Im sure that there is a real way to figure out 1.6 and 1.9 … but I just screw up a few every time to get started…

When crimping a JST pin, leave it attached to the collating strip. Use the collating strip as a handle, and break the pin off AFTER crimping! MUCH MUCH easier!

Hi, great article!

How do you know to use the 1.6 for the wire crimp and the 1.9 for the insulated part of the wire?

Is it a test and see what slot fits the connector?

I’ve had good luck with the IWiss Crimpers though my biggest problem is I don’t get the wire in far enough or too far in.
I probably need to make a wire ruler and mark exactly how far the wire goes in for each different connector.

But I’ve seriously am considering the Engineer tools you mentioned and only do one connector at a time.

Great and informative article. I appreciate the work, information, and layout. Frustrates me when I am looking for information and I have to filter through 3 paragraphs (or 10 minutes if it is a video) of introductions and backgrounds before getting to the meat of the subject. If the contributor needs to stroke their own ego, then do it at the end.

However, you went immediately into what brought viewers to this article in the first place. You also clearly and intelligently divided the article into sections, giving the reader the ability to go straight into what was most important to them.

I have been using MOLEX, Dupont, and JST-VH pins for a long while for connections on Duet 2 and 3 as well as custom cables for PC enthusiasts. I have always used a ratchet tool that crimps the wire and insulation barrel at the same time. I just introduced a new tool board that uses these connections across most of the board. Your article has been a lifesaver. I just ordered the proper tool and also decided to switch from the 12 62 180 SB to the 12 42 195 that you featured here.

Again, thank you for the information and the work performed to present it in an awesome way.

I tried a few “cheap” tools then purchased the PA09 back then they were over $50 + Shipping. I came across IWISS IWS-3220 a few years ago and was amazed, the jaws are stepped so it only takes one crimp, after you set the connector into the jaw and squeeze gently they lock allowing you to insert the wire without worrying about the pressure on the handles and a big item is the notch on the connector that locks it in place, they catch it and hold it outside of the jaw. Just did another batch of XH connectors, perfect. I liked the IWISS tool so I purchased their PEX pipe crimp tool, another winner, I can get into areas my other tools can’t. Oh, 50 was fun, wait until you’re 72…

This is an excelent tutorial and I wish i could have found it before learning under the “School of Hard Knocks” methodology. Kudo’s to you and your time and patience to do this.

Never accept that you can’t figure it out.
Keep on digging.

Thank you… honestly I was beginning to think it was just me… I have a drawer full of crimpers and a new pair arrived yesterday from Amazon because I was not willing to give up on crimping those little JST pins. I 100% agree, buy pre crimped but there are always times when you need that one special cable or some special length and I really wanted to master this… The one yesterday came with Dupont assortment and JST assortment and SN028B crimper. I will admit the Sn028B crimper works AWESOME for the dupont connectors. Doesn’t work worth dung for JST. Being the stubborn type, I see a PA-09 crimper in my future. If I can’t crimp nicely with them I won’t blame you, I will know its me at that point and give up!

Great post.

Thank you for making this guide. I was able to crimp 4 connections (in 5 attempts) using your instructions and this crimper (which is a bit cheaper).

(I also bought some pre crimped wires, but was able to get the job done before they got here.

Solder the wire… yes… as you say that is sooo sooo wrong. I have done it a few times… but it ALWAYS ends badly.

In reply to Dan.

Yes… I just re-read what I wrote and I am not exactly sure which place I didnt say male/female… But as Dan pointed out some/many/most of the connectors you only crimp the female part of the connector… and the other side is meant to be soldered onto the board.
