Rugged Network Switch

Rugged Science NS-4000 series managed Ethernet switches are designed for military and marine use. The NS-4000 is compliant with the EN50155 standard, and is a managed Gigabit Redundant Ring Ethernet switch with 8x10/100/1000Base-T(X) P.S.E. ports and 4x10/100/1000Base-T(X) ports which is specifically designed for the toughest and fully compliant with EN50155 requirement. The switch support Ethernet Redundancy protocol, Rugged-Ring (recovery time < 30ms over 250 units of connection), Rugged-Ring, R-Chain, MRP and MSTP (RSTP/STP compatible) can protect your mission-critical applications from network interruptions or temporary malfunctions with its fast recovery technology. It is specifically designed for the toughest industrial environments.


The NS-4000 uses M12 military-style connectors to guarantee secure connections. The NS-4000 also supports Power over Ethernet, which transmits power and data to remote devices over standard twisted-pair cable in an Ethernet network.  Each NS-4000 switch has 8x10/100/1000Base-T(X) P.S.E. (Power Sourcing Equipment) ports, and  includes 2 sets of bypass ports that protect the network from failures and Network maintenance by ensuring network integrity during power loss. And support wide operating temperature from -40o C to 70o C. NS-4000 can be centrally managed by Rugged-Vision, and web-based interface.
