What is the difference between IP65, IP67, and IP68 waterproof grades?

The IP in the waterproof grade is the abbreviation of Ingress Protection, which evaluates the protection grade of the enclosure of electrical equipment against the intrusion of foreign objects. Not only connectors, but also lamps, mobile phones, and electrical appliances have waterproof grades.

Among the two digits behind IPXX, the first digit represents the level of contact protection and foreign object protection, the number ranges from 0 to 6; the second digit represents the waterproof level, the number ranges from 0 to 8. So IP68 is the highest waterproof and dustproof for electrical equipment enclosures grade.

We all know that the higher the waterproof and dustproof level, the better, but not all application scenarios require a particularly high waterproof level. Manufacturers will also recommend suitable waterproof handsets according to the user's application scenarios.

IP65 means that it can completely prevent dust from entering, and can be rinsed with water for a short time.

IP67 means that it can completely prevent dust from entering, and can be immersed in water for a short time under a certain pressure.

IP68 means that it can completely prevent dust from entering, and can be immersed in water for a long time under a certain pressure.
