Product introduction 
Waterproof connector : The general waterproof grade is IP68, which can be applied to the environment with water or outdoor wet places. The connector that can ensure the normal use of the internal mechanical and electrical properties of the connector under certain underwater or outdoor water seepage prevention conditions. Ensure the safety of outdoor electrical equipment. The electrical equipment is classified according to its dustproof and moistureproof characteristics. The IP protection level is composed of two numbers. The first number represents the level of electrical apparatus dust separation and prevention of external invasion. The second number represents the sealing degree of electrical apparatus against moisture and waterproof invasion. The larger the number is, the higher the protection level is.

The degree of protection indicated by the first characteristic number ( number ) 
 
First Digital Sign Protection Level 
 
0 : No protection 
 
No special protection against outsiders or objects 
 
1 : Preventing intrusion of solid objects > 50mm. 
 
to prevent the human body ( palm ) from being exposed to parts of the electrical apparatus by accident ; preventing invasion of > 50mm objects 
 
2 : Prevent the intrusion of solid objects > 12mm. 
 
preventing the human body ( finger ) from touching the parts inside the electrical appliance due to accidents ; preventing invasion of > 12mm objects 
 
3 : Prevent the intrusion of solid objects > 2.5mm. 
 
To prevent the small objects > 2.5 mm from contacting the parts inside the electrical appliance 
 
4 : Prevent the intrusion of solid objects > 1.0mm. 
 
To prevent > 1.0 mm tiny objects from contacting with the parts inside the electrical apparatus. 
 
5 : dust prevention
The invasion of external objects is completely prevented, and the amount of dust intruded will not affect the normal operation of electrical appliances. 
 
6 : dust prevention 
 
Total prevention of external intrusion and total prevention of dust intrusion 
 
The protection degree referred to by the second characteristic number ( number ) 
 
The second digital mark protection level 
 
0 : No protection 
 
No protection 
 
1 : Prevent drip intrusion 
 
Vertical drops do not cause harmful effects on electrical appliances 
 
2 : Still prevent dripping when tilted 15 
 
Drip water will not adversely affect electrical appliances when electrical appliances tilt 15 
 
3 : Prevention of spraying water intrusion 
 
Rainproof, or to prevent the vertical direction of < 60 spraying water into electrical damage. 
 
4 : Prevention of splash water intrusion 
 
Prevent water splashing in all directions from damaging electrical appliances 
 
5 : Preventing the intrusion of sprayed water 
 
Prevent water jetting in all directions from damaging electrical appliances 
 
6 : Dustproof wave intrusion 
 
Prevent waves from damaging electrical appliances installed on deck 
 
7 : Prevent water intrusion during immersion 
 
Electrical appliances immersed in water for a certain time or under a certain standard water pressure can ensure that electrical appliances are not damaged by water inflow 
 
8 : Prevent water intrusion when sinking 
 
Electrical appliances sink indefinitely under a certain standard water pressure to ensure that electrical appliances are not damaged by water
