The ITP series models are managed, industrial grade, L2 Fast Ethernet switches that provide 8x Fast Ethernet UTP plus 2x GbESFP 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.

Technical Notes

EN50155 Switches for Rail, Metro and Transport Applications

The ITP series of Ethernet switches are certified to EN50155. This internationally recognised standard particularly addresses the deployment of electronic equipment on rolling stock for railway applications. However the ITP range are equally well suited for use in any harsh environment. The ITP Ethernet switches are vibration and shock resistant and provide stable and reliable operation for mission-critical applications.
