Affordable crimp tools for small connectors (Dupont, etc.)

<< < (18/32) > >>

TheBay:
I normally don't cheap out on crimp tools, but I needed to do some Dupont and JST connectors and bought a "Preciva" branded crimp tool as I could get it next day on Amazon. All I can say is wow it exceeded my expectations and does a perfect crimp every time.

gatoruss:
I know this is an old thread, but is the SN-4228B and the TZ-4228B the same device?  Both are offered thru Alliexpress.

thm_w:
Looks the same to me, the first one even shows "TZ-4228B" in the photos.

It was also asked earlier in this thread.

sleemanj:
With those SN and TZ from Ali you'll never know what you are getting.  Who knows how many manufacturers there are of them, probably some are great, and some are... not.
 Always be sure to read the customer reviews at the very least.

I stick to my assessment that the Iwiss 2820M are the best bang for buck in hobby crimping, not fancy, and technically "the wrong shape" as described in this thread, but they are cheap, well made, and work reliably with just a little practice.  They are the ones I reach for in my draw, not the couple pairs of different ratchett ones or other manual ones.

Except with the rarer types like the 4228B and SN-25, which seem to have one, maybe two companies making them.

I am inherently skeptical of non-ratcheting crimp tools due to the uncontrolled crimp force.

At some point that isn’t now, at 1:20am on a work night, I need to write a proper update. But in a nutshell:
The official AMPMODU MOD IV tool I got for cheap is, by a wide margin, my preferred crimp tool. I use it routinely for DuPont and KK254 crimps, and the results are just gorgeous, with the least effort by far.
Next favorite is the IWISS 3220M. It’s basically an SN-01BM, -02BM, and -03BM (i.e. various size D-sub) rolled into one linear action tool. Of the tools I have, it does the best on JST XH and similar.

I also managed to snag, after having a saved search for years on the local classifieds, a DMC AFM8 military crimped (for machined, circular contacts). A joy to use, for things where a circular contact is available. (So completely irrelevant to this thread. :p )

I picked up a used Molex Mini-Fit Jr. tool. It’s neither intended nor suitable for DuPont. With the locator removed, it can be cajoled into making some VERY nice KK254 crimps, but positioning the contact in the tool to do so is an exercise in frustration.

At my previous workplace, we ordered the $125 Molex KK254, etc. tool mentioned above (64016-0201). It was… bad. Decent handle, but cheap cast dies that did not line up correctly, producing consistently disappointing crimps. And the included clothespin-looking thingie that is supposed to pass for a locator is a joke. It’s fiddlier than just holding the damned contact by hand. We requested an RMA from Digi-Key and they just refunded the money and didn’t even want it sent back.

At my current work, we have a semi-official Mini-PV tool. (Semi-official in that it’s a tool from an expensive manufacturer, made specifically for Mini-PV, but not from Amphenol. I’m quite certain the actual OEM is WEZAG.) Unsurprisingly it works perfectly on the female Mini-PV contacts it’s designed for. It’s very difficult to use it for male mini-PV, however, as the die shape relies on the locator to prevent rotation of the contact, so when not using the locator (for the male pins) it’s fidgety. Real Mini-PV contacts, both male and female, have much wider, more open insulation crimp wings than the Chinese DuPonts. Easier to insert fat insulation into, but harder to crimp without a locator.
