NEU1042GZ-SFP Industrial Ethernet Switch, 4-Port Gigabit RJ45 + 2-Port 2.5G SFP, Unmanaged

NEU1042GZ-SFP is an unmanaged industrial Ethernet switch designed for stable connectivity and long-term operation in harsh environments. It features four 10/100/1000Base-T RJ45 ports for industrial endpoints and two SFP uplink ports for fiber expansion. The SFP uplinks support 1.25G and 2.5G modules, enabling longer-distance backbone connections and improved immunity to electromagnetic interference.

For industrial installation, NEU1042GZ-SFP adopts a fanless aluminum enclosure with IP40 protection and a compact DIN-rail form factor. The design supports reliable operation in control cabinets, roadside boxes, and factory enclosures where vibration, dust, and temperature changes are common. Redundant wide-range DC power input with reverse-polarity protection helps reduce downtime caused by unstable power feeds or wiring mistakes. A wide operating temperature range of -40°C to 75°C supports 24/7 deployments across demanding industrial sites.

Typical applications include factory automation networks, transportation infrastructure communication cabinets, tunnel monitoring systems, and remote edge aggregation. A common topology is to connect cameras, wireless bridges, industrial gateways, and PLC-related devices to the RJ45 ports, then use the dual SFP fiber uplinks to connect the edge cabinet to a central aggregation switch over longer distances. This approach simplifies wiring, improves stability in high-interference areas, and supports scalable expansion.

NEU1042GZ-SFP is CE, FCC, RoHS certified and comes with a 5-year warranty. Datasheet and technical documentation are available to support network planning, SFP module selection, installation, and commissioning.
