The ToughNet TN-4500B Series M12 managed Ethernet switches are designed for railway applications, including rolling stock installations. The
switches use M12 circular connectors to ensure tight, robust connections, and guarantee reliable operation in industrial environments where
vibration and shock are commonplace. The TN-4500B Series Ethernet switches provide 8 to 28 Ethernet ports with or without IEEE 802.3at/af
compliant PoE functionality. The Gigabit models further feature up to 8 Gigabit Ethernet ports.
The 24 to 110 VDC wide power input range and isolated dual power inputs not only allow you to use the same type of power source at different
sites around the globe, but also increase the reliability of your communication systems. Furthermore, the -40 to 70°C operating temperature range
of the switches ensures they can be deployed in harsh environments. TN-4500B Series Ethernet switches are compliant with the mandatory
sections of EN 50155, covering operating temperature, power input voltage, surge, ESD, and vibration, as well as conformal coating and power
insulation, making the switches suitable for a variety of industrial applications.
