The currently manufactured waterproof electrical connectors has two identification feature numbers. What is known is the strength of the protection. First, starting from the first digital identification, the number from 0 to 6.0 indicates no protection, not to mention here. The degree of protection of 1 prevents objects larger than 50 mm from entering. The degree of protection of 2 prevents objects larger than 12 mm from entering. The degree of protection of 3 prevents objects larger than 2.5 mm from entering. The degree of protection of 4 prevents objects larger than 1 mm from entering. The degree of protection of 5 prevents the incoming dust from affecting the appliance. The degree of protection of 6 is completely protected against dust ingress. The second indicator feature number is from 0 to 8, starting with 0 and there is no protection function.
The degree of protection of 1 prevents water droplets dripping from the vertical direction from affecting the appliance. The degree of protection of 2 prevents immersion of water droplets inclined at 15 degrees. The degree of protection of 3 prevents damage from intrusion of water sprayed from vertical <60 directions. The degree of protection of 4 prevents splashing water from entering. The degree of protection of 5 prevents the sprayed water from immersing in the appliance. The degree of protection of 6 prevents the infiltration of large waves of water. The degree of protection of 7 prevents the performance of the appliance from being affected when immersed in water. The degree of protection of 8 can completely sink the connector in the water and the appliance is not affected. Waterproof connectors used in various industries have different protection properties and can be purchased as needed.
