John, Does Steve have an e-mail address or do we respond thru yourself? It would seem that some improvement on the quality or type of enclosure would be in order. I would presume the electronic assembly is conformally coated, if not this would certainly help but, connectors don't get coated nor other devices such as trimmers presets etc.. Certainly wood shavings/dust are very aggressive material and will become more so if there is high humidity or condensation present. It would be interesting to know how the PM recommends the cleaning be done especially in a saw mill. This suggests a new line for the Monty Python lumberjack sketch...

While I can provide some real life experiences for this gentleman, I thought that this group could provide some more concrete information. Thanks John Parsons Circuit Graphics Ltd. Hi! I am curious about corrosion and gold plated connectors. I work in a sawmill - dusty enviroment. There are PM's which call for unplugging boards and cleaning these connectors, once a year. My experience is Gold doesn't corrode. Leave the boards for a longer time. Unplugging these boards, in my opinion, would create more of a problem then cleaning would prevent. (unplugging/plugging - starts to scrape off the Gold plating. What do you suggest.
