Default Do they sell a gauge to measure Coaxial Power Connectors?

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....

None that I've found. The parts that are hard to measure, I generally just
give up and buy a few score of each nearby size. At a PPOE,
we kept notes on 'hits' when an important failure-prone connector matched
something we could order (didn't happen a lot).

If it were time-critical (and I couldn't find a junker adapter to clip a
pigtail from), I've got drill bit shanks down to #60 (~1mm), and modeling
clay, and a measuring microscope. The thing is, even if I DID measure
accurately, the 'nominal' sizes of commercially available mates would
still be a mystery. So, it's easier to keep a divider-box of a dozen sizes
of the males/females, with annotation as to what to reorder.

but are very inaccurate when measuring small diameter internal holes such as barrel connectors. Try it & you'll see why.

Those are nice.
In addition to the standard vernier calipers, I have the dial type.
So much easier to read.
They are also available now with LCD displays.

** For accuracy, I use small & PCB drills as feeler gauges.

Which had been posted here already....

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

I've always called them "DC plugs" so folk know what I am talking about.

Sorry to hear you can't tell the difference between crap tools
and ones that work.
Or that you can't even get good tools to work.


sorry to hear you like to be childish

Sort of. I either use one of a set of matching sockets or small
lengths of fine tubing. Sockets are easier to measure using
fine twist drills which are typically sold in sets...

Sharp calipers are okay for both.

I have a couple of Mitutoyo ones that work great and weren't expensive.
Chinese ones are good for scribing circles on copper or aluminum and
other such jobs that might hurt the good Japanese ones.

My vernier calipers are Mitutoyo.
My Dial calipers are Starret.

I have a couple of the absolutey cheap plastic ones.
Those are for telling the difference between English and Metric
hardware in the "oh boy" bucket.

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).

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?
https://www.youtube.com/results?search_query=mitutoyo+caliper+fake
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.
