EN50155 Managed Switch, 8 x 10/100BaseTX, 2 x GbE (SFP or UTP)


  • Managed - Web, SNMP, RMON
  • IP67 industrial grade
  • L2 Fast Ethernet switches  8x Fast Ethernet UTP plus 2x GbE SFP / UTP Ports
  • M12 connectors
  • Compliant with EN50155
  • STP, RSTP, MSTP, ITU-T G.8032 Ethernet Protection Ring (ERPS)
  • Build-in 2 bypass GbE UTP ports
  • Supports IEEE1588 PTP V2
  • Supports SmartView for Centralized Management


The ITP series models are managed, industrial grade, L2 Fast Ethernet switches that provide 8x Fast Ethernet UTP plus 2x GbE SFP or 8x Fast Ethernet UTP plus 2x GbE UTP Ports. Housed in rugged wall mountable enclosures, these switches are designed for the harshest environments. All ITP series switches use M12 connectors to ensure water-tight, robust connections and guarantee reliable connections against vibration and shock. These models are also compliant with EN50155, covering power input voltage, surge, EFT, ESD, vibration and shock, making these switches suitable for industrial applications, such as vehicle, rolling stock, or vessel. With an IP67 rating, to protect against dust and water submersion, they are particularly useful in environments with extreme temperature, high humidity, oil, dust and in outdoor environments requiring water-proof applications, such as IP surveillance or city security.

Railway switches


These switches  support IEEE 1588 PTP V2 for precise time synchronization.  Each port may be configured independently  to operate in Ordinary-Boundary,  Peer to Peer Transparent Clock,  End to End Transparent Clock, Master, or Slave mode.  Accuracy is measured in nanoseconds, making it suitable for time sensitive applications such as mobile phone networks, military systems and large scale financial networks.


Bypass Protection

Bypass protection is provided by 2 RJ45 ports which are connected together in the event of a power failure. In a ring structure, this ensures that the rest of the network carries on functioning normally. When power is available, a relay opens and normal operation resumes.
