EN50155 8-port M12 Unmanaged PoE Ethernet Switch Includes M12D-4P-IP68 x 8, A-CAP-M12M x 8, M12A-5P-IP68 and A-CAP-M12F x 1

Features

NSM-208The NSM-208PSE-M12 is designed for industrial applications in harsh environments. The M12 connectors ensure tight, robust connections, and guarantee reliable operation, even for applications that are subject to high vibration and shock.

The NSM-208PSE-M12 PoE switch provides 8 fast Ethernet M12 ports with 8 IEEE 802.3af compliant PoE ports. The switch is classified as power source equipment (PSE) and provides up to 15.4 W of power per port. The Ethernet switch supports IEEE 802.3/802.3u/802/3x with 10/100M, full/half-duplex, MDI/MDI-X auto-sensing, and provides an economical solution for your industrial Ethernet network.

The NSM-208-M12 provides a wide 12 to 53 VDC power range to fit all the common power standards found in industrial automation, without external power converters. The wide power input lowers installation and maintenance costs.

  • Each port supports both 10/100 Mbps speed auto negotiation
  • 8 PoE ports with Power Sourcing Equipment (PSE) operation 
    (NSM-208PSE-M12)
  • Over-temperature, over-current and over/under-voltage detection (NSM-208PSE-M12)
  • 8-port 10/100 Mbps M12 type connector with IP40 protection
  • EN50155-certifi ed for harsh railway standards
  • Automatic MDI/MDI-X crossover for plug-and-play
  • Store-and-forward architecture
  • Full duplex IEEE 802.3x and half duplex backpressure flow control
  • Auto-detection of PD (powered devices) and automatic power management (NSM-208PSE-M12)
  • Operating temperatures, -40 ~ +75°C
