The EKI-9508E-P Series consists of unmanaged 8-port Fast Ethernet PoE switches purpose-built for railway and rolling stock applications. With M12 D-coded connectors, these switches provide tight, vibration-proof connections that withstand the demanding mechanical and environmental stresses found in railway and industrial environments.
Each model delivers 8 x 10/100 Mbps M12 ports with PoE/PoE+ capability, supporting IEEE 802.3af (15.4 W) and IEEE 802.3at (30 W) per port. Depending on the model, the total PoE power budget is up to 90 W (PH) or 60 W (PL), enabling direct powering of IP cameras, access points, and VoIP devices across the train or trackside.
Designed to comply with the EN50155 railway standard and EN50121-3-2 EMC requirements, the switches offer guaranteed performance under voltage fluctuations, temperature extremes, vibration, and shock. Dual power inputs further enhance reliability: the PH model supports 72/96/110 VDC, while the PL model supports 24/48 VDC. Integrated reverse polarity and overload current protection safeguards the system against electrical faults.
The compact, slimline IP40 metal housing is optimised for railway cabinets and confined spaces, with wall-mount installation. Operating reliably from -40 to 70 °C, the EKI-9508E-P series ensures dependable service even in extreme environmental conditions.
With Layer 2 switching, 8K MAC address table, and jumbo frame support up to 9 KB, the series provides efficient data handling for onboard networks. Backed by a proven industrial design and full compliance with railway standards, the EKI-9508E-P Series is the ideal unmanaged Ethernet switch for mission-critical transportation and rolling stock deployments.
