Which IP rating is best for waterproofing?

When it comes to choosing the right level of waterproofing for electronic devices, understanding their Ingress Protection (IP) rating is crucial. The IP rating system classifies and rates the degree of protection provided against the intrusion of foreign objects like dust and water. In this article, we will explore three common IP ratings that are widely used for waterproofing electronic devices and discuss their suitability for different scenarios.

IP65: Dust-tight and Protected against Water Jets

The IP65 rating indicates that a device is completely dust-tight and protected against low-pressure water jets from any direction. This rating is suitable for devices that are likely to encounter dusty environments or occasional exposure to splashes of water. Such devices can be found in outdoor settings where weather conditions can vary, such as security cameras or handheld GPS devices. However, it is important to note that IP65 does not guarantee protection against submersion in water, so caution must still be exercised.

IP67: Dust-tight and Protected against Immersion in Water

Devices with an IP67 rating are not only dust-tight but also protected against immersion in water up to a certain depth and duration specified by the manufacturer. This rating offers a higher level of protection compared to IP65, making it suitable for devices that may come into contact with water for an extended period or be submerged briefly. Smartphones and fitness trackers often carry an IP67 rating, allowing users to confidently use these devices during activities like swimming or in wet environments.

IP68: Dust-tight and Protected against Continuous Submersion

For the most demanding waterproofing requirements, the IP68 rating provides the highest level of protection. Devices with this rating are completely dust-tight and can withstand continuous submersion in water under conditions specified by the manufacturer. This makes IP68 suitable for devices used in underwater photography, scuba diving, or industrial applications where prolonged exposure to water is expected. However, it's important to understand that the depth and duration of submersion may vary between manufacturers, so checking the device's specifications is essential.

In conclusion, the choice of IP rating depends on the specific needs and usage scenarios of an electronic device. While IP65 offers basic protection against dust and water jets, IP67 provides additional protection against immersion, and IP68 is designed for continuous submersion. Before making a purchase decision, it is important to carefully assess the device's intended use and consult the manufacturer's specifications. Ultimately, choosing the right IP rating will help ensure the longevity and functionality of your electronic device in various challenging environments.
