Some industrial environments—chemical processing, paper making, etc.—are known to be hostile to electrical connectors. Food and beverage environments are just as much of a challenge to good connector design and construction as their extreme industrial counterparts.
But in the food industry, good design has to go a step further. It should be a fully inclusive solution that encompasses the electrical safety requirements including UL and CSA, the NSF food equipment requirements, the IEC extreme sealing requirements, and the trusted materials identified by the FDA.
