Hello all, I am looking for help identifying a confirmed working crimp tool, or class of crimp tools, for this Pomona part:
At the moment I believe the appropriate tool is a crimper for uninsulated, closed-barrel terminals, such as Klein 3006CR or similar (which I do have) – the kind of thing you would use to crimp ring terminals, spade terminals, fork terminals, etc that do not have the red/blue/yellow vinyl or heat shrink shrouds.
I sent a support request to Pomona directly but the best they could do was direct me to a brand (Paladin tools.) One person has suggested to me that they may have meant to imply the Paladin PA8049 but this is pricey for me for something that is an off-label use (it is meant for coax connectors) and no one has confirmed actually works.
I have spent this morning removing the insulation from a half dozen various kinds of insulated crimp terminals, and going through my collection of ferrules, combining ferrules in layers, etc. to find anything that has a similar dimensions and amount of metal to compress. After all that, the result has been inconclusive as to whether the 3006CR would work here.
If it helps, the barrel to be crimped is machined (no seam), nickel plated brass, 3/16" long, 0.094" OD. It is not specified but based on measurements the ID is approximately 0.050" (~0.020" walls.) I am trying to crimp to 18 gauge stranded bare copper or tin-plated copper wire.
I too am not seeing that there is a confirmed working / compatible hand tool for these.
I would agree with Hearth from the other forum that the hex type crimp would probably be the better option. As the 3006CR seems more for the stamped type of contacts you can find for say the quick disconnects.
PA8049
Thank you @Nathan_2268 , I guess that is two votes for this style now.
Just eyeballing it, I assume I would use the location marked “0.068” on this crimper, assuming that is the width-across-flats of the hex shape it makes. Does that seem right?
I am a little lost on how I am supposed to arrive at this tool from the phrase “bare-terminal style crimper” in the datasheet, and have confidence that 0.068" is the correct measurement and that the die jaws are less than 3/16" thick but not too thin. I understand of course that you do not write the data sheets for your vendors – just if there are clues I am missing I would like to learn.
At the moment I am guessing that folks with more familiarity with coax crimping than I have are recognizing the connector as being similar to the center pin crimp connectors for coax.
In this case there is no specific clue that is being missing in the documentation listed by Pomona.
There are a (unfortunate) amount of items that exist where the manufacturer’s don’t list a specific tool or really indicate the “type” tool.
The “bare-terminal style crimper” only defines 1 aspect of the tool.
Pomona indicates here that the tool should not be specifically designed to be able to crimp items with insulation over the crimping interface.
As for this specific tool I am not 100% sure on how well it will work.
So far I did not find an option that would be listed for the 0.094" stating diameter for the banana connector.
I would expect that when crimping that the size can go down a visible amount, but I cannot say that it would go all the way down to the 0.068".
As for my recommending a tool that is of the hex type that would be from seeing examples of similar looking terminations that do have enough information (if not specifically listed) to point to a tool. These are the type of contact or connector that is machined. The ones I have seen tend to have crimping tools that have the hex type or a coming from all sides type of crimping.
I decided to try crimping with the tools I have before buying a $70+ crimper that is for coax work (which I do not do a lot of) and might not be sized for this specific purpose. I used the Klein 3006CR. It made a crimp on 18ga wire on the factory crimp strength setting that worked fine with these connectors, I cannot pull it apart by hand if I wanted to.
If I ever do try it with a hex crimp tool like the Paladin PA8049 I will update the thread.
