EN50155 unmanaged switch, 8 x 100BaseTX


  • Unmanaged industrial grade Fast Ethernet switch, with 8 x 10/100Base-TX Ethernet ports and is designed for industrial applications in harsh environments
  • Ethernet ports utilize M12 connectors to ensure water-tight, robust connections and guarantee reliable operation against environmental disturbances such as vibration and shock
  • Compliant with EN50155, covering operating temperature, power input voltage, surge, ESD, vibration, and shock, thus making it suitable for industrial applications in vehicle, rolling stock and factory automation
  • Use M12 connector anti vibration and shock for vehicle, rolling stock, and railway applications
  • Build-in 2 bypass port to avoid one or more nodes power fail in a bus structure to collapse the network
  • Redundant dual DC input power 12/24/48VDC (8.4~60VDC)
  • Rugged metal, IP40 protection and fanless design
  • Wide operating temperature -40~75°C
  • CE, FCC, EN50155, EN50121-4 and EN45545-2 for railway certified
  • Industrial Grade EMS, EMI, EN61000-6-2, EN61000-6-4 certified
