IP69K Explained: Washdown Ratings for Computers and Monitors
IP69K is the highest ingress-protection rating for dust and water, certifying a device against high-pressure, high-temperature washdown. It is the rating to look for when a computer or monitor must survive sanitising jets in food, beverage, and pharmaceutical plants.
What the IP code means
An IP rating has two digits: the first (0 to 6) is protection against solids and dust, the second (0 to 9K) is protection against water. IP69K certifies complete dust-tightness plus resistance to close-range, high-pressure, high-temperature water jets — the conditions of an industrial washdown.
IP69K vs IP66 and IP67
IP66 resists powerful water jets and IP67 resists temporary immersion, but neither is tested for the roughly 80°C, 1,450 psi jets used in sanitation. IP69K is. For washdown environments, IP69K on a fully sealed stainless-steel enclosure is the safe specification.
Where you need it
IP69K stainless computers and monitors are used in meat and dairy processing, beverage bottling, pharmaceutical manufacturing, and commercial kitchens — anywhere equipment is cleaned with pressurised, heated, chemical washdown. NEMA 4X is the equivalent North American enclosure rating and is often specified alongside.
Frequently asked questions
What is IP69K?
The highest IP rating — dust-tight and resistant to high-pressure, high-temperature washdown water jets.
Is IP69K better than IP67?
For washdown, yes. IP67 covers immersion but not high-pressure hot jets; IP69K is tested for both.
Is an IP69K computer food-safe?
IP69K stainless enclosures are designed for hygienic washdown environments; confirm the enclosure is 304 or 316 stainless steel.
