The Protection level of the dust-proof USB camera module is usually indicated by the IP (Ingress Protection) level, which consists of two digits. The first digit represents the dust-proof capability, and the second digit represents the water-proof capability. The following are the key points related to the protection level of the dust-proof USB camera module:
Dust-proof grade description
IP0X: No protection. The equipment has no protection capability against solid foreign objects.
IP1X: Prevents solid objects larger than 50mm from entering.
IP2X: Prevents solid objects larger than 12.5mm from entering.
IP3X: Prevents solid objects larger than 2.5mm from entering.
IP4X: Prevents solid objects larger than 1mm from entering.
IP5X: Dust-proof, allowing a small amount of dust to enter but not affecting the normal operation of the equipment.
IP6X: Completely dust-proof, no dust entering.
For dust-proof USB camera modules, achieving IP5X or IP6X ratings is a common choice, especially the IP6X rating, which can ensure the module operates normally in a completely dust-proof environment and is suitable for application scenarios with high dust-proof requirements.
Protection level testing and certification
Test standard: The dust-proof test is usually based on the IEC 60529 standard of the International Electrotechnical Commission (IEC) and the GB 4208-2017 standard of China. These standards define the protection level of the equipment casing against solid foreign objects and water.
Test method: Dust-proof testing is usually carried out in a dedicated dust-proof test chamber. A camera is placed inside the test chamber and maintained for a certain period of time to observe whether any dust enters the interior of the equipment.
Certification body: Conducting dust and water resistance tests through third-party testing institutions can effectively ensure the safety and stability of product use, meet relevant market requirements, and enhance consumer trust.
Suggestions for selecting protection levels
Application scenario: When choosing a dust-proof USB camera module, the required protection level needs to be determined based on the specific application scenario. Halimbawa, in outdoor or industrial environments, it might be necessary to select a higher dust-proof level to ensure the reliability and durability of the equipment.
Cost-effectiveness: Although a higher level of protection can provide better protection, it will also increase costs. Therefore, when choosing the protection level, cost-benefit factors need to be comprehensively considered.
