Identify Wire

Guest
I've got lots of single conductor stranded reels of wire to identify. How do I tell if it's 0.1 or 0.2mm strands? My calipers aren't accurate enough.

All I can think so far is to snip a bit and optically compare.

measure resistance of know length?

Microscope with reticle, or comparator (little hand-held lens-with-scale gizmos).
Or, look up the part number on the reel. There usually is one (and your
goods-receiving folk should write a label if there isn't).

Or measure fusing current. Or weigh a know length.

This is to identify unlabelled cables. Goods in could write one, but with the data coming only from their imagination it would not be helpful.

I'll try that, and see if the length required for adequate accuracy is not excessive. It might be.

0.2mm is 0.00787" What caliper can't measure 7 thousandths?

Wind it on a pencil? 13 turns (12.6 turn) per 0.1 inch. (0.2mm)

0.1mm is .00393"

I like that idea. Whether it can be done gaplessly enough I'm not sure, but can find out.

I suspect buying a better micrometer may be the solution.

Buy a micrometer ??

Strand gauge is usually not needed . Overall gauge is and strand
count, and you could easily derive the strand gauge with that knowledge.

Harbor freight $20

Home Depot maybe $25

Us and metric all in one, and no need for calibration if labeled "for
reference only". Still complies with ISO standards at that point.

assuming micrometer calipers is something you don't have:

Wind 20 turns on a needle (or similar tool) and measure with a ruler.
(or ordinary measuring calipers if you got 'em)

for more precision you could stick the 20 turn winding and ruler on a scanner...

Even the $10 (on sale) dial calipers from Harbor freight will do that.

Get even more use out of the cheap ones.
The harbor freight dial calipers are cheap enough to
use to scribe lines to mark cutting or folding lines.
They'll be on sale again for the next set.
Although, I'm disappointed they don't put the
dial calipers on sale now, only the electronic ones.
Why mess with a battery when the dial works fine.

Yup, looks like time to upgrade from vernier to dial.

Ha, you paid to much even though I did pay that for one from HF
however, I also got a one form Aldie's and they were clearing them out,
I think I paid like 5 bucks for them, digital dial works just as good
as the HF.

If you don't use this stuff everday they're great..

Dial calipers don't have dead batteries every time you want to use the
tool.
