NEU1021GZ Industrial Ethernet Switch 2xGbE RJ45 1x2.5G Fiber Unmanaged

NEU1021GZ is an unmanaged industrial Ethernet switch built for reliable connectivity in industrial automation and harsh electrical environments. It provides two 10/100/1000Base-T RJ45 ports for local devices and one optical uplink supporting 100M, 1G and 2.5GBaseFX, enabling long-distance transmission and improved immunity to electromagnetic interference.

Designed for plug-and-play deployment, NEU1021GZ helps expand machine networks without configuration or ongoing maintenance. Store-and-forward switching, a stable hardware design and industrial-grade components support consistent performance in control cabinets and on automation equipment.

Key features and benefits include wide-range redundant DC 9–52V power inputs, reverse-polarity protection, and a fanless metal enclosure for maintenance-free operation. The wavy aluminum housing improves heat dissipation, while the IP40 protection level supports installation inside industrial cabinets. With operating temperature from -40°C to 75°C, the device is suitable for long-term operation in demanding sites.

Typical applications include connecting PLCs, HMIs, industrial PCs, remote I/O and sensors to a factory fiber backbone, linking control cabinets across production lines, and extending Ethernet to high-EMI areas such as motor rooms. A common topology is a cabinet-level star where local controllers connect to the two RJ45 ports and the fiber port uplinks to a central aggregation switch, or a distributed topology where multiple cabinets uplink via fiber to a control room core switch.

NEU1021GZ is designed for industrial reliability with anti-surge, anti-lightning, anti-electromagnetic interference and anti-vibration capabilities. It is compatible with mainstream industrial automation protocols, including Modbus TCP, Ethernet/IP, Profinet RT and EtherCAT for industrial Ethernet networking. The product is CE, FCC, RoHS certified and includes a 5-year warranty.

Technical documentation support is available, including a Datasheet to assist with selection, installation and system integration.
