IP69K means the connector is fully dust-tight and withstands high-pressure and high-temperature water jet cleaning (per ISO 20653, approx. 80 °C, 80–100 bar).
Yes, they are protected against water at high pressure and temperature. However, this test does not automatically cover immersion – for immersion, IP68 is often specified in addition (e.g. IP68/IP69K).
IP68 is designed for continuous immersion, IP69K for high-pressure and hot-water cleaning. These are different tests, not an ascending scale – which is why connectors for both often carry the combined rating IP68/IP69K.
In food and beverage production, the pharmaceutical industry and installations with intensive cleaning processes and high hygiene requirements.
Yes, they are specifically designed for high-pressure and hot-water cleaning and maintain their sealing throughout.
