NEU2042GW-SFP Industrial Gigabit 4-Port RJ45 + 2x SFP Web-Managed Ethernet Switch

NEU2042GW-SFP is an industrial Gigabit Ethernet switch designed for stable edge connectivity and flexible fiber uplinks. It is built for industrial networks that require dependable operation in harsh environments and straightforward web-based configuration for daily management.

The switch provides 4 auto-negotiation 10/100/1000Base-T RJ45 ports for field devices and 2x 1G SFP slots for long-distance fiber connections. This combination supports mixed cabling in control cabinets and remote nodes, helping reduce electromagnetic interference on uplink paths while keeping installation simple at the device layer.

NEU2042GW-SFP includes practical Layer-2 features through web management, enabling VLAN segmentation, QoS priority, bandwidth control, and port mirroring for troubleshooting. Broadcast storm suppression helps protect the network from traffic spikes and misconfigurations, improving overall stability in multi-device industrial sites.

For high availability, NEU2042GW-SFP supports redundant ring networking with fast self-healing recovery, helping minimize downtime caused by a single cable or fiber break. This makes it suitable for ring and chain deployments across production lines, tunnels, pipelines, or roadside cabinets.

Typical applications include factory automation networks, PLC and SCADA cells, industrial gateways, and IP surveillance aggregation. A common topology uses SFP fiber uplinks to connect cabinets back to a control room or to form a fiber ring, while RJ45 ports connect PLCs, HMIs, industrial PCs, wireless APs, and IP cameras locally.

The compact fanless design supports DIN-rail mounting and is intended for continuous operation in demanding environments. NEU2042GW-SFP is CE, FCC, RoHS certified and comes with a 5-year warranty for long-term project assurance. Datasheet support is available to assist with selection, configuration, and deployment planning.
