The Position of Industrial POE Switch Is Steadily Rising

With the technical development of the industrial Internet of Things, Internet terminal devices (surveillance cameras, wireless network APs, etc.) are becoming more and more colorful. Before the power over Ethernet technology has taken place, the power supply method for Internet terminal devices is generally to select independent cables and power plugs for power supply. In the specific operation, the overall cost rises due to the lack of suitable socket installation points. How to complete the power supply and communication of Internet terminal equipment in the simplest way on the industrial production site? With the occurrence of supporting industrial poe switches, the problem of switching power supply wiring and Internet wiring of field terminal equipment can be reasonably handled, that is, under the Ethernet interface Cat. 5 cabling system architecture, DC power supply to terminal equipment can also transmit data signals at the same time.

Industrial PoE switch is also referred to as Ethernet power supply, which refers to the technology of transmitting power to equipment through twisted pair in Ethernet, without changing the existing Ethernet cabling infrastructure, and providing DC power supply for equipment while transmitting data signals to terminals. It can supply power to network phones, wireless IP devices, IP cameras, hubs, computers, and other devices that are not convenient to set up additional power lines.

Four advantages of industrial PoE switch:

1. Material saving

POE only needs to install and support one cable, which is simple and space saving, and the device can be moved at will. Only two pairs of network cables are needed between the industrial PoE switch and the camera to transmit the camera network signal, audio signal, control signal, alarm signal and power the camera at the same time. There is no need to pull the power cable and install the transformer, which will save the power cable and transformer in the construction cost. If the average distance between the camera and the switch is 75 meters, a four port industrial PoE switch will, 300 meters of power line and 4 transformers can be saved. If the power line is 1.5 yuan per meter, 450 yuan can be saved. If the power line is 15 yuan per meter, 60 yuan can be saved for 4 transformers. As the power cord is saved, the cost of PVC pipe is saved accordingly. Originally, the network cable and power cord need to be run separately, saving 300 meters of PVC pipe and various pipe fittings and PVC glue, saving 400 yuan, saving a total of 910 yuan of material costs. It also costs tens of yuan to buy an ordinary five port switch, and then it can buy a POE switch for tens of yuan more. So what you really need to focus on is the overall cost of the project, not the unit price of several industrial PoE switches.

2. Long distance transmission

By using Ethernet transmission technology, industrial PoE switches can transmit POE power supply and network signals to 150 meters, which completely breaks the myth that the network cable cannot exceed 100 meters. Although we did not fully meet this standard in the experiment, we recommend that its use distance be guaranteed to be within 140 meters during the actual use of the project. More than two years of trouble free operation fully proves the reliability of POE technology.

3. Save labor costs

Many live devices, such as video surveillance cameras, need to be installed in places where it is difficult to deploy AC power. POE eliminates the need for expensive power supplies and the time spent installing power supplies, saving costs and time. After using the POE switch, only one network cable can be pulled, which saves a lot of labor, saves the installation cost of transformer without transformer, saves the wiring work of several joints and saves the adhesive tape and welding work. At the same time, the use of POE for power supply also reduces the failure points.  This has undoubtedly saved a lot of labor costs for engineers in today's era when the industry is bigger than the materials.

4. Convenient and quick use

The industrial PoE switch not only has several POE power supply network ports connected to the lower level, but also has an upper optical port designed to connect the upper level with the lower level, which is convenient for users to use remotely through optical fiber. This design concept with customer needs as the purpose has been unanimously praised by all users. Like data transmission, POE can monitor and control the device by using Simple Network Management Protocol (SNMP). The POE power supply terminal equipment can only supply power to the equipment that needs power supply. Only when the equipment that needs power supply is connected can the Ethernet cable have voltage, thus eliminating the risk of electric leakage on the line. A single UPS can provide power supply for all related equipment in case of power failure. Users can automatically and safely mix existing devices and POE devices on the network. These devices can coexist with existing Ethernet cables, making network devices easy to manage.

With the increasing application of video surveillance, networking, intelligence and high-definition are the development direction of this industry. In recent years, the use of industrial PoE switches has been expanding in the transportation, new energy and security industries, and their position has also gradually risen. Industrial PoE switches have solved the problem of installing separate power modules and power sockets near each terminal device. It is unnecessary to deploy separate power systems on site, which greatly reduces the wiring and management costs of deploying terminal devices.

Our industrial PoE switch is equipped with rich POE interfaces, which is convenient for building wiring and maintenance; Equipped with a full set of industrial grade electronic components, it can operate continuously all day long and is stable at the aerospace level; In addition, it supports gigabit redundant ring network communication, comprehensive network protection, wide temperature and wide pressure, and can work under full load at - 40~85 ℃, adapting to harsh industrial working environment, such as building security, factories, highways, railways, etc.
