IP69 at the front and stainless-steel housing with a blue FDA-compliant gasket suit washdown areas, while splinter-protected front glass adds impact resistance.

Selection Notes

The IP69 front rating and stainless-steel housing with blue FDA-compliant gasket meet DIN EN 1672-2 and FDA 21 CFR 177.2006, so this panel tolerates direct washdown and caustic cleaning cycles rather than just splash protection. IP20 at the rear means the cutout still needs a sealed enclosure on the non-wetted side. At 12.1 inches it sits between the 10.1-inch and 15.6-inch hygienic panels in the same family, a middle ground for stations that need more screen area than a compact unit but do not need a full overview display.

Applications

The IP69 and FDA-compliant construction target food, beverage, and pharmaceutical lines that need washdown cleaning between batches. The PROFINET interface and WinCC Unified Comfort V17+ configuration integrate the panel into existing SIMATIC PLC networks for machine-level operator control.
