Is IP69K better than IP68?

In the world of electronic devices, especially those designed for use in rugged or harsh environments, the IP rating is a crucial factor to consider. The IP rating, or Ingress Protection rating, indicates the device's level of protection against both solid objects and liquids. Two popular IP ratings for devices are IP69K and IP68. But which one is better? Let's dive into the technical details and find out.

Understanding IP69K

IP69K is the highest level of protection when it comes to the ingress of dust and water. The "6" in the IP rating signifies that the device is completely dustproof, with no particles able to enter the enclosure. The "9K" indicates that the device can withstand high-pressure, high-temperature water jets without any damage. This makes IP69K rated devices ideal for use in industries such as food processing, chemical plants, and outdoor equipment.

Exploring IP68

On the other hand, IP68 is the next best rating after IP69K. Devices with an IP68 rating are also dustproof but may not provide the same level of protection against water as IP69K. For instance, an IP68 device can withstand immersions in water up to a certain depth, usually specified by the manufacturer. This rating is commonly found in smartphones, smartwatches, and other consumer electronics that need protection from accidental spills and submersion in water.

Comparing the Differences

The main difference between IP69K and IP68 lies in their ability to handle different water pressures. While IP68 rated devices can handle being submerged in water at a certain depth, they may not be able to withstand high-pressure water jets like IP69K rated devices can. Additionally, certain chemicals present in industrial settings may also affect the water resistance of IP68 devices, making them less suitable for such environments.

On the other hand, IP69K devices provide the highest level of protection against both dust and water, ensuring complete reliability in demanding environments. These devices undergo rigorous testing to ensure they can withstand high-pressure, high-temperature water jets without any damage. However, it's essential to note that the level of protection offered by an IP rating does not guarantee absolute invulnerability; rather, it indicates the device's ability to resist ingress of solids and liquids under specific conditions.


In conclusion, whether IP69K is better than IP68 depends on the specific requirements of the device's usage scenario. If the device needs to withstand extreme conditions, such as powerful water jets or exposure to harsh chemicals, then IP69K is the superior choice due to its higher level of protection. However, for everyday consumer electronics that are primarily exposed to accidental spills or submersion, IP68 provides sufficient water resistance.
