Fast or Gb BASE-T Ethernet via M12 Connectors, -40°C to +85°C Operating
MEN's NM31 family is a range of 8-port fanless and maintenance-free managed Power over Ethernet switches, developed specifically for extreme and rough environmental conditions in rolling stock applications.
High Speed, High Efficiency and Extensive Protocols
The NM31 range of managed switches provides the additional ability to configure, manage and monitor the LAN which allows more control over how data travels through the network and who has access. The use of the identical firmware as provided for the G101 Ethernet Switch simplifies complex administration and reduces efforts for administrator training. Versatile Application Possibilities
Versatile Application Possibilities
The NM31 range provides eight channels at the front panel, accessible through M12 connectors and cover different application requirements including PoE+, IEEE802.3at type 1 and type 2 (previously af and at) compliant, and either 100 Mb or 1Gb Ethernet interfaces.
Compliant to Railway Standards
The voltage supply for the NM31 Managed Power over Ethernet Switch is designed for maximum flexibility and supports wide range input supply voltages from 14.4 to 154 VDC, and meets all EN50155 class S2 requirements for voltages ranging 24 to 110 VDC.
The NM31 is designed for fanless operation at temperatures ranging from -40 to +70°C. The NM31 features IP40 protection when surface-mounted and cooling fins which serve as a heatsink for the internal electronics, and in this way provides conduction cooling.
Familiar Family Concept
As a member of MEN's family of extremely rugged industrial box PCs, the NM31 provides the same flexibility and scalability, as well as a look and feel which is common to the family
