I'm not used to using the single position crimp tools, so I made a rookie mistake. I was using the correct size jaw to crimp the wire section, but then incorrectly using the next size up to crimp the insulation. In reality I should have been using the same size jaw for both.
After I'd made the video I applied several of each crimp with the basic iWiss tool using the same (1.6mm) jaw and it did a perfect job of them all.
It appears that the Dupont style connector termination tools actually curve the insulation grip around it, but don't bite into it. There's a very thorough guide to crimps and tools here:-

A search on eBay shows that Iwiss seem to do mainly crimping tools. If you search for the keyword Iwiss and lowest price first you'll find the IWS-2820 (28-20AWG) in the results.

These white connectors and contacts can be also found as NS25 series.
A good presentation of various low priced crimps. Logically if you are in the business of crimping lugs and pins frequently then you buy the top of the line tools. But for intermittent use the less expensive will suffice. I own both a five hundred dollar crimping tool and a twenty dollar tool and you can tell the difference when using them. One does prefect crimps every time with no fumbling and the other does take more time with the need to double check your work.
As you were saying "Of all the tools I've tested" They've been testing you Clive.😂
What an excellent upload..
Something to perhaps cover in a future video is the Crimps themselves.
It is a nightmare finding a decent tool to use on insulated crimps. But the crimps also vary
in my opinion and the ferrule which is crushed against the wire must be of suitable thickness
to remain crushed and in cheapo Chinese crimps this is not the case. Always buy good crimps
from RS or Farnell, they will not be be cheap but they will work. Chinese Crimps will nearly always
fail the pull test. You cannot crimp tin foil.🤔
Great comparison and description whats imporant. I used to make 200 crimps using the japanese tool. That was comparable to 6 month jail 🤣
Were is my flying Car. Tomorrow's World ? Mmmm
PS squeeze the side connector to make sure to make sure the connector goes into the plastic housing easily
Try taking a wire and stripping 1/2-3/4" off.
Then twist the wire then take the connector hold the wire and connector in 1 hand take neil nose pliers and squeeze onto the insulator gently only to hold it in place. Next make sure the bare wire is in-between the small inner wings firmly seated then crimp and cut off excess wire.
It is so much easier this way night day difference. Good luck👍
Most of those crimpers are capable of adjusting the crimp because of manufacturing processes and variables of the terminal ends . The star wheel with the stop screw is the location of the adjuster . 6/2/23
My projects involve terminal crimping maybe a few times a year, usually with a different terminal type than the last project. I feel like I figure all this stuff out every time – which die to use (I have an Astro 9477), which way the terminal is oriented in the die, whether the terminal barrel seam goes up or down… It is maddening! I would love to see you make more videos where you figure this stuff out and share your experiences. I really appreciated that you tested the strength of your test connections, because many of us hobbyists have small kits with limited pieces and don't want to waste them experimenting.
I took your advice.
I bought the IWS-2820.
My first 3 crimps were a success!
…
Off to the internet to buy more terminals.
🙂
Now do a video on a removal tool.
LoL.
Remove terminal from the housing sockets.
🙂
Cheers !
good info for choosing a crimp tool from china. thanks for the video, still relevant a few years later
This is a good video. I have crimped dupont-style connectors a couple dozen times. I recently started building a DIY RC car with my daughter. I hadn't used a crimper in years. I have a PA-09 engineer crimper, but I was absolutely crushing and distorting my crimps after the first couple tries. I think I'm just out of practice. I did get it to work OK after a couple tries.
I had to crimp some connectors onto a 6-wire cable for another project. I bought some 6-slot micro-fit molex connectors for this. I tried to use an SN-28B crimper from a cheaper brand (not iwiss) for these, and I was absolutely mangling the pins after my first couple tries. I think I was just using the wrong tool. I didn't really realize how much variation there is in the sizing of the ratcheting-style crimper dies and how critical it is to not mangle anything past the wings that are supposed to hold the conductor wire itself. I determined that I absolutely hate Micro-fit 3.0 Molex, and I'm going to use dupont-style connectors instead for this particular application.
Iwiss makes an SN-28B. These are supposedly for dupont style connectors. I think this is why you weren't having good luck using them on those JYK connectors. The SN-28B jaws are probably too wide for those.
In any case, My cheap set of SN-28Bs didn't come with instructions like those IWiss crimpers. I'm going to indeed measure the width between the 2 sets of wings on my connectors with digital calipers and also by eyeballing them in different positions in my various crimpers. It makes sense to me that you want a size that matches the width between the wings when parallel. I think I knew this when I last used these kinds of crimpers for electronic connectors a few years ago, but I forgot this detail. Thanks for pointing this out. I think this will prevent me from mangling connectors as my daughter and I try to finish building our DIY RC car next week.
Great video, found myself needing to re-crimp a video-door system power line, which was wired by a moron and duck taped together. I purchased a SN-01BM before seeing this video and pleased it worked perfectly, best 3quid I've spend in a while. And another tool for my collection. Domestically the connectors are known as XH2.54 at least here in China.
👍
Just had flashbacks of rotary crimping tools doing MIL STD type connectors. Of course the last person that used it misplaced the die that you needed the most.
The SN-01BM is sized for JST-XH and -XM connectors. The SN2549 does those AND some other sized (Dupont something or other) … so it's an SN-01BM AND an SN-28B on one die set
