Precautions for selecting industrial switches

what kind of industrial Ethernet switches are most suitable for your factory's current applications? This is really a disturbing thing, because many factors need to be considered, such as the working environment, whether redundancy is needed, managed and non managed, future maintenance and scalability, and so on

■ consideration of working environment: including temperature range, EMC, protection grade, installation method, power supply, etc. Industrial Ethernet switches are designed for those environments that are not suitable for commercial switches, such as those with extreme temperature, high vibration and strong electromagnetic noise

■ choose tube or non tube switches: if the network is relatively simple, you can choose plug and play non tube switches; For the convenience of maintenance in the future, it may be necessary to choose tubular switches. Only if the tubular switches can be actively innovated by China's automotive industry, can the ring topology connection be achieved

■ it also needs to meet relevant industrial standards: for example, marine switches should meet the standards of ship structure; If it is used in dangerous places, it should meet the corresponding certification standards; Rail transit, highway and other transportation industries also have their own standards
