The ToughNet TN-5510A-2GLSX-ODC series M12 managed Ethernet EN50155 Switch, designed for railway applications, such as rolling stock and wayside installations. The TN series switches use M12 and other circular connectors to ensure tight, robust connections, and guarantee reliable operation against environmental disturbances, such as vibration and shock. In addition, the 24 to 110 VDC wide power input range and isolated 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 communications system. The TN-5510A-2GLSX-ODC switches provide up to 8 Fast Ethernet M12 ports, and 2 ports on the down side to provide the Gigabit fiber interface with an embedded 2 km multimode fiber transceiver. Moreover, the -40 to 75°C operating temperature and IP54-rated waterproof and dustproof enclosure allow deployment in harsh environments. The TN-5500A series Ethernet switches are compliant with 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.
