Is IP67 better than IP65?

When it comes to choosing electronic devices or equipment, the level of protection against dust and water is an important consideration. In this article, we will explore the difference between IP67 and IP65 ratings, discussing their features, applications, and determining which one is better suited for various environments.

IP67: Complete Dust and Water Protection

An IP67 rating indicates complete protection against ingress of dust and immersion in water up to 1 meter depth for 30 minutes. The first digit, "6", signifies that the device is completely dust-tight, preventing any solid particle from entering the enclosure. The second digit, "7", indicates its ability to withstand temporary submersion in water without causing damage to the internal components.

Due to its superior sealing capabilities, IP67-rated devices are commonly used in rugged outdoor environments such as construction sites, marine activities, and military applications. They can withstand extreme weather conditions, heavy rainfall, and exposure to fine particles without compromising functionality.

IP65: Limited Dust and Water Protection

On the other hand, an IP65 rating provides limited protection against dust and water. The first digit, "6", remains the same, indicating complete dust resistance. However, the second digit, "5", means that the device can only handle low-pressure water jets from all directions, but cannot be submerged.

IP65-rated devices are suitable for less demanding environments where direct exposure to dust and water is limited but not completely eliminated. Examples include indoor industrial settings, laboratories, and medical facilities where occasional cleaning with water or exposure to splashes may occur.

Which one is better?

The choice between IP67 and IP65 depends on the specific requirements of your application. If your device needs to withstand excessive dust, heavy rainfall, or temporary immersion in water, then IP67 is the preferred option. On the other hand, if your device will be exposed to occasional splashes or low-pressure water jets, IP65 provides sufficient protection.

It's important to note that even though IP67 offers a higher level of protection, it doesn't necessarily mean that IP65-rated devices are inferior. The key is to match the IP rating with the environmental conditions your device will encounter.


In summary, IP67 and IP65 ratings define the level of protection against dust and water for electronic devices. While IP67 provides complete dust and water resistance, IP65 offers limited protection withstanding low-pressure water jets. Choose the appropriate rating based on the specific environment and requirements of your application to ensure optimal performance and longevity of your electronic equipment.
