What Are The Protection Measures For Industrial Switches?

No matter which manufacturer produces the Industrial Switch, more efforts should be made in terms of protection. Some products are not particularly outstanding in performance because the protection measures are not in place. In fact, the protection measures of industrial switches are reflected in many aspects, and each of them should be concerned.

First of all, dust prevention measures. Some products have good performance, but after a short period of use, there are quality problems. This is because there are problems with their own dust prevention performance. Most industrial switches basically have IP40 protection level, and they do a good job in dust prevention. After being disturbed by dust, all performances will not be affected.

In terms of anti-static, there are three aspects to be considered in the design of electrostatic discharge protection of the industrial switch. First, the electrostatic discharge protection design of the whole machine is generally adopted. Generally, the metal shell of the whole machine is used and the grounding terminal is designed. The whole machine shell is connected with the earth to form an equipotential body to prevent the harm of electrostatic discharge; Secondly, the electrostatic discharge protection design of the wiring port of the industrial switch can be divided into power interface, RJ45 interface, DIDO interface, etc., and the electrostatic discharge protection is designed independently according to the characteristics of different interface types; Then it is the electrostatic discharge protection design of the internal circuit to prevent the electrostatic protection during PCB processing, transportation and assembly.

Lightning protection: Practical application shows that lightning is the main culprit that causes the Ethernet switch hardware failure and affects the stability of the Ethernet switch. Ethernet switch power failure, port failure and cable failure caused by lightning occur from time to time. Therefore, in order to prevent lightning damage to the Ethernet switch, the lightning protection design of the industrial switch is very important. In terms of lightning protection, the protection level of each product is different, and the protection voltage of many products is even as high as 6000V. I'm afraid that such ideal protection measures can only be created by brand industrial switch manufacturers. Although some products also have lightning protection function, they may not meet the needs of the public, so pay more attention when purchasing.

There are many protective measures for industrial switches, including pressure test. Pressure test can conduct comprehensive evaluation and test on the Ethernet switch, and verify all links in the R&D and production process. The support test includes not only functions, performance, stability, but also automation and factory inspection. Can the industrial switch ensure the stability of performance in the harh environment? If the industrial switch is applied to the harsh environment, the performance of the product will disappear, which means that there is a problem with the adaptability of the product to the environment. In this case, the product cannot be used normally. Therefore, most of the industrial switch manufacturers will carry out the pressure test in advance, and will only push it into the market after ensuring that all the pressure tests meet the standards.

In addition, industrial switches must undergo multiple inspections before leaving the factory. Radiation protection test is an essential part. In case of radiation, it will interfere with the performance of products. For the purpose of electromagnetic compatibility, the enclosure of the industrial switch is all metal, and has been grounded, which not only enhances the ability to resist the interference of other products on itself, but also greatly reduces its own electromagnetic radiation, so the performance of the product will be more durable and more stable.

In the process of selecting and purchasing industrial switches, everyone's focus is different, but the manufacturers of industrial switches are bound to spend a lot of time on protection measures. Only after the protection measure is in place can the product's application life be extended.

Houshi Network has been focusing on the field of Ethernet transmission and access products for many years. After years of development, it has established its own development direction, and has developed its own characteristic fist products in the industry, from the commercial switch initially developed to the national industrial switch, from data exchange products to artificial intelligence products. Houshi Network has been working hard for China's network communication industry to make its own unique contribution in the field of Ethernet transmission and access!
