(International Electro Technical Commission). It classifies products according to

The IP (International Protection) rating system was drafted by the IEC (International Electro Technical Commission) to classify products according to their characteristics of dust resistance, protection from foreign objects, water resistance, and moisture resistance. The term

The foreign objects referred to here include tools, human fingers, etc. cannot touch the electrically charged parts inside the product to avoid electric shock.

Electricity. The marking method is: IPXX.

*** X: indicates dustproof grade

*** X: indicates the waterproof level

IP protection level is composed of two numbers, *** number indicates the dustproof, protection from external

IP protection level is composed of two numbers, *** numbers indicate the level of dustproof, prevent the intrusion of external objects; *** numbers indicate the degree of sealing against moisture, water intrusion. Number

The larger the number, the higher the level of protection, the two marked numbers indicate the level of protection as shown in Table I and Table II.

and Table II.

For example, IP54, it means the dustproof requirement level 5, waterproof level 4.

I: dust protection level:

0 no protection

1 against the intrusion of large solids;

2 to prevent the intrusion of solids greater than 12mm into the intrusion;

3 to prevent solids greater than 2.5mm from entering intrusion;

4 to prevent objects larger than 1mm solid entry intrusion;

5Protection against harmful dust accumulation;

6 completely prevent the dust from entering;;

II: Waterproof protection level:

0 No protection;

1 No effect of water drops into the housing;

2 no effect of water drops into the housing when the housing is tilted to 15 degrees;

3 water or rainwater from the corner of 60 degrees to the shell no effect;;

4 liquid from any direction to splash into the shell no harm impact;;

5 water rinsing without any harm;;

6 can be used in the cabin environment;

7 can be submerged in water for a short period of time (1m)

8 under a certain pressure for a long time submerged in water;
