RFID UHF eight-channel read-write module M2208

M2208 is a high-performance UHF read-write module developed by Xunyuan Technology with great concentration. It has 8 antennas and high-speed polling. The power and time can be configured separately to meet different coverage requirements. The maximum output power of the M2208 module can reach +30dBm, and with the 8dBi gain antenna, the reading distance can reach 20m, and the tag recognition rate greater than 800tags/s can be achieved.

M2208 is an eight-channel UHF RFID read-write module designed based on IMPINJ’s second-generation RF chip R2000. It is a UHF RFID read-write module specially designed for highly challenging application environments, with superior read-write performance.

M2208 has been verified by a large number of tests and long-term uninterrupted work (180 consecutive days), and its stability and reliability can fully meet the needs of development and use. Equipped with an eight-way SMA female antenna interface, it provides a standardized SDK development kit with rich functions, and users can develop according to project requirements in a short time.

The M2208 module is suitable for warehousing, logistics, clothing, production line management and other challenging application environments that require high RFID intensive reading performance.
