IP68 grade

- Jan 08, 2019-

The IP68 is the highest level of connector waterproof rating. To evaluate the waterproof performance of the waterproof connector, mainly look at the two digits XX of the IPXX, the first digit X is from 0 to 6, the highest level is 6; the second digit X is from 0 to 8, the highest level is 8;

Therefore the highest waterproof rating of the connector is IP68.

IP is the abbreviation of Ingress Protection. The IP rating is the protection level against foreign objects in the electrical equipment casing. The source is the International Electrotechnical Commission's standard IEC 60529, which was also adopted as the US national standard in 2004. In this standard, for the protection of foreign objects in electrical equipment enclosures, the IP rating format is IPXX, where XX is two Arabic numerals, the first marked number indicates contact protection and foreign object protection rating, and the second marked number indicates waterproof protection rating. IP is the international code used to determine the degree of protection. The Ip level consists of two numbers. The first number indicates dustproofing; the second number indicates water resistance. The higher the number, the better the team length.

The relevant test basis in China is GB 4208-2008/IEC 60529-2001 "Shell protection grade (IP code)" standard requirements, the conformity assessment test for the enclosure protection grade of various products; the highest detection grade IP68. Regular product inspection levels include: IP23, IP44, IP54, IP55, IP65, IP66, IP67, IP68.

The purpose of the test criteria is as follows:

Specify the degree of enclosure protection specified by the electrical equipment load;

Prevent the human body from approaching dangerous parts inside the casing;

Prevent solid foreign matter from entering the equipment inside the casing;

Prevents harmful effects on equipment due to water entering the enclosure.
