IP68 is a standard used to classify the degree of protection provided by enclosures for electronic devices against the ingress of solid objects (like dust) and liquids (like water). The “IP” stands for “Ingress Protection,” and the two digits following it indicate the level of protection.
Here’s what each digit in IP68 means:
First Digit (6): This digit indicates the level of protection against solid objects, such as dust. A rating of “6” means that the device is completely dust-tight. No dust can enter the device, providing the highest level of protection against solid particles.
Second Digit (8): This digit represents the level of protection against water ingress. A rating of “8” means that the device is protected against continuous immersion in water under conditions specified by the manufacturer. Generally, this means the device can withstand being submerged in water beyond 1 meter (up to a maximum of around 3 meters, depending on the device) for a certain duration without suffering damage.
In practical terms, a device rated IP68 is considered highly resilient to both dust and water, making it suitable for use in challenging environments such as outdoor settings, near water, or in dusty conditions. It’s important to note that while IP68 indicates strong protection, it does not mean that the device is entirely waterproof or impervious to all conditions; users should still follow manufacturer guidelines for proper use and care.
