Default Source for solid conductor RJ12 cables? (Chinese DRO scale cable)

Does anyone know where I can buy RJ12 telephone cables with solid wire?

I soldered the scarce chinese scale cables to the scale electronics.
Unfortunately, I did not add an external clamp for the cable next to the
electronics, and my display unit is displaying garbage.

From past experience, it's too darned expensive to buy the chinese DRO
cables by themselves. Worse, the conductors are the next to impossible to
solder stranded wire.

My quick solder job was to simply unfold the flattened conductors from the
small (RJ11?) end, and solder them to the PCB traces. This probably would
have been good enough, except there's no support for the connector
block... Enough flexing, and things get odd.




An RJ-12 is the same physical size as an RJ-11 telephone base cord plug, but
has 6 pins instead of 4.

If that is what you are talking about...

On the rare occasions when I need them I buy 6 pin RJ-12 plugs made for
stranded wire and crimp them onto 6 conductor stranded satin wire base cord
with an appropriate crimper. This will be a hundred times more durable in
any machine with movement or vibration than a solid wire version. I
probably have a box on the shelf in the shop and a partial roll of wire with
a few hundred feet left.

If you really want solid wire, then just buy some solid wire. Telco (22 or
24 gage multi-conductor with twisted pairs) is available from 4 conductor
upto several hundred pairs. Note that you CAN NOT use the same RJ plug on
solid wire as you use on stranded wire. Solid wire plugs skin the
insulation off and pinch the wire when crimping. Stranded wire plugs pierce
the wire.

Flexing kills solid wire.
