Hello, this is the Network Technology Alliance site.
In today's information society, the rapid development of network technology has made Ethernet switches an important part of network communications. However, with the development of industrial automation technology, Ethernet switches specifically targeted at industrial environments have emerged, namely industrial Ethernet switches. This article will delve into the differences between industrial Ethernet switches and regular Ethernet switches, and why we need industrial Ethernet switches.
Let’s follow Rui Ge’s steps and enter today’s article!

1. Basic concepts of Ethernet switches
An Ethernet switch (Ethernet Switch) is a network device used to connect multiple computers, printers, servers and other devices to achieve communication between these devices. When an Ethernet switch receives a data packet sent by a device, it can determine the target device of the data packet, and then send the data packet directly to the target device, instead of sending the data packet to all connected devices like a network hub .
1.1 Features
- Usually made of plastic casing, suitable for general indoor environments.
- Transfer speeds are usually 1 Gbps or less.
- Not durable and not suitable for use in harsh industrial environments.
- It is mainly used for data communication and has low environmental requirements.
1.2 Application areas
-
Home network : used to connect various devices in the home, such as computers, smartphones, smart TVs, etc.
-
Office : Connect employee computers, printers, and other devices on an office network to share resources and data.
-
Small Business : A LAN for small businesses to connect employee workstations and servers.
2. Basic concepts of industrial Ethernet switches
Industrial Ethernet Switch is an Ethernet switch specially designed for industrial environments. Due to the particularity of the industrial environment, such as extreme changes in temperature and humidity, electromagnetic interference, etc., ordinary Ethernet switches may not work properly in the industrial environment. Therefore, industrial Ethernet switches are usually more robust and can operate normally in various harsh environments.
2.1 Features
- Metal shell, impact and vibration resistant, suitable for industrial locations.
- Supports higher data transfer speeds such as Gigabit Ethernet (1 Gbps) or 10 Gigabit Ethernet (10 Gbps).
- It has the characteristics of dustproof, waterproof and anti-corrosion, and is suitable for harsh industrial conditions.
- Supports more network management and security functions, such as VLAN, QoS, RSTP, etc.
2.2 Application areas
-
Manufacturing : Industrial Ethernet switches are used in automated production lines to ensure real-time data transmission and communication between machines. This helps improve production efficiency and quality control.
-
Transportation Systems : Traffic signal control, train and subway systems all rely on Industrial Ethernet switches to ensure safe and efficient operation.
-
Energy Industry : Energy industries such as power, oil and gas require highly reliable communication systems, and industrial Ethernet switches meet these needs.
-
Medical equipment : Medical equipment and hospital information systems require reliable network connectivity to ensure patient safety and data confidentiality.
3. The difference between industrial Ethernet switches and ordinary Ethernet switches
Industrial Ethernet switches and conventional Ethernet switches are key network devices used to connect multiple devices in a local area network (LAN). Although they may look similar in appearance, there are some key differences between them that are important in different application scenarios.
Here are the main points of difference between the two:
3.1 Appearance
-
Industrial Ethernet switches : Typically have a rugged housing, such as a metal housing, to resist physical shock and vibration. This design makes it suitable for use in industrial environments and provides a longer service life.
-
Conventional Ethernet switches : Usually in a lightweight plastic or metal case with a stylish appearance, they are mainly used in office or home environments, and do not have the durability to match industrial environments.
3.2 Climate environment
-
Industrial Ethernet switches : Designed to withstand a wide range of climatic conditions, including extreme temperature ranges and humidity levels. This makes them suitable for use outdoors and in non-climate controlled industrial environments.
-
Regular Ethernet switches : More suitable for use in temperature-stable, controlled indoor environments, as they may not be equipped to handle extremes of temperature or humidity.
3.3 Electromagnetic environment
-
Industrial Ethernet switches : Designed to withstand electromagnetic interference, which is common in industrial environments with high-voltage equipment and machinery. They feature shielding technology to minimize signal interference.
-
Regular Ethernet switches : May not provide the same level of protection because they are generally not required to operate in an electromagnetic interference environment.
3.4 Power supply design
-
Industrial Ethernet switches : Typically equipped with redundant power options to ensure continued operation in the event of a power failure. This is critical for critical industrial applications, where downtime can have serious consequences.
-
Regular Ethernet switches : Typically rely on a single power supply and may not have redundant power options.
3.5 Service life
-
Industrial Ethernet Switches : Engineered for longer life and long-term reliability to withstand the harsh conditions found in industrial environments.
-
Regular Ethernet switches : Typically designed optimally for more controlled environments, so life expectancy may be shorter.
Rui Ge has compiled the above differences into a table so that everyone can make a better comparison:
| features | Industrial Ethernet switch | Regular Ethernet switch |
|---|---|---|
| Exterior | Metal housing, resistant to shock and vibration | Lightweight plastic or metal housing, stylish design |
| climate environment | Adaptable to a wide range of climatic conditions, including extremes of temperature and humidity | Suitable for temperature-stable, controlled indoor environments |
| electromagnetic environment | Anti-electromagnetic interference design, using shielding technology | May not provide equivalent protection against electromagnetic interference |
| Power supply design | Redundant power options ensure continuous operation | Typically relies on a single power source |
| Service life | Longer service life and long-term reliability | Expected service life may be shorter |
| Application areas | Industrial control systems, manufacturing, transportation systems, power industry, etc. | Home, office, small business networks and more |
4. Why do you need industrial Ethernet switches?
Industrial environments have much higher requirements for network communications than office environments. In an industrial environment, communication failure at any point may lead to major production accidents. Therefore, the stability and reliability of industrial Ethernet switches are crucial. In addition, equipment in industrial environments usually needs to operate 24 hours a day, which also places higher requirements on the durability of Ethernet switches.
5. Conclusion
Generally speaking, industrial Ethernet switches are significantly different from ordinary Ethernet switches in terms of design concept, performance and functions. Industrial Ethernet switches provide a higher level of environmental adaptability, network performance and functional features for the special needs in industrial environments. This makes industrial Ethernet switches play a key role in industrial environments, ensuring the stability and reliability of network communications.
Although the cost of industrial Ethernet switches is higher than ordinary Ethernet switches, considering its importance in industrial environments, such investment is worthwhile. Therefore, the selection and use of industrial Ethernet switches is very necessary for any business operating in an industrial environment.
In the future, with the further development of industrial automation and informatization, industrial Ethernet switches will be more and more widely used in various industrial fields, and their importance and value will become more and more obvious. Likewise, industrial Ethernet switch technology will continue to advance to meet the growing demands of industrial environments.
