5-Port Unmanaged Ethernet Switch Connects Your Devices to a LAN
This space-saving switch with EIP QoS transmits data over an Ethernet network. Five auto-negotiating 10/100 Mbps ports send data only to the devices designated to receive it, which improves the efficiency and potential throughput of the network.

Supports Intelligent QoS for PROFINET, EtherNet/IP and IEC 61850 GOOSE Traffic
Eaton’s iQoS (Intelligent Quality of Service) is designed to support PROFINET, Ethernet/IP (EIP) and GOOSE traffic by ensuring reliable and consistent data delivery in industrial networks. Based on the characteristics of aforementioned industrial protocol communication, iQoS automatically recognizes and prioritizes traffic with industrial protocol mentioned to maintain stable network performance under normal operating conditions. This built-in mechanism helps ensure deterministic behavior for critical industrial data streams without requiring user configuration, making it well suited for plug-and-play deployments in OT environments. Note: While Eaton devices such as the NGI-U05A support automatic QoS handling through iQoS, they do not provide manual traffic classification or port-level priority configuration. For applications requiring customized traffic policies—managed network switch with advanced QoS functionality should be deployed.

Ruggedized Metal Housing Built to Last in Harsh Environments
The compact NFI-U05A adds 10/100 Mbps Ethernet capacity to your industrial and commercial applications, such as factory floors, warehouse operations and other environments with space constraints and wide temperature ranges. The industrial-grade high-strength case withstands vibration, shock and free fall. It can also operate in extreme temperatures ranging from -40 to 75 degrees Celsius (-40 to 167 degrees Fahrenheit).

Unmanaged Switch Requires Little to No Configuration
Quickly connect your network devices with little to no configuration. LEDs indicate when the switch is powered on and which Ethernet ports are showing activity. The NFI-U05A supports MAC address auto-learning and auto-aging for efficient routing, as well as automatic MDI/MDI-X crossover detection for plug-and-play functionality. IEEE 802.3x flow control allows smooth transmission of large files.

Flexible Mounting Options
The open-type device may be DIN mounted using the pre-installed rail clip, which mounts firmly to any standard 35 mm DIN rail. It may also be wall mounted using the rear mounting holes. A 3-pin 12–48VDC terminal block supplies power input. Device power must be supplied by SELV circuit.

TAA-Compliant for GSA Schedule Purchases
The NFI-U05A is compliant with the Federal Trade Agreements Act (TAA), which makes it eligible for GSA (General Services Administration) Schedule and other federal procurement contracts.
