What are IP protection classes?
The first digit can have values from 0 to 6 and describes how well the device is protected against the ingress of solids. The second digit can have values from 0 to 9 and indicates how well the device is protected against the ingress of moisture. The higher the number, the better the protection.
For example, a device with protection class IP68 has the best protection against the ingress of dust and is very well protected against ingress of water. A device with protection class IP44 has sufficient protection against the ingress of foreign bodies and is protected against splashing water.
