EN50155 Unmanaged Ethernet Switch with 8GE, M12 connector, 24VDC



ORing’s TransporterTM series un-managed Ethernet switches are designed for industrial applications, such as rolling stock, vehicle, and railway applications.  The TGXS-1080-M12 is an un-managed Ethernet switch with 8x10/100/500/1000Base-T(X) which is specifically designed for the toughest and fully compliant with EN50155 requirement.   TGXS-1080-M12 EN50155 Ethernet switch uses M12 connectors to ensure tight, robust connections, and guarantee reliable operation against environmental disturbances, such as vibration and shock.  In addition, the wide operating temperature range from -40 oC to 75oC can satisfy most of the operating environment.  Therefore, the switch is one of the most reliable choices for rolling stock and highly-unmanaged Ethernet application.

 While installed in the train, TGXS-1080-M12 is mainly used for in-train monitoring and Entertainment service due to its high-speed Gigabit Ethernet connection. Devices connected will be IP camera or CCTV for the use of train surveillance. As an unmanaged Ethernet Switch, TGXS-1080-M12 is not able and will not be used for any control-related application. Its main function is simply forwarding the Ethernet packet from one Ethernet-based device to another Ethernet device which is all connected to the Switch.
