The protection level of industrial switches is often referred to as the IP protection index. IP refers to “ingress protection, access protection”, and the protection level is drafted by the IEC (International Electrotechnical Association). So, when we are purchasing industrial switches, what is the appropriate IP level of the industrial switches?

Classify electrical appliances according to their dust-proof and waterproof characteristics. IP protection level is generally composed of two numbers. The first number represents the intrusion index of dust and foreign objects (tools, hands, etc.), the highest level is 6; the second number represents the waterproof sealing index of electrical appliances, the highest level It is 8. The larger the number, the higher the protection level.

When purchasing an industrial switch, users usually choose an industrial switch with a suitable protection level according to their use environment. For industrial switches, the IP protection level is an index of dust and water resistance, so what causes the difference in the index? This is mainly related to the shell profile of the switch. Industrial switches mainly include aluminum alloy profiles and galvanized steel plates. In contrast, aluminum alloys have a higher degree of protection.

For industrial switches, a general protection level of more than 30 can adapt to harsh industrial environments, and can ensure safe, reliable, and stable communications for industrial switches.
