How about something as high tech as vaseline.  We fill all our terminal
blocks with it.  By the way, the environment all our electronics are used in
hangs off the side of tank trucks, is constantly exposed to moisture, salt
spray, petroleum products and heavy truck mechanic type 'electronics
technicians'.  All electronics gets potted, all butt splices get filled with
RTV before getting crimped and all terminal blocks get vaselined before
leaving the factory.  Not surprizing, 99% of all tech calls are on
competitors systems and 98% of those calls are for poor connections.

Subject: [EE]: Protection against salt corrosion


Has anyone recommendations for a coating for a plug &
socket exposed to marine air and the odd splash that will
prevent corrosion ? I'm replacing an existing DIN p&s that's
been quite badly eaten away over just a couple of years and
would like this one to last a little longer. I already have heat
shrink tubing and silicone to seal the cable entry points and
solder joints but of course these can't be used on the actual
contacts. Maybe something like CRC / WD40 but how long
does that last ?

TIA
