Is there any merit in connectors like this?
P.S. How are you going to clean the female connector with corrosive deoxit and expect the connection to remain consistent?
I was going by pp.128 of the Keysight 34420a manual.
Here, Keysight suggests putting a drop of Deoxit in the contacts of the Lemo connector.
Those contacts are copper.
They don't say remove it afterwards. In fact they end with 'Engage and disengage several times to distribute...'
They also don't specify which Deoxit product to use which is a whopping drawback.
Perhaps they mean the 'shield' version?
If you don't like Deoxit (whichever one it turns out to be) there is always Santovac 5. Very viscous and about as inert as anything.
Sadly I cleaned my diffusion pump and haven't filled it again.
Santovac 5 won't remove oxidation but it will probably prevent it if applied to new parts which is really what we are talking about here.
To test, I can either restore my HP 419A or use my HP 3456A. Neither may be ideal but they are on hand.
Tentative test plan:
1) Measure resistance of a loop using some of said parts once lubricated. Perhaps 5 mated pairs.
2) Measure Seebeck of said loop after, I don't know, heating up one side of the connector with a hot air pencil or heating up one connector with a hot air gun and then immediately mating them.
3) Put parts on shelf
4) Repeat after a month.
Constructive criticism of test plan welcomed.
