RFline U4 UHF Long Range Reader

Industrial UHF RFID Reader for Long-Range Identification

RFline U4 is designed for demanding industrial and logistics applications, ideally suited for reading distances greater than 10 meters. Equipped with rugged M12 connectors and a robust metal housing, it is the ideal solution for integration into machines, forklifts, and conveyor systems.

The device is powered by the latest IMPINJ E710 reader chip, offering excellent read performance and high flexibility for industrial and IoT environments. Supporting UHF RFID technology EPC Class 1 Gen 2 (ISO 18000-63) within a frequency range of 865–868 MHz, the RFline U4 enables reliable and fast identification processes.

With up to 33 dBm RF output power via a mono-static antenna port, the reader achieves read rates of more than 950 tags per second depending on the tag IC used. Real-time temperature monitoring ensures stable operation even under challenging environmental conditions.

A comprehensive Software Development Kit (SDK) is provided for seamless integration into Linux, Windows, and controller-based systems. The SDK includes full documentation, command protocols, source code examples, and a user-friendly Windows demo application.
