A good bit of thought goes into selecting the correct computer enclosure for a harsh manufacturing floor.
When looking for an enclosure that will withstand a wet, dirty, humid or wash down environment, have you considered how the cables will enter and exit the cabinet? Do not allow cable penetrations to be a weak link in the enclosure solution. If running conduit is not an option for cable entry, the next best solution is using a sealed gland that meets NEMA 12, NEMA 4, and NEMA 4X standards.
