Waterproof connectors are connectors that can be used in water-bearing environments and can ensure that the mechanical and electrical properties of the connectors can be used normally under certain water pressure.
The P (INTERNATIONAL PROTECTION) protection level system was drafted by IEC (INTERNATIONAL ELECTRO-TECHNICAL COMMISSION). Electrical appliances are graded according to their dust and moisture resistance characteristics.
The foreign objects referred to here include tools. Human palms, fingers, etc. are not allowed to touch the live parts of the electrical appliances to avoid electric shock.
The IP protection level is composed of two numbers. The first number indicates the level of dust and foreign object intrusion of the electrical appliance, and the second number indicates the degree of airtightness of the electrical appliance against moisture and water intrusion. The larger the number, the higher the protection level.
The first characteristic number (number) indicates the degree of protection
The first number indicates the protection level
0: No protection
No special protection for people or objects outside
1: Prevent solid objects >50mm from entering
Prevent the human body (palm) from accidentally touching the internal parts of the appliance; prevent foreign objects >50mm from entering
2: Prevent solid objects >12mm from entering
Prevent the human body (fingers) from accidentally touching the internal parts of the appliance; prevent foreign objects >12mm from entering
3: Prevent solid objects >2.5mm from entering
Prevent small foreign objects >2.5mm from touching the internal parts of the appliance
4: Prevent solid objects >1.0mm from entering
Prevent small foreign objects >1.0mm from touching the internal parts of the appliance
5: Dustproof
Completely prevent foreign objects from entering, and the amount of dust entering will not affect the normal operation of the appliance
6: Dustproof
Completely prevent foreign objects from entering, and can completely prevent dust from entering
The second characteristic number (number) indicates Degree of protection
The second number indicates the protection level
0: No protection
1: Prevent dripping water intrusion
Vertical dripping water will not cause harmful effects to the appliance
2: Prevent dripping water intrusion when tilted 15
Dripping water will not cause harmful effects to the appliance when the appliance is tilted 15
3: Prevent spraying water intrusion
Rainproof, or prevent water sprayed in a direction <60 degrees vertical from intruding into the appliance and causing damage
4: Prevent splashing water intrusion
Prevent splashing water from all directions from intruding into the appliance and causing damage
5: Prevent jetting water intrusion
Prevent jetting water from all directions from intruding into the appliance and causing damage
6: Prevent dust and waves from intruding
Prevent large waves from intruding into the appliance installed on the deck and causing damage
7: Prevent water intrusion during immersion
The appliance is immersed in water for a certain period of time or under a certain standard of water pressure to ensure that the appliance is not damaged by water intrusion
8: Prevent water intrusion during sinking
The appliance is sunk indefinitely under a certain standard of water pressure to ensure that the appliance is not damaged by water intrusion.
