Using no gold plated contacts instead of original gold plated contacts

(1/2) > >>

Marbek_Elektronik:
Hi,
I have ordered Deutsch gold plated female contacts for Danfoss Controllers.
But I get non plated contacts.

What do you think: Is this a risk to use without gold plated contacts?
I think yes. If there are very low currents and after a few years it might be a problem.

Has anyone experience with this? What says danfoss?

SJ Industries:
I use gold plated when ever I can, that said after many years of breakdowns on mine sites i can say that 90% of electrical dramas will be the wire itself not the contact between pins. Non tinned wire is terrible. Assembly is key, people not putting the blanking plugs in is a killer. also corrosion x sold by snapon over here is the awesome, a little squirt of that keeps moisture out and the seals in good cond. I dont rate dialectric grease.

So after all that, if your wire is good quality then non plated pins when nothing else is available should be fine.

FluidPowerTom:
I've made extensive usage of the non-gold contacts without issue.  The only time that I've insisted on the gold contacts is for a very, very long CAN bus.

oiltronic:
Same as SJ & Tom.  Oldest machine still in service has been open to the damp weather for over 8 years without a single pin-corrosion problem.  Sealing plugs and tinned wire are much more important, in my opinion.

Nilla:
Hi guys!

We would recommend gold plated contacts.

The main reason is for our input pins. The inputs have a high resistance and that makes for a low wetting current, so any corrosion/oxidation could cause issues over time.
