Phoenix Contact SFNB 8TX Industrial Ethernet Switch

The Phoenix Contact SFNB 8TX is an industrial Ethernet switch that provides eight Ethernet ports for direct interconnection of field devices and control systems. As part of the FL SWITCH SFNB family, it is designed to operate within industrial networks where reliable data exchange between controllers, sensors, actuators, and HMIs is required. The model designation “8TX” identifies eight transmission ports, enabling parallel data paths and straightforward expansion of an Ethernet backbone on the factory floor. Suitable applications include factory automation, machine networking, and process control networks where multiple devices must be networked to a central controller or switch fabric. This switch supports standard Ethernet connectivity to support common industrial networking topologies and serves as a node for segmenting devices and aggregating network traffic.
