Any thoughts on this crimp tool by Knipex, it has dies that can be changed.

I'm looking for an extremely high quality crimp tool that can handle automotive crimp bits (Ring, spade, splice etc.) and Dupont crimp terminals for PCB type housing/pin-outs.
I own that one (and the 5 inserts, for one insert there are two versions 97 39 13 ["A"]), and it is good for what it is, but there is no die available for automotive connectors that i know of or would recommend.

Actually "automotive" is all over the place, there are dozens of sizes and variants which pretty much require "their" special shaped crimp tool and as wiring harness manufacturers automated the process, manual tools are even more expensive as they are probably not using the same kind of insert. If you want to crimp according to specification you got to go with the contact manufacturer's tool.

Are these equivalent to "DuPont contacts"? Or AMP MODU IV? I find "DuPont connector" as suggestive as "Molex connector": there are so many, many of them.

I found this to be an excellent resource to understand the various types of connectors out there and many trying to masquerade as "DuPont" connectors (at least, the real Amphenol type). http://tech.mattmillman.com/info/crimpconnectors/

Also checkout tooki's various comments in https://www.eevblog.com/forum/reviews/affordable-crimp-tools-for-small-connectors-(dupont-etc-)/ as he really going into detail on which tools to get.  For Dupont (Mini-PV) connectors he's recommending SN-4228B off AliExpress.

Thank you for the link to Matt Millman's crimping contacts and tools survey: it has cleared up a lot of questions and tempts me to buy the Molex Micro-fit die I have been considering for a while. There are worse sins in life than collecting good tools. Right?

That's a great link, but apart from a passing reference to PIDG, it doesn't cover one of the most common types of connector, the ring/spade/fork/splice/etc connector, which TE (formerly AMP) markets as "PIDG", "Pre-Insulated Diamond Grip". (Of course, they're not the only manufacturer of these things.)

If you need a good crimper for these things, I'd like to give a shoutout to the TE 59824-1 TETRA-CRIMP, which can handle all common PIDG terminals as well as genuine FASTON receptacles (females), though not the FASTON tabs. Certain other manufacturers make you buy a different tool for each terminal shape (really!), but this one does them all, does it well, and does it easily enough that even a crimping boor like me can get great results. And it's even UL approved for all of the above, if that sort of thing matters to you.

Its only real downside is that, just like every other approved and guaranteed crimp tool, it's expensive at around US$320 from the usual suspects. ::)

Just to point out, this Rennsteig die is compatible with the above mentioned "ring/spade/fork/splice/etc connector".

"Crimp Tool Die, 0.5mm² to 6mm², 20-10AWG Insulated Terminals / Connectors (Red, Blue, Yellow)"
https://export.farnell.com/rennsteig/624-060-3-0/die-set-crimp-system-plier/dp/2518362?st=624%20060%203%200

Here's the tool body:
https://export.farnell.com/rennsteig/624-000-3/crimp-tool-2c-grip-burnish-0-8/dp/2517588?st=624%20000%203

Both come to ~US$210.

That’s because that page isn’t attempting to be a survey of all types of crimp connections. ;) The page title does say: COMMON WIRE-TO-BOARD, WIRE-TO-WIRE CONNECTORS, AND CRIMP TOOLS. (Sorry, I’m on my phone, not gonna retype to de-scream the all caps. :p )

The focus is clearly really on wire to board, and even then really only on smaller ones. PIDG and similar are far afield of what that page is about. (Insulated terminals are also generally much less fussy about the tool than small wire to board connectors.)

But honestly, I feel there is a huge need for a hobbyist-friendly cross-reference database of contacts, housings, tools, etc. of all sizes. Crimping is a minefield, and I think it’d be hugely useful to know not only what cheap tools work, but also what quality tools work for other contacts (the way that I use an AMPMODU crimper for DuPont and KK254 and clones thereof).
