The EKI-9508G Series provides unmanaged Gigabit Ethernet switching in a rugged format tailored for railway and rolling stock applications. Equipped with eight 10/100/1000 Mbps M12 X-coded ports, the series guarantees vibration-resistant and secure connectivity in harsh, high-EMC environments.
Designed to meet the stringent EN50155 and EN50121-3-2 railway standards, the switches ensure dependable operation against voltage fluctuations, shock, vibration, and electromagnetic interference. Two model variants are available: the EKI-9508G-H supports 72/96/110 VDC input, while the EKI-9508G-L supports 24/48 VDC input, both with reverse polarity and overload protection for fault-tolerant performance.
Built in a slim IP40-rated metal enclosure (122.5 x 179.4 x 71.8 mm), the EKI-9508G fits easily into compact railway cabinets and wall-mount installations. It is optimised for rolling stock deployment, offering reliable operation across a -40 to 70 °C temperature range and up to 95% relative humidity (non-condensing).
Supporting Layer 2 switching functions, including an 8K MAC address table and jumbo frames up to 9 KB, the EKI-9508G provides high-throughput performance for bandwidth-intensive applications. With a typical system consumption of only ~5 W, it offers an efficient, low-maintenance solution for gigabit connectivity in transport and industrial automation.
With proven IEC shock, vibration, and freefall certifications, the EKI-9508G Series delivers robust Ethernet performance in demanding railway environments, backed by industrial-grade reliability and design.
