What is IPX1 in ingress protection ?

IPX1 ingress protection is a measure used to determine the level of protection provided by enclosures against water ingress. It specifically refers to the resistance of an enclosure to vertically dripping water. The IPX1 rating ensures that the device is protected against water drops falling vertically onto it from above, but it does not indicate protection against any other type of water exposure.

The IP rating system provides a standardized measure of protection levels provided by electrical enclosures against solids and liquids. The IP code consists of two digits, with each digit signifying a specific degree of protection. The first digit ranges from 0 to 6 and represents the protection against solids, while the second digit ranges from 0 to 9 and indicates the level of protection against liquids.

The testing process for solid ingress protection involves filling the enclosure with a solid substance, such as sand or saltwater, and then allowing a specified amount of time for the substance to seep into the device. The amount of time allowed for the substance to seep into the device is usually expressed in minutes.

The second digit, which ranges from 0 to 9, indicates the level of protection against liquids. In this testing, a substance with a IP rating of 1 would allow the substance to seep into the device for a maximum of 1 minute, while a substance with a IP rating of 9 would allow the substance to seep into the device for a maximum of 9 minutes.
