Standard For Judging The Sealing Performance Of Waterproof Cable Glands

The standard for judging the sealing performance of waterproof cable glands

At present, the main evaluation standard for the waterproof performance of the waterproof cable gland is based on the IP waterproof rating standard. Look at the waterproof performance of the waterproof connector, mainly look at the last two digits of the IPXX XX, X is from 0 to 6, the high grade is 6; the second digit is from 0 to 8, the high grade is 8; therefore the high waterproof of the waterproof connector gland, the rating is IP68.

Degree of protection against solid objects (one X)

0: No protection.

1: Prevent solid intrusion of more than 50mm, equivalent to the length of one hand;

2: Prevent solid intrusion of 12.5mm; equivalent to the length of one finger;

3: Prevent intrusion of 2.5mm. Equivalent to a wire or tool;

4: Prevent solid objects larger than 1.0mm from entering, equivalent to a wire or stripping wire;

5: To prevent damage caused by the full entry of dust;

6: Completely prevent dust from entering the cable gland stainless steel.

Water protection level (two X marks)

0: Not waterproof.

1: Prevent water droplets;

2: When the housing is tilted to 15 degrees, water droplets dripping into the housing have no effect;

3: No influence from water or rain from the 60-degree corner to the shell;

4: The liquid is splashed into the casing from any direction without harm;

5: Rinse with water without any harm;

6: Prevent strong water spray, which can be used in the environment inside the cabin;

7: Can withstand water in a short time;

8: Continuous flooding under a certain pressure.
