The EKI-9500 series switch is designed for railway application with rugged and high EMC performance, being suitable for networking solution for rolling stock and wayside applications. The EKI-9500 series provides M12 connectors for Ethernet/ console/ relay/ power-input connections to ensure tight & robust connectivity, and thus to guarantee reliable operation against environmental disturbances such as vibration and shock on train. The EKI-9508E-H/L is an Ethernet switch that provides 8 x Fast Ethernet M12 D-code port interface for all kinds of Ethernet connection. EKI-9508E-H/L features a "slim" design which can be easy deployed with its slender size and make the network deployment easier in crowded carriage/ cabinet.
