A combination of a waterproof plug and a waterproof socket is a connector that can be used in a watery environment. Its main performance is to be able to withstand a certain external water pressure, but also to ensure the internal performance of the connector, can be used normally, in this case, the connection between power supply and electrical equipment, the use of electrical equipment can work normally.

Waterproof plug is only a general term. Generally speaking, waterproof plug can not only be waterproof, but also anti-dust, oil and other general solvents. The protection level of 3 Pin Waterproof Cable Connector is generally assessed according to the IP waterproof rating. IP followed by two digits, generally displayed as IPXX. The first rank of XX is from 0~6 and 6 to the highest level. XX's second grade is from 0 to 8, 8 is the highest grade, so the highest waterproof grade of 4 Pin Waterproof Cable Connector is IP68.

Waterproof plugs and waterproof sockets are used in many places. In industry, it can be used in LED lighting, outdoor lighting facilities, lighthouses, cruise ships, sprinklers, and so on. There are also some detection equipment, communication equipment, etc. 3 Pin Waterproof Cable Connector will be used whenever possible to touch water. In other application fields, such as military field, there will be stricter requirements relative to industry, generally used in submarines, submarine-launched missiles and other places.

So how to define the protection level of waterproof plugs and sockets has already been a specific standard in the industry. I believe that many people just know that IP68 waterproof plug is the highest level, and do not know how each waterproof level is divided. Now let's learn about the specific classification of 4 Pin Waterproof Cable Connector.

We use IP code to indicate the standard of connector waterproof level.

The two numbers behind the IP code represent the difference between "dustproof" and "waterproof" respectively. Dust-proof objects refer to solid objects, such as dust, fine wires, smaller tools, etc., and water-proof objects refer to liquids.

Following is a detailed description of the level of IP division, we use IPXx to express (IP followed by capital X for dust, lowercase x for waterproof).

Protection level -X, protection level for solids:

When X=0, there is no protection.
When X = 1, it can prevent large parts of the human body (such as fists, palms, etc.) from entering or solid objects larger than 50 mm in diameter from intruding.
When X=2, it can prevent 12.5mm from invasion of solid matter, it is equivalent to the length of one finger.
When X = 3, it can prevent the entry of common small tools and ordinary wires, which is equivalent to the object with a diameter of more than 2.5 mm.
When X=4, a solid substance with a diameter larger than 1mm can be prevented from entering, equivalent to a wire stripped away from the wire.
When X = 5, prevent dust deposit fully into the equipment to affect the normal operation of the connector, thereby causing damage to the 3 Pin Waterproof Cable Connector.
When X=6, solids can not enter.

Protection level -x, liquid protection level (including drip, spray, immersion and other forms):
When x=0, there is no protection for water.
When x=1 prevents water droplets from entering.
When x=2, when the connector housing tilts to a 15 degree angle, the droplet drips into the housing without affecting it.
When x=3, rain and so on, from 60 degrees to the corner of the shell or water spray, the connector will not be affected.
When x=4, the liquid splashes onto the connector housing at any angle in any direction.
When x=5, rinse with water without any harm.
When x=6 can prevent strong jet water (such as seawater) entering, it can be used in the cabin environment.
When x=7, it can be used to prevent water entry during short-term immersion.
When x = 8, continuous water immersion under certain pressure can prevent water from entering the 4 Pin Waterproof Cable Connector during complete and continuous submergence.
