Hi - I'm working on setting up our lab with cabling. One thing I keep on buying and that we keep on needing more of is banana-banana cables. The cheapest source I've found so far is here: http://dkc3.digikey.com/PDF/US20... (figure 5) at about $5 each. This pricing is OK - but the cables are PVC which makes me sad. I'd really prefer to see silicone jackets.

Any suggestions? Or are these Pomona jobbies going to be the best that I can do?

Thanks!

Do you really want banana plugs? Is it for a school lab?

I agree that they are fairly robust. How many items of lab equipment use banana sockets? Or will you end up in BNC plugs, Molex headers, or fiddly little surface mount connections?

The robust banana leads will probably outlast and destroy anything delicate that they connect to.

David.

I use bananas on most of my test boards. Primarily for power connections, but also some signal stuff. I like them because they're simple and easy to use.

It is a lab for a company that focuses mostly on R&D.

Here (in Germany) standard banana cables are
forbidden in labs in schools and universities,
because you could put one into the wall plug and
touch the other with your hand. So we had to
equip all equipment with safety-plugs
:twisted:

das ist forboden!

Yea I have no really helpful advice, buying just the jacks from digikey and using your own cable in between might give you more options (length, jacket), but doesn't really save much money at all since the jacks are still about 1 dollar a piece.

First, when looking for something like that (especially when I don't need it tomorrow) I troll on eBay for a while. Step motors is a case where I got a wide selection at a small fraction of real pricing. E.g., red/black set for ~$5:

Get'em right from Hong Kong:

Jameco is decent for that stuff. In this case they carry "the" Pomona brand and are indeed ~$5/cable.

But also visit the surplus electronics sites:

http://www.bgmicro.com/
http://www.goldmine-elec.com/

Note that you can get the "plug" ends for $1 or less, and then use whatever wire color/length that you like. (Pomona's are 18ga.)

I've never met a pig I didn't like, as long as you have some salt and pepper.
