The degree of protection of the waterproof connector is as follows:

Degree of protection (first number in the code) first characteristic

Brief description definition

6 dust can not enter the dust

The entire diameter of the object cannot exceed the gap of the outer casing

Degree of protection (second number in the code) second characteristic

Brief description definition

7 Anti-short immersion under normal temperature and pressure, when the shell is temporarily immersed in 1M

Deep water will not cause harmful effects

details as follows:

IP code: the degree of protection of the enclosure

This standard describes a system for classifying the degree of protection of electrical equipment enclosures. Submitted by the European Committee for Electronic Technology Standardization

Out, the protection level of the electrical equipment enclosure is divided into many categories, according to different numbers, the protection level of the product can be quickly and conveniently determined.

Take the code IP54 as an example:

IP indicates that this is a standard type

5 indicates the degree of protection in solids

4 indicates the degree of protection in the liquid

Degree of protection (first number in the code) first characteristic

Brief description definition

0 no protection

1 Anti-solid particles with a diameter of 50mm or more

Object

The tip of the object or solid particles of 50 mm diameter cannot penetrate completely.

2 Anti-solid particles with a diameter of 12.5mm or even larger

The tip of the object or solid particles of 12.5 mm diameter cannot penetrate completely.

3 Solid solid particles with a diameter of 2.5mm or more

The tip of the object or solid particles of 2.5 mm diameter are completely impenetrable.

4 Anti-solid solid particles with a diameter of 1mm or even larger

The tip of the object or solid particles of 1 mm diameter are completely impenetrable.

5 Dust protection dust entering can not be completely prevented, but will not reach

To the extent that it prevents the instrument from functioning properly and reduces safety.

6 Dust forbidden dust can not enter the object The entire diameter can not exceed the gap of the outer casing

Degree of protection (second number in the code) second characteristic

Brief description definition

0 no protection

1 Water droplets falling vertically from falling water will not cause harmful effects

2 Water droplets falling vertically when the casing is lifted up to 15°

Vertically falling water droplets do not cause harmful effects when the casing is lifted at any angle on either side of the vertical direction by no more than 15°.

3 Waterproof mist spray on any vertical side at any angle not exceeding 60° without harmful effects

4 Water repellent will not cause harmful effects on the shell from any direction.

5 Waterproofing does not cause harmful effects on the outer casing from any direction.

6 Anti-strong water spray will not cause harmful effects on the shell from strong water spray in any direction.

7 Anti-short immersion under normal temperature and pressure, when the shell is temporarily immersed in 1M deep water, it will not cause harmful effects.

8 Anti-continuous soaking is agreed between the manufacturer and the user, but under conditions of harsh conditions, continuous soaking in water will not cause harmful effects.

Application and precautions for protection standards:

In industrial applications, IP protection must be considered:

For standard industrial systems in closed buildings, IP54 protection = dust protection and splash protection.

IP65 protection is recommended for outdoor systems (automobiles, etc.). Ash and water proof.

Protection class ≤ IP40 is only for touch protection or only when the system is mounted on a rack (eg bracket).

IP67 protection should not be used in the outdoor warehouse's forklift system. The IP67 control system is usually used in improper situations if it is not used on a submarine.

Not all systems provide a high level of protection and there is no problem at all. High water resistance usually requires a completely closed installation, which usually causes heat dissipation problems. A system error caused by overheating may occur. Therefore, an additional heat sink is required.
