EN50155 Managed switch, 12/22 x 100BaseTX M12, 4x GbE


  • Industrial, L2 Ethernet switches with 12 or 22 ports
  • M12 connectors
  • Compliant with EN50155
  • μ-Ring for Redundant Cabling, recovery time<10ms
  • Supports TTDP for railway applications
  • Supports IEEE 1588 PTP V2
  • Supports SmartView for Centralized Management


The ITP series models are managed, industrial grade, L2 Fast Ethernet PoE (Power over Ethernet) switches that provide 12/22x 10/100Base-TX and 4x 10/100/1000Base-T(X) ports.  Up to 12/16 IEEE802.3at compliant PoE plus ports are classified as power source equipment (PSE) and provide up to 30 watts of power per port with a maximum power budget of 120W.

Housed in rugged wall mountable enclosures, these switches are designed for IEEE802.3af/at compliant powered devices(PDs), such as surveillance cameras, wireless access points, and IP phones. The PoE switches use M12 connectors to ensure tight, robust connections and guarantee reliable connections against vibration and shock.

M12 Railway Switch

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 a wide power input range of 24/48/72/96/110VDC(operating range 20 to 137.5VDC), this product series is especially suitable for rolling stock and track side installations.
