The main evaluation criteria of the waterproof performance of waterproof connector is based on the level of IP protection. Evaluating how is the performance of waterproof connector is mainly to evaluate the last two numbers of IPXY. The first one X from 0 to 6, the highest level being 6, is to evaluate the degree of protection of preventing outer solid objects into the device housing. The second number Y from 0 to 8, the maximum level being 8, is to evaluate the degree of protection of preventing the water in various forms into the device housing. Therefore, the highest level of protection of the waterproof connector is IP68. The test of the highest level of IP68 connector, including test equipment, test conditions and test time, is decided by the two parties of supply and demand.
The level of protection of the connector used for outdoor at least needs to achieve IP67.
