Have you ever confused what is the IP Rating and how to select suitable IP Rating of Metal Cable Glands?
Believe you will get some help after you finish reading this article.

It’s necessary to know what is an IP rating mean before select correct Metal Cable Glands.
The IP (Ingress Protection) Rating of a Metal Cable Glands indicates whether a product can withstand water or dust penetration.
And the rating consists of the letters IP followed by two digits, The first number denotes foreign body ingress protection, the second moisture.
The higher the number the better the protection.Sometimes a number is replaced by X, which indicates that the enclosure is not rated for that specification.
In general ,you can refers to the level of sealing effectiveness as defined in IEC 60529 (Formerly BS EN 60529:1992) to check the IP rating of Metal Cable Glands.

The most common IP rating are probably 65,66,67 and 68 in Metal Cable Glands.
These are defined below for your quick reference.

IP65 Enclosure – IP rated as “dust tight” and protected against water projected from a nozzle.
IP66 Enclosure – IP rated as “dust tight” and protected against heavy seas or powerful jets of water.
IP 67 Enclosures – IP rated as “dust tight” and protected against immersion. for 30 minutes at depths 150mm – 1000mm
IP 68 Enclosures – IP rated as “dust tight” and protected against complete, continuous submersion in water.

Moreover, the extent of the ingress protection implied by each number have been described in the following table:

Protection Level	Solids Rating (First Number)	Liquids Rating (Second Number)
0 or X	Not rated for protection against contact or ingress (or no rating supplied).	Not rated (or no rating supplied) for protection against ingress of this type.
1	Protection against solid objects larger than 50 mm (e.g. accidental contact with any large surface of the body, but not deliberate body contact).	Protection against vertically dripping water. No harmful effects when the item is upright.
2	Protection against solid objects larger than 12 mm (e.g. accidental finger contact).	Protection against vertically dripping water. No harmful effects when tilted up to 15° from normal position.
3	Protection against solid objects larger than 2.5 mm (e.g. tools).	Protection against water sprayed directly at any angle up to 60° off vertical.
4	Protection against solid objects larger than 1 mm (e.g. small objects such as nails, screws, insects).	Protection against splashing water from any direction. No harmful effects when tested for at least 10 minutes with an oscillating spray (limited ingress permitted).
5	Dust protected: partial protection against dust and other particulates (permitted ingress will not compromise the performance of internal components).	Protection against low-pressure jets. No harmful effects when water projected in jets from 6.3 mm nozzle, from any direction.
6	Dust tight: full protection against dust and other particulates.	Protection against powerful water jets. No harmful effects when water projected in jets from 12.5 mm nozzle, from any direction.
7	N/A	Protection against full immersion at up to 1 meter depth for up to 30 minutes. Limited ingress permitted with no harmful effects.
8	N/A	Protection against immersion beyond 1 meter. Equipment is suitable for continuous immersion in water. The manufacturer may specify conditions.
