1. Overview of Industrial PoE Switches
1.1 Definition and Core Features
Industrial PoE switches are network devices specifically designed for harsh industrial environments. They combine Ethernet switching and Power over Ethernet (PoE) functions, enabling the direct power supply and data transmission to terminal devices through network cables. Their core characteristics are robustness, durability, stability, and reliability.
These characteristics are exemplified in modern managed switches, such as the Baudcom 10-Port Gigabit Managed Industrial POE Switch (BD-S33108PFM). This switch is designed for harsh conditions with a wide operating temperature range (-40°C to 75°C), supports key industrial protocols, and provides PoE power adhering to IEEE 802.3af/at standards, making it a robust connectivity and power solution for demanding applications.
