Looking for logic analyzer connectors

[Nico Coesel]

I noticed the more professional logic analyzers have these nice spring
loaded connectors that can be pushed onto a wire or a header pin
without wearing out (much). Anyone knows where to buy these without
filling the pockets of Tek or Agilent?

Hi Nico,

There are a couple of different varieties. One type has a "J"
hook (retractable) while the other is more like a pair of
"<" and ">" (i.e., grabs from both sides instead of just
one side).

The micrograbbers ("J") can be found (in various qualities)
for as little as $1 ea. Of course, if you need 160 of them
(plus returns) it gets a bit pricey, regardless. :<

Often, its more economical to pick up an old analyzer
"surplus", discard the electronics and just save the
cables! :-/

Actually I'm not looking for the grabbers but for the connectors with
which you usually connect the grabber to the probe. I want to make
some flying leads sets.

This Ebay item looks very much like what I want to make:

Grab a bag or two of Molex P/N 16-02-0102 or one of its siblings (search
term on Digikey "C-Grid" for other platings and wire sizes) and crimp up
your own. Cover with a piece of shrink tube and you're there. These fit
great on standard 0.025 posts without needing any other housing.

I have those now but they wear out very quickly.

Interesting. I have a bag with dozens of leads of various lengths and
colors with those connectors on either end and the only ones that aren't
snug any more were "sacrificed" intentionally by forcing them onto
DB-style pins when nothing else was readily available. I love them for
interconnects within and between dev/proto/breadboards since the shrink
sleeve eliminates (mostly) the chance of a free end making a fatal
connection.

You can buy this stuff in *rolls* -- i.e., one connector
every 3 or 4 inches, IIRC. Awful expensive way of making
jumpers of 4" multiples, though :-/
