Advantech EKI-9520 Ethernet Switches

Advantech EKI-9520 Ethernet Switches deliver managed M12 networking for modern railway comfort and operational systems. The portfolio includes the EKI-9520G with 20 Gigabit Ethernet ports and the EKI-9520H with 14x 1Gbps ports plus 6x multigigabit ports supporting up to 10Gbps. Rugged housings, wide-range power inputs, and railway certifications support reliable installation in demanding transportation environments.

The Advantech EKI-9520G Switches support high-density onboard networks and optional PoE to power connected equipment directly. Its IP67 housing and M12 push-pull connector protect network connections in exposed environments. The EKI-9520H offers higher-bandwidth uplinks for large data volumes and supports 2.5Gbps, 5Gbps, and 10Gbps connections for applications that implement technologies such as Wi-Fi 6.

The EKI-9520 series includes Layer 2 management, network redundancy, traffic prioritization, multicast management, VLAN configuration, and security functions. These capabilities support rolling stock, wayside control, passenger information, public address, CCTV, HVAC, onboard Wi-Fi, and other railway communication systems.
