In the complex scenarios of industrial production, from automated control next to high-temperature furnaces to data transmission in humid mines, the stable operation of network equipment is the key to ensuring production efficiency and safety. As a core device that transmits both data and power, it is crucial to choose an adaptable model for harsh environments. This article will combine Newbridge's products to analyze the key points of selection and recommend applicable models for you.
1. Operating temperature range: Stable guarantee in extreme environments
The temperature of the industrial environment changes dramatically, from the extreme cold outdoors in the north to the high temperature in the steelmaking workshop, which is difficult for ordinary switches to withstand. Industrial PoE switches must have wide temperature working capabilities. Newbridge's NB-IES8000 series has an operating temperature range of -40℃ to 75℃. Through industrial-grade component selection and efficient heat dissipation design, it ensures 7×24 hours of stable operation under extreme temperatures. When purchasing, you need to choose a switch whose operating temperature can fully cover the usage scenario according to the actual deployment environment to avoid downtime due to temperature.
2. Protection level: Resist erosion by harsh pollutants
Industrial sites filled with dust, humidity, and corrosive gases place high demands on the protection performance of switches. The IP protection level is an important measurement standard. For example, IP67 means complete dustproof and can be immersed in water for a short time without damage. Newbridge's NB-IES6000 series reaches the IP67 protection level. The metal shell is combined with a sealed design and equipped with an M12 aviation connector to effectively resist dust, water vapor and oil pollution. It is suitable for outdoor and highly polluted environments such as ports and petrochemicals.
3. Electromagnetic compatibility (EMC): Accurate data transmission in complex electromagnetic environments
In industrial plants, strong electromagnetic interference generated by large motors, inverters and other equipment can easily affect network signal transmission. Newbridge industrial-grade PoE switches strictly follow the IEC/EN 61000-4 standard and reduce the impact of electromagnetic interference through multi-layer PCB board shielding, filter circuit optimization and other technologies. For example, the NB-IES5000 series can ensure zero packet loss and no delay in data transmission even in strong electromagnetic environments such as power substations.
4 Power adaptability: Coping with unstable power supply
The power supply at industrial sites fluctuates frequently, and voltage instability and power outage restart are common. High-quality industrial-grade PoE switches must support wide voltage input and power redundancy functions. The Newbridge NB - IES7000 series supports 9 - 57VDC wide voltage input, and the dual power module design realizes redundant power supply. It also has overcurrent, overvoltage, and surge protection to ensure equipment safety and continuous operation when the power supply is abnormal.
5. PoE power supply capacity: meeting the power needs of diverse equipment
PoE technology simplifies industrial wiring, but different devices have different power requirements. The IEEE 802.3af standard single port supplies 15.4W, IEEE 802.3at can reach 30W, and some switches also support higher power. The Newbridge NB - IES9000 series has a PoE output power of 370W for the whole machine, and a single port supports a maximum of 60W, which can simultaneously provide stable power supply for high-power devices such as high-definition industrial cameras and smart sensors.
