(1) Function: Industrial Ethernet switches are closer to industrial network communication, such as interconnection of various fieldbuses, redundancy of equipment, and real-time requirements of equipment.
(2) Performance: This is mainly reflected in the different parameters applicable to the external environment. In addition to particularly harsh environments, industrial environments also require EMI electromagnetic compatibility, temperature, humidity, dust prevention, etc. Especially, temperature has the most extensive impact on industrial network equipment.

The shell of Ethernet switches is generally packaged in plastic or iron shells, and the price difference is not significant; The appearance is usually delicate, compact, and easy to install.

The application fields of industrial Ethernet switches in the market include power and rail transportation, industrial control automation, road traffic control automation, building automatic control systems, mine automatic control systems, oilfield control automation, hydropower station control automation, power system control automation, computer room monitoring systems, etc.
The environment of industrial sites is worse than ordinary environments, at least in terms of vibration, moisture, and temperature. Ordinary switches are not designed to withstand various situations that occur in industrial environments. Ordinary switches cannot work in such harsh environments for a long time and are often prone to failures, which increases maintenance costs. It is generally not recommended to use commercial switches in industrial environments. In order to enable switches to be used in such harsh environments, switches that can adapt to this environment are produced. The reliability of industrial grade switches includes power failure, port interruption, relay output alarm, redundant dual DC power input, active circuit protection, overvoltage and undervoltage automatic circuit breaker protection.

Currently. In the domestic industrial Ethernet switch market, power and rail transportation are the key application areas of industrial switches, accounting for 70% of the market. There are approximately 50 active manufacturers in the Chinese industrial Ethernet switch market.

There are around 15 foreign-funded manufacturers, 3-4 Taiwanese manufacturers, and around 30 local manufacturers in the Chinese industrial Ethernet switch market. Local brands are predominant among local manufacturers.

Nearly 70% of the sales of industrial Ethernet switches enter the market through distribution. Foreign funded enterprises usually sell their products through distribution, while domestic enterprises use direct sales.

The constraints of domestic industrial Ethernet are largely due to the lack of a unified universal standard, uneven product quality, significant price differences, and difficulty for users to choose. Meanwhile, industrial Ethernet technology and fieldbus technology have coexisted for a long time. Fieldbus technology will continue to exist for a long time, which limits the development of industrial Ethernet switches to a wider range of application areas.

China's future industrial Ethernet switches will experience greater development with the continuous advancement of industrial automation and the continuous promotion of industrial Ethernet technology applications. From a technical perspective, real-time communication, stability, and security are the focus of industrial Ethernet switch products.

With the development of network technologies such as wireless networks and Bluetooth, industrial Ethernet switches will continue to move forward. From a product perspective, multifunctionality is the direction of development for industrial Ethernet switches.
