This is not a SFW instance. NSFW communities will be tagged, and efforts will be made to keep SFW communities clean, but proceed at your own comfort level.
Very clean. All the touchscreens are IP67 or better and can be wiped, washed, and sanitized very easily and repeatedly with minimal training. Ours are even pressure washed alongside the rest of the equipment during routine cleaning and maintenance.
Keyboards are more difficult to keep clean, have plastic bits that don’t show up on a safety metal detector on the line, and just in general aren’t needed when the only functions the operator really needs are start and stop.
Pretty common for HMIs in a factory, in my experience. Keyboards are dirty and difficult to keep clean.
How clean are the touchscreens on a scale of “factory new” to “toddler grime”?
