Can IP67 be left in rain ?

The Importance of IP67 Ratings in Rainy Environments

When it comes to electronic devices, protection against moisture and water is crucial for their long-term functionality. The IP rating system is a two-digit system that evaluates the device's resistance to solid objects, such as dust, and its ability to withstand immersion in water. The most common IP rating is IP68, which represents the device's resistance to dust and water.

While an IP68 rating is an excellent protective measure, it is not a guarantee that the device will withstand heavy rain or continuous exposure to water. In fact, heavy rain can pose a significant challenge to even the most IP68-rated devices.

Understanding the IP68 rating

The IP rating system consists of two digits. The first digit represents the device's resistance to solid objects, while the second digit indicates the device's resistance to water. An IP68 rating means that the device is protected against dust (level 6) and can withstand immersion in water beyond 1 meter (8). This means that the device can withstand contact with water, but it does not guarantee protection against heavy rain or continuous exposure to water.

It's important to note that the IP68 rating does not guarantee protection against all types of moisture, including heavy rain. Additionally, the IP68 rating only applies to the device's resistance to water, not to the quality of the water or the duration of exposure.

Understanding the limitations of IP68 in heavy rain

While an IP68-rated device can withstand being submerged in water, it may not be able to handle heavy rainfall or continuous exposure to water. Rainfall involves various factors, such as droplet size, duration, and pressure. These factors can challenge the sealing capabilities of an electronic device, even if it has a high IP rating.

In heavy rain, the increased water pressure can exert significant pressure on the device's seals and openings, potentially causing damage to sensitive internal components. Additionally, prolonged exposure to water can lead to corrosion and other long-term issues, even if the device initially had an IP68 rating.

The Importance of Additional Protective Measures

To add an extra layer of protection against heavy rain and other moisture, it's recommended to use additional protective measures, such as a waterproof casing or a shielded enclosure. These measures can help to prevent damage from heavy rain and other moisture, and also protect the device from dust and other external factors.

Conclusion

In conclusion, while an IP68 rating is an excellent protective measure for electronic devices, it is not a guarantee that the device will withstand heavy rain or continuous exposure to water. To ensure the best protection against moisture and water, it's important to consider additional protective measures, such as a waterproof casing or a shielded enclosure..
