Re: pins, cables

In the US, pins and sockets are generally described as having mating
diameters equivalent to AWG sizes. That is pins (male contacts) and
sockets (female contacts) of like gauges will mate properly.
Pins and sockets are available loose from any of the major connector
manufacturers and can be had as crimp-type or solder-type.
Crimp types are much more convenient to use and, with the proper
choice of contact and crimp tool, can produce connections superior
to those available using solder.
Another advantage to using crimp contacts is that after the contacts
have been crimped onto the wires, they're just poked into the right
locations in the connector inserts, eliminating the need to solder
at the connector.

Thanks for this synopsis.

Single wires can easily be prepared for probing a connector by
crimping on the proper sex contact on one end, and then terminating
the other end with whatever you need: banana plug, alligator clip,
mini-hook, etc.

OK. Do you know any online illustrations of this technique?

It's a good idea to use a little shrink tubing over the crimped area
of the contact in order to give the wire a little strain relief.

Makes sense.

I suggest you go to Digi-Key's site, find loose pins and crimp tools
from various manufacturers and then go to their sites for a more
detailed view of what's out there. (What's out there is HUGE!)

Thanks, I took a look. It will take some getting used to.

You're in for a surprise when you find what good crimp tools cost!

Radio Shack sells a crimping tool for about $39. Will it do the job?
