I use something like this:I have tool not work well.
It also seems that the jaws were installed upside down. I had been holding the tool "upside down" so I could see how the wire was positioned in the connector. It's much more convenient with the jaws installed like the OP's tool.In this picture the near end is for the wire support crimp. It's characterized by a larger crimp port.
And yes, you do the entire crimp in one Feld swoop.
$68 is a bit much. I bought something similar from Jameco that would do 3 different sizes for aboutI think the kit actually costs half as much as just the tool itself which was a bit of a shock.
That's something that has never cross my mind, swapping upper and lower jaws based on the way you hold the tool. I have a standard ring terminal type crimper with plastic jacket that I'm always fussing with in order to get it into the tool properly. I'll have to look into whether I can swap the jaws around. If so - - - great suggestion. Thanks.It also seems that the jaws were installed upside down.
This makes sense as you "assume". Low voltage wiring will have a thinner insulation and with a large insulation support crimp - it can be rather loose. Having the option to back crimp the insulation support on larger or smaller insulation diameters makes sense. I think it's a safe assumption.you have to crimp twice, once for bare wire, once for insulated part of wire. Also, the PA-09 tool has different spacing/hole designations than the SN-28B, and more of them. That lets one adjust the crimp based on insulation and wire thickness, I assume...
The SN-28B I posted works fine for Dupont connectors. That's what I bought it for. It also works for some other connectors I happened to have.I've been using the 28Bs and not particularly pleased with them.
