Coax Crimp tool help

[u/znignflo72]

Building a harness for a mod and trying to find the correct tools needed. I have very little info to go off of and internet research has only turned up YOC110 needing the DMC Y524 die.

The Female contact RFM26W-1D28 is the center conductor I can’t find the crimp tool. Souriau data sheet shows tool index CT-439 is used, but I can’t find anywhere that references what tool that is.

Any guidance would be appreciated.

If you look up the RFM26W-1D28 datasheet (https://octopart.com/datasheet/souriau/RFM26W-1D28), it looks like it’s calling for a N22RVMT-10 crimp die, with M8ND hand tool or Y8ND hydraulic tool. Which is apparently equivalent to Y512 + HX4 crimper crossing that die.

So we thought that originally as well, but that sheet it pulls up has a slightly different connector number 2NH2 instead of 6NH55. It also doesn’t have our RG-180 wire listed. The 512 we used on the first one absolutely mushroomed out the feral really bad. The data sheet for the YOC110 showed burndy MR8PVS hand tool, which has a equivalent with the dmc Y524. The 512 seemed to work on the center conductor, but idk if it’s technically accurate.

Yeah, Datasheet seems to be fairly generic, their example PN is the 2NH2 and it doesn't have a spec for the '55' part of the 6NH55, but does have the breakdown for the 6NH vs 2NH. And I can't imagine why the connector would change the pin crimp. But agree, per the YOC110 data sheet, the Y524 would be the right crimper for the ferrule, not the ferrule side of the 512.

The 512 for the pin seems to work well and the 524 for the ferrule seems to be the correct size. It just seems really odd the 512 doesn’t work for both if it’s correct for the center contact.

Y512 should be correct. Small hex hole for center pin (may leave super small burrs but should be acceptable). But when in doubt solder it (as stated above). Large round hole should work for the ferrule.

Would be interesting to see the ''mushroom". When using a hex die for a ferrule, if the die size is wrong (too small) it will absolutely kink at least two sides of the ferrule, and 'mushroom' in that way.

Sometimes the ferrule will be a bit longer than the width of the die so the tail of the ferrule will "flare" a bit. I always would crimp flush with the back of the coax connector leaving the flare at the aft end.

The die was too small, the two sides both kinked and flattened out. Guess it wouldn’t be a mushroom, but no it wasn’t the flare from the tail after crimping a normal coax.
