Do they sell a gauge to measure Coaxial Power Connectors?

AKA "barrel connectors".

I can get close using a ruler on the outer part of the plug, but those
pins inside are near impossible to measure.

There are so many variations of them too.

Someone must have some sort of gauge to measure them....


I don't know how you'd measure after it went through a crimp-tool.


** Huh ??

When you hook a coax connector to coax cable, you crimp it with a crimping device so it won't fall off of the coax cable.
(at least I did)

As with every connector, if you crimp it at one end, its inevitably going to change measurement at the other end (though probably not significantly).

I think youall are mixing coax power connectors that are used on many
wall cubes to power the electronic devices and the coax connectors like
used on the antenna cable called coax, such as RG-8, RG-6.

The mating areas of the coax power connector are not crimped or any
other thing to change the mating dementions.

You're thinking of RF coaxial connectors.
Aside from the fact the don't change at the mating side of the
connector.

Almost coaxial power connectors have solder terminals on the wire side
and they don't change shape either at the connection/interface side.

The center terminal may drift in position if you overheat the connect
during assembly/soldering.

Oh. I guess we learn something new every day?

One more idea.
Buy or make a tapered hole gauge:
<https://www.google.com/search?q=taper+hole+gauge&tbm=isch>
It would need to be made for the purpose to prevent bottoming out on
the connector. I have a few that I made for go/no-go inspection
gauges by grinding a steel rule blank and etching marks with ferric
chloride.

Are you sure that your Mitutoyo calipers are not a counterfeit?

I gambled and bought a Mitutoyo Digimatic 500-196-20 for $35. It was
a fake. After cleaning out the shavings from the guts, removing the
burrs, and squaring the jaws so that they were parallel, I did
something that blew up the electronics. Sorry, no photos.

Well, I bought them some years back from an actual Mitu distributor, so
I'm pretty sure they're real. No swarf, no detectable parallellism
error, no noticeable offset between depth gauge and ID/OD blades, good
battery life, nice case.

My cheap 'n' cheerful Chinese ones are actually quite OK as well.
