The TN-5308 series of unmanaged Industrial Ethernet switches have been designed from the ground up for networking in transport applications. Rail and traffic approvals as well as e-marking for in-vehicle use make them one of the best qualified unmanaged switches on the market today. M12 connectors make them ideal for coping with the harsh shock and vibration of in-vehicle environments and up to 4 PoE ports can be used to power end devices such as intercoms, IP cameras and access points.
