Accessories Overview Specifications


The ToughNet TN-4500A Series M12 managed Ethernet switchesare designed for railway applications, including rolling stock andwayside installations. The switches use M12 and other circular connectorsto ensure tight, robust connections, and guarantee reliable operationin industrial environments where vibration and shock are commonplace.The TN-4500A Series Ethernet switches provide 12 or 24 fast EthernetM12 ports with or without IEEE 802.3at/af compliant PoE functionality,and the Gigabit models have 4 Gigabit Ethernet interfaces with PoEand optional bypass relay functionality. In addition, the fiber modelsprovide 2 Gigabit fiber interface ports with an embedded 2 km multimodefiber transceiver. The PoE switches are classified as power sourceequipment (PSE).

The switches provide up to 30 watts of power per port, and can beused to power IEEE 802.3at/af compliant powered devices (PDs), suchas IP cameras, wireless access points, and IP phones. The 24 to 110VDC wide power input range and isolated dual power inputs not onlyallow you to use the same type of power source at different sitesaround the globe, but also increase the reliability of your communicationssystem. Furthermore, the -40 to 70°C operating temperature range ofthe switches ensures they can withstand deployment in harsh environments.TN-4500A Series Ethernet switches are compliant with the mandatorysections of EN 50155, covering operating temperature, power inputvoltage, surge, ESD, and vibration, as well as conformal coating andpower insulation, making the switches suitable for a variety of industrialapplications.
