In the customized cabinet design, the protection level has the following requirements:

** Dust proof requirements ** :

- IP5X grade requirements can prevent most of the dust from entering, can not be completely prevented, but the dust will not enter a large amount and affect the normal operation of the equipment.

- IP6X requires complete protection from dust.

** Waterproof requirements ** :

- IPX1 indicates that vertical drip has no harmful effect.

- IPX2 can withstand 15° tilt dripping.

- IPX3 is required to prevent water spraying in the range of 60° from the vertical direction.

- IPX4 resists splashing in all directions.

- IPX5 can withstand low pressure water spray at close range.

- IPX6 can withstand high pressure water spraying.

- IPX7 indicates immersion in water at specified time and pressure without damage.

- IPX8 is a higher level of protection against prolonged flooding.

In addition, there may be other special requirements according to the specific application scenario, such as corrosion protection, chemical protection, etc. Different protection levels correspond to different environmental adaptability. During the design, you need to accurately evaluate the protection level requirements of the actual application scenario to ensure that the cabinet can operate safely and reliably in the corresponding environment. For example, the outdoor use of the cabinet usually requires a higher level of waterproof and dustproof, and the indoor environment may be relatively lower, but if there are special conditions such as wet or dusty, it is also necessary to improve the protection level accordingly.
