Waterproof connector performance standards

The first digit mark protection class 

0: No protection 
Or things on the outside without special protection 
1: Prevention> 50mm intrusion of solid objects 
Prevent the body (palm) accidentally come into contact with electrical parts inside; prevent> 50mm intrusion of foreign objects 
2: Preventing> 12mm intrusion of solid objects 
Prevent the body (fingers) accidentally come into contact with electrical parts inside; prevent> 12mm intrusion of foreign objects 
3: Preventing> intrusion of solid objects 2.5mm 
Prevent> 2.5mm rather small foreign objects come into contact with electrical parts inside 
4: Preventing> 1.0mm intrusion of solid objects 
Prevent> 1.0mm rather small foreign objects come into contact with electrical parts inside 
5: Dust 
Completely prevent intrusion of foreign objects, and the amount of dust will not affect the normal operation of invasive appliances 
6: Dust 
Completely prevent intrusion of foreign objects, and can completely prevent dust intrusion 
Two. Range of applications 
Industrial environments, such as LED lighting, urban outdoor lighting, lighthouse, boat, aircraft, industrial equipment, cables, sprinkler, etc., need to use a waterproof connector
Military field applications due to more stringent requirements, a lot of use waterproof connector. Such as submarine connectors, submarine-launched missiles with connectors
The third number marked protection class 
0: No protection 
No protection 
1: to prevent dripping water intrusion 
Vertical drop of water droplets will not cause harmful effects on the electrical 
2: Tilt 15:00 still prevent dripping water intrusion 
Electric tilt 15:00 drip will not cause harmful effects on the electrical 
3: to prevent spraying water intrusion 
Rain, or to prevent the vertical <60 water spray direction invasive electrical damage 
4: to prevent splashing of water intrusion 
Prevent ingress of water splashing in all directions electrical damage 
5: to prevent ingress of water injection 
Preventing the intrusion of water injected in each direction of electrical damage 
6: Big Wave dust intrusion 
Mounted on the big waves intrusion preventing electrical damage to the deck 
7: to prevent flooding when water intrusion 
Electric immersion in water at a certain time or a certain standard pressure, to ensure no electrical damage caused by water 
8: to prevent the sinking water intrusion 
Electric sank under the water pressure at a certain standard indefinitely, to ensure no electrical damage caused by water
