Hello all,

for quite some time, I am experimenting with Low EMF connections/cables. I have different things allready tested and found this crimp spade lugs from AMP (see picture) to be very good. Unfortunately I cannot find it on-line. Does anyone know the partnumber of it or a place where I can find it?

thx
quarks

Sorry, can't help you with that particular part, but I see that Mouser carries Pomona low EMF lugs with banana plug inserts:

Thx a lot grenert,
I know the Pomona low emf parts and it is good to know where to get them outside of the USA.
For my actual DIY low emf experiments I look especially for crimp spade lugs pure copper (pref. Gold plated and/or with tellur) with low thermal mass (for fast equilibrium; I hope that is the right word).
All the parts I found and tried are either heavy Audio versions or tinned copper versions.
The above showed AMP is so far the best match to what I want.

Is there anyone else, interested in this topic?
If yes, I will keep on asking and posting. 

So far I found this article very good "Metrology 101 - Watch out for those Thermoelectric Voltages!" (see link)

If anyone has more useful ideas, how to do more tests, please share.

With grenerts good hint, I ordered at mouser some Pomona Low EMF stuff.
I made already quite a few comparisons and will keep on testing.

PS: Still hope to get a hint for the AMP spade lug or something similar!
