The crimping tool is really fidgety. Here’s me getting it wrong.

Those closeups taken with microscope btw. The crimps are about 5mm long.

Next: gonna try crimping 22 awg (a bit thicker) stranded as other wire for same connector. Then actually plug in male connector and test continuity.

Okay, kinda got it right, but it was a bitch to shove it in which makes me thing I didn’t do the insulation crimp right or 22awg stranded is too much. See how I had to shove it in? (the connector end has a metal tab that ideal snaps in place for a nice irreversible join.

Good to know 🤣
I did try stranded 22 first, but it seemed to hard so tried 24 solid core just to get mechanics right. And yes I did use a crimping tool.

a) you can’t crimp solid core and b) you need a proper crimping tool. it should have hardened metal guides with two layers and be matched with the size of the connector

This is my crimping tool. PA-09 which seems to be the generic entry-level thing good for both JST and DuPont.

it should have a bilayer hardened metal thing with a ratchet for the correct force. This is more of a shaped pair of pliers and will never make a good crimp

I looked at the proper ones, including yours, before buying these, and damn they’re expensive. And I needed JST ones for my project and the good ones for those are worse. So bought these to make do.

I was going by reviews. Didn’t know how to pick and these PA-09s seemed to be recommended all over. It was about $40 I think and the jaws are hardened. But not the ratcheting kind.

Yeah I read about how these can do both conductor and insulator crimps at once. Sweet. I should look for JST ones.
