Test lead connectors for vibrating machinery installation ?

[Kiriakos GR]

Indeed this is an unusual topic and or low popularity topic. 

Industrial sites are often a great test bed this stressing beyond measure electronic systems along cabling.
In many cases it is required to be a master control panel / inspection room, that many wires will arrive to it from stable and or vibrating machinery.

Usual question between installers electricians, what would be best electrical connectors that will maintain stable connection even at vibrating machinery?

The recommendation unfortunately differentiates according to electrical application.
Voltage monitoring ?
Current monitoring ?
Temperature monitoring ?

In theory, first thought this is a 4mm banana plug.
But if this idea its not working,  then my best advice this is of you to think of waterproof connectors.
waterproof connector systems these offer not only waterproofing, but additional protection even against vibrations.

Next question to follow is how many wires per connector?
There is no single answer here, we might need a pair as minimum or much more.

Next question to follow this is of what material the connector will be made of?
Any machinery this vibrating or not, this will be at specific environment and here the surrounding temperature of that space it also becomes a factor.

Most ancient solution of connectors these designed to tolerate vibrations this is no other than BNC locking connector, in the most simple form.
Armored tank car this is also an vibrating machinery, this is THE first application that forced industry so to develop a special class of connectors (high reliability ones).   
Industry of Aviation this also need a special class of connectors, these ones they should withstand vibrations along significantly greater range of temperature.

In conclusion: Vibrating machinery this is a common challenge at industry production, and army type vehicles and also at Aviation / Aerospace.
Do not expect to find a solution at the range of cost effective solutions other than the waterproof range of electrical connectors.
