What are the different types of IP protection levels? 10

Plate B belongs to the electrical application sector, which is divided into: B0 (Siemens series PLC) B2 (Schneider series PLC) B3 (A-B series PLC) B4 (automation system related knowledge) B5 (industrial instrumentation related) B6 (low-voltage electrical part) B8 (medium and high voltage electrical part) B9 (electrical automation other).

IP1X: It means that the spherical test tool with a diameter of 50mm cannot enter the void and enter the inside of the product;

IP2X: Represents a spherical object with a diameter that cannot penetrate the void of the product;

IP3X: The diameter of the object cannot be penetrated through the product gap;

IP4X: Metal wire with a diameter of 1mm cannot penetrate the product void and affect dangerous parts;

IP5X: placed in the dust box, open the lid to check that there is no dust inside the product, if it does not affect the performance of the product, it can also determine the load standard requirements;

IP6X: The product needs to be pumped under negative pressure, placed in a dust box, opened and inspected, it is dust-tight, and no dust can enter to determine that it meets the standard requirements;

The IP (Ingress Protection) protection rating system is drafted by the International Electronic Technical Commission (IEC), which classifies electrical appliances according to their dustproof and moisture-proof characteristics. The external objects referred to here, including tools, human fingers, etc., should not touch the live parts of the electrical appliances to avoid electric shock. The IP protection level is composed of two numbers, the first number indicates the level of dust and foreign intrusion of the electrical appliance, and the second digit indicates the airtightness of the electrical appliance against moisture and waterproof intrusion, and the larger the number, the higher the protection level.

IP rating: is an abbreviation for Ingress ProtectionIP ratingIt is the level of protection against the ingress of foreign objects in the enclosure of electrical equipment, **YesInternational Electrotechnical CommissionIEC 60529, which was also adopted as the American National Standard in 2004.

In this standard, for the protection of electrical equipment enclosures against foreign objects, the format of the IP rating is IPXX, where XX is two Arabic numerals.

The first marking number indicates the contact protection and foreign object protection level, and the second marking number indicates the waterproof protection level, and the specific protection level can refer to the following **.

IP is the code name used by the international community to determine the protection level, and the IP level consists of two numbers, the first number indicates dustproof; The second number means waterproof, and the higher the number, the better the protection.

Examples of IP protection levels:

The IP consists of the letter IP, the 1st characteristic digit, the 2nd characteristic digit, additional letters, and supplementary letters. Its format is as follows: IP 4 3 C s.

The first characteristic digit indicates the level of the device against dust and foreign intrusion, and the highest level is 6. The second characteristic number indicates the degree of containment of the device against moisture and water intrusion, and the highest level is 8. The higher the characteristic number, the higher the protection level, and when the protection level is not required, the characteristic number can be replaced by the letter "x".

The additional letter in the third digit indicates a hazardous part that can be prevented from contact.

The supplementary letter in the 4th digit indicates additional supplementary information. Additional and supplementary letters can be omitted, so the IP rating of most devices usually includes only 2 characteristic digits.

Although the highest test level of IP protection is IP68, the common claim levels are IP22, IP33, IP44, IP54, IP55, IP65, IP66, IP67, IP68, etc. In general, IP43 is claimed for indoor equipment and IP66 is claimed for outdoor equipment.

The IP protection level is composed of two numbers, the first number indicates the level of dust protection and prevention of foreign intrusion, and the second number indicates the degree of airtightness of moisture and water intrusion.

Representation: The protection level is mostly expressed by two numbers followed by IP, and the numbers are used to clarify the level of protection.

The first digit indicates the range of resistance to fine dust in the device, or how well people are protected from hazards in a sealed environment. Represents the level of protection against the ingress of solid foreign matter, the highest level is 6;

The second digit indicates how waterproof the device is. Represents the level of protection against water ingression, and the highest level is 8.

The international IEC529 standard divides the protection of electronic instruments into 10 levels, and the IP protection level is composed of two numbers, the first number indicates the level of dust proof and foreign object intrusion of electrical appliances, and the second number indicates the degree of sealing of electrical appliances against moisture and waterproof immersion, and the larger the number, the higher the protection level.

The first number indicates dust resistance, and the rating standards are as follows:

The second number indicates waterproof, and the rating standards are as follows:

Targeting with defeat is the specific introduction of the IP protection level.

1. Definitions. IP protection level: indicates the dust and moisture resistance characteristic level of electrical equipment, which consists of IP and two-digit delay numbers.

IP is the prefix of "Ingress Protection", and the number indicates the level of protection.

The first digit: indicates the level of the electrical equipment's ability to prevent the intrusion of foreign objects, the highest level is 6;

The second digit: indicates the degree of containment of electrical hail equipment against moisture and water intrusion, and the highest level is 8.

2. IP30

Dustproof level: prevent the intrusion of solid foreign objects with a diameter larger than that;

Waterproof Rating: No protection. That is, there is no special protection against water or moisture.

3. IP50

Dustproof level: Prevent foreign objects and dust. That is, it completely prevents the intrusion of foreign objects, and has a certain dust-proof performance, but does not completely prevent the incursion of dust, and the amount of dust intrusion will not affect the safe operation of electrical equipment;

Waterproof Rating: No protection. That is, there is no special protection against water or moisture.

For more information, please refer to the related materials.

4 indicates the dustproof level, and X indicates the waterproof level. Therefore, IP4X is the enclosure to prevent the ingress of solids larger than 1mm.

If a characteristic number is not required, the letter X is used instead (or XX if both letters are omitted). Additional letters and/or supplementary letters may be omitted and do not need to be replaced.

When more than one supplemental letter is used, it should be in alphabetical order. When enclosures are installed in different ways to provide different levels of protection, the manufacturer should indicate this level of protection on the instructions for the corresponding installation methods.
