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. For instance, 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.
