the SN-28B and SN-48B but its the wrong one. this SN-01BM is the correct one for dupont and jst connectors.

[@I967]

Exactly as you say. The SN-28B crimping pliers are NOT FOR JST-XH connectors. I also got the SN-28B in a bundle with Dupont mini-PV and JST-XH connectors, as a one set - two boxes of connectors and the crimping pliers. I test tried to crimp both the Dupont mini-PV and the JST-XH with SN-28B and both of these came out mangled. The mini-PV came out so-so, but it got stuck in the jaws of SN-28B and the JST-XH was completely crushed.

[@InobuZ]

There are a lot of variables that one must take into consideration. For example if you are heavy handed (Breaking things) you want to use the ratchet type. If you have a good feel for things then the manual one will work. The smaller the connector the lighter the incremental squeeze. The quality of the dies is what causes the pin to curl back on itself. If the die are jagged you will not get a good crimp causing you to re-crimp and smashing the connector pin. XH's are large enough that the crimp threshold does not matter. Some of the connector (SH) requires a microscope to set up the crimp. Without it its a waste of time. Those type requires a high end die like Engineer PA series. That last thing you need is your drone flying off into the sun set because you want to prove that a cheap knock off works just as good.

[@carolbaverstock6063]

Thank you! I appreciate your clear teaching.

[@superdau]

You are lucky that your crimp tool got decent dies. I ordered one (for the "dupont" style connectors) and in what I got the dies are so inaccurate that they just crush the connectors instead of folding the tabs. The dies seem to be cast metal without any further machining. I had seen those dies previously on pictures (they are usually the painted black ones) and imagined that they couldn't work well. That is why picked a more expensive seller who showed grey/shiny metal dies (which are either machined or at least somehow treated after casting) on the product images. Still got the crappy dies. So everyone thinking about getting a crimping tool , watch out for that.

[@green323turbo]

good magnifying camera

[@garynorris4648]

Nice

[@youssefdirani]

nice note for the 2.5 not 2.54, who would had noticed ! :)

[@carriep7812]

So I too got these crimpers but am not having very much success. I believe it is because my pieces are a bit shorter then the ones in your video. The end which must stick out with the tab to keep it in the plastic housing, gets crimped way too easily! I am able to get one successful crimp out of 10! Maybe this is why there are so many included :) But seriously, would you please share where you got your terminals? They definitely have some slight differences from mine - and it appears that you have that extra 1 - 1.5 mm in overall length for your terminal to clear the other side. Thanks, Carrie

[@Scorpade]

I have exactly the same set and all is explained very. However you can leave out the stripping of the wire. This is because during crimping you are piercing through the insulation

[@randomtronic]

I thought it should be ok without stripping, but it seemed that stripped wire will give more reliable connection. Thanks.

[@jaytee3287]

Very interesting, I had never considered doing it without stripping the wire first. This would make it less tedious for me, thank you for posting this tip. Also thank you to the video creator, this is the video I first learned how to crimp from, it's by far the best tutorial for crimping that I ever found

[@randomtronic]

Thank you for your kind comments!

[@ericgooding1317]

Dracula doing crimps. Rad.

[@certified-forklifter]

how much awg was that wire please? thanks

[@TheMechatronicEngineer]

Does this work even with solid core wires? Cheers

[@leemarson7350]

Nice instructable video. I didn't know about these types of connectors until a few days ago. I was looking at crimping methods for connecting LED Strip RGB extension cables together. I would still like to have done it this way although I am not sure how? Instead I am opting to use gel filled butt splice connectors. Can you use these types of connectors cable to cable instead of for circuit boards?

[@randomtronic]

Thanks, and yes, there are male and female connectors for cable as far as I know, just not as common.

[@Kotofosonline]

What difference between SN-02BM and SN-01BM? Which is better for JST PH?

[@siddharthmali5841]

Great

[@Kurt634]

When you say easily fixable at 8:14 what do you do off camera to fix it? Whenever I crimp the insulation too far in like that I've always just had to cut the end of the wire off and start again (also wasting a connector because it's stuck to the wire). Thank you for the video!

[@ChadLuciano]

That's the fast way...if you are on your last connector and need it badly you're going to have to squeeze it back open and probably cut yourself in the process.

[@10_dewagedea.a.74]

On the hole pcb, is that male jst or female jst (?) 8:42

[@ianian8797]

Dunno why, but when I do it it just flattens the entire piece of metal.

[@youssefdirani]

I don't use a tool, and solder them, use cutting pliers and long head pliers. A mess but very effective.

[@UA_RC]

SN-2549 not suitable for HX2.54 JST -it fully placed inside crimps, what you use?

[@oldfoxian]

You can try it, if it's not too late)) SN-01BM aliexpress.ru/item/33050785057.html?spm=a2g0o.cart.0.0.22ab3c00Zdsl39&mp=1&_ga=2.125895246.252102886.1608753472-934956076.1604938860 Hi, from Russian

[@carlosgarcialalicata]

Half of my wires are broken after crimping, and the rest break as soon as I move the connector a bit

[@burlingwoodau7277]

what's the difference between XH and PH? is it size of crimp? are they compatible?

[@paulseamons1380]

The XH crimp is 2.5 mm pitch and the PH is 2.0 mm pitch. No, they are not compatible. By the way, this video gives very poor crimping instruction, I would reject every crimp that was made on those tools. Without the manufacturer approved tooling, you would be safer soldering the wire into the terminal. (Application Tooling manager at JST UK Ltd for 35 years).

[@MrBlowmyselfup]

@@paulseamons1380 got a good video on how to crimp correctly?

[@klazzera]

engineering brand ones are much more expensive and don't have the ratchet mechanism

Это не JST!!! У JST шаг 1.25 идёт.
