There are requirements for light touch switch waterproof. Different waterproof levels are used. How to distinguish these levels? The following will introduce these details to you.

 

Waterproof level overview:

 

IPxx level

 

The international industrial standard waterproof grade IP is close to the JIS waterproof grade of the Japanese industrial standard, which is divided into 9 grades of 0-8. The IP grade also specifies the dustproof.

 

Dustproof and waterproof

 

The protection level adopts the IP ×× level standard recommended by the International Electrotechnical Commission (IEC), and the level is different in different installation sites. Please refer to the following instructions for details. In the level standard, "×" is two digits, the first digit indicates the protection level for solid and the second digit indicates the protection level for liquid. There are 7 levels of solid protection, represented by 0-6; 9 levels of liquid protection, represented by 0-8.

 

Waterproof grade

 

0: no protection

 

1: There is no effect when water drops into the shell

 

2: When the shell is tilted to 15 degrees, the water drop into the shell has no effect

 

3: No effect of water or rain from 60 degree corner to shell

 

4: The liquid splashed on the shell from any direction has no harm effect

 

5: No harm by washing with water

 

6: Can be used in cabin environment

 

7: Water resistance in short time (1m)

 

8: Immersion in water for a long time under a certain pressure

 

Rank list

 

Ipx-0 has no waterproof protection

 

Ipx-1 equipment can provide waterproof protection equivalent to 3-5mm / min rainfall for 10 minutes under normal operation.

 

The level of IPX-2 is basically the same as that of ipx-1, but it can pass the waterproof test of 15 degrees upward in all directions.

 

Ipx-360 degree splash water-proof protection provides 2-5 minutes of 10 L / s flow rate and 80-100n / M pressure water-proof protection.

 

Ipx-4 is basically the same as ipx-3, but it can provide all-round and angle splash water-proof protection.

 

Ipx-5 is waterproof in all directions and angles, providing 2-3 minutes of 12.5 L / s flow rate and 30 n / M pressure.

 

Ipx-6 water-proof protection can last for 2-3 minutes to resist the depth of 3 meters, the flow rate of 100 L / min and the pressure of 100 N / m.

 

Ipx-7 can be immersed for 30 minutes in 1 meter under water.

 

Ipx-8 is completely waterproof and can be used in water continuously for a long time.
