DF13C connectors...we are using tin version ? -really?

Can anyone confirm i see tin DF13 connectors on my Pixhawk ? - both male and female look like tin, at least it does not even look close to a sub-standard 0.4um gold plating.

The reason I ask, is that I usually apply conformal coating to everything I use professionally (and for fun too).
I live near sea, in Norway , corrosion from salt in air, and shifting temperatures (especially when taking eqipment in/out during winter), is an extra challenge. So I have high standards when it comes to these things.

Replacing the DF13’s is an option, SMT is simple enough to work with, but then, do stick to best practice, I’d need to source or crimp my own cables as well, and all that would cost lots of time.

Is there a imporved Pixhawk planned ? - switching all DF13’s and crimped connectors to gold plated version would cost about $4 per Pixhawk.

BTW: ADC 3v3 input is also tin, this too is not best practice, the DF13 have an expected life of 30connections, and a high-resolution ADC, at such low voltage, is very prone to getting extra noise from tin-connectors.

I hope I am wrong, and it’s some other kind of alloy than tin. :slight_smile:

And before somebody says: "tin is ok for most people that fly in good weather"
Tin version is rated as good for 30 dis/reconnects - gold for 50, by manufacturer. - so everybody would be happy for this being fixed.

The most reliable connector is…no connector.
For maximum reliability (and minimum convenience), just solder wires onto the board. There won’t be any stress relief, so gluing the wires to the board or clamping them to something will be necessary.
You won’t get even 30 connect/disconnect cycles of course. The solder pads on the board should be good for 5 or so reheats if you’re careful.
