EN50155 Unmanaged Ethernet Switch with 5x 10/100/500Base-T(X), 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 TXES-150-M12 is an unmanaged Ethernet switch with 5x10/100/500Base-T(X) which is specifically designed for the toughest and fully compliant with EN50155 requirements.  TXES-150-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 -40oC to 75oC can satisfy most of the operating environment.  The TXES-150-M12 can be easily adopted in all kinds of applications and provides the most rugged solutions for your network.  Therefore, the switch is one of the most reliable choices for rolling stock Ethernet applications.


While installed in the train, TXES-150-M12 is mainly used for in-train monitoring and Entertainment service due to its high-speed Ethernet connection. Devices connected will be IP camera or CCTV for the use of train surveillance. As an unmanaged Ethernet Switch, TXES-150-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.
