Fast or Gb BASE-T Ethernet via M12 Connectors, -40°C to +85°C Operating

Manufacturer: duagon MEN

MEN's NM30 family is a range of 8-port fanless and maintenance-free managed Ethernet switches, developed specifically for rough environmental conditions in rolling stock and automotive applications.

The NM30 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.

The NM30 range provides eight channels at the front panel which are accessible through M12 connectors, cover different application requirements and are available with either 100 Mb or 1 Gb Ethernet interfaces.

The voltage supply for the NM30 Managed 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 NM30 is designed for fanless operation at temperatures ranging from -40 to +70°C. Its special aluminium housing has ingress protection IP40 and cooling fins which serve as a heatsink for the internal electronics, and in this way provides conduction cooling.

As a member of MEN's family of extremely rugged industrial box PCs, the NM30 provides the same flexibility and scalability, as well as a look and feel which is common to the family.
