Can IP68 be used in rain?

The Ingress Protection (IP) rating is a standard measurement that defines the level of protection an electronic device has against various solid objects and liquids. The IP rating consists of two digits, with the first digit indicating the level of protection against solids and the second digit indicating the level of protection against liquids. An IP68 rating indicates that the device is dust tight and can be submerged in water up to a certain depth. But can IP68 devices be used in heavy rain? Let's explore this question in detail.

Understanding the IP68 rating

The IP68 rating is one of the highest levels of protection for electronic devices. It means that the device is completely dust tight - no dust particles can enter the device and cause damage or malfunction. Additionally, it signifies that the device can be submerged in water beyond 1 meter depth for a prolonged period without any harmful effects. However, it is important to note that the IP68 rating does not guarantee protection against heavy rain or continuous exposure to water.

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. Heavy rain often involves higher water pressure than simply being submerged. This increased pressure could potentially breach the seals of the device, allowing water to enter and cause damage. Additionally, prolonged exposure to water can also lead to corrosion and other long-term issues, even if the device initially had an IP68 rating.

Additional protective measures

To ensure optimal protection of electronic devices in heavy rain, additional protective measures are recommended. For example, using waterproof casings or covers specifically designed for outdoor use can provide an extra layer of protection. Additionally, it is advisable to avoid unnecessary exposure to heavy rain or submerging IP68 rated devices for extended periods. Regular maintenance and inspections are also crucial to check for any signs of damage or wear that may compromise the original IP68 rating.
