Features and Benefits

  • M12 connectors and IP40 metal housing
  • Supports IEEE 802.3/802.3u/802.3x
  • Complies with a portion of EN 50155 specifications
  • -40 to 75°C operating temperature range (T models)


The ToughNet TN-5308 series M12 unmanaged Ethernet switches are designed for industrial applications in harsh environments. The TN series switches use M12 connectors to ensure tight, robust connections, and guarantee reliable operation against environmental disturbances, such as vibration and shock. The TN-5308 series Ethernet switches provide 8 Fast Ethernet M12 ports, support IEEE 802.3/802.3u/802/3x with 10/100M, full/half-duplex, MDI/MDI-X auto-sensing, and provide an economical solution for your industrial Ethernet network. Models with an extended operating temperature range of -40 to 75°C are also available. The TN-5308 series Ethernet switches comply with those EN 50155 requirements that make products more suitable for rolling stock applications, including operating temperature, power input voltage, surge, ESD, and vibration, making the switches suitable for a variety of industrial applications.

White Paper: Optimized Ethernet Redundancy for Inter-Consist Networks Download

Network redundancy is a critical factor in ensuring passenger safety and journey reliability in onboard railway communications for both intra-consist and inter-consist Ethernet networks. In addition, railway operators are looking for ways to more efficiently allocate resources and serve passenger demands. For example, metropolitan rail services may want to run trains with fewer consists during off-peak hours but longer trains with more consists during rush hour. Railway operators can also serve multiple markets and conserve track assets by connecting multiple consists with different destinations into one train if they will travel along the same route for at least part of the journey. 

This white paper describes how Dynamic Ring Coupling helps railway operators provide seamless onboard Ethernet redundancy with both rapid recovery times and automatic Ethernet switch configuration even when consists are rearranged mid-journey.
