UHF RFID Reader Product specification 1 Product description The RDM-900S05 UHF RFID Reader is independently researched and developed by our company and is designed with the industry's highest performance Impinj R2000 chip. Based on the dynamic Q algorithm of Impinj and brand-new data model, we independently invented the latest "adaptive dynamic Q anti-collision algorithm V3.0" and applied this algorithm to all R2000 readers independently developed by our company.
UHF RFID Reader Product specification An algorithm designed for reading a small number of tags. Ultra-high tag response speed. ➢ High power output capability Choose PA chip with stronger amplifying output ability, the maximum output power of the reader can reach 35dBm. The PA still maintains a linear state when the output is 33dBm. Larger output power can achieve a longer recognition distance, and at the same time, in specific applications, greater output power can activate tags with weaker sensitivity.
UHF RFID Reader Product specification operating temperature of the system in real time. ➢ Outstanding thermal design All the heating devices have a heat-conducting structure. There is a large area of heat sink contact at the bottom of the reader. The thermal coupling interface adopts thermal conductive silicone grease with high thermal conductivity, which is not volatile at high temperature. ➢ Excellent stability 24 hours × 365 days work without crashing.
