Brief introduction
HYM750P UHF RFID reader uses R2000 chip, which complies with EPC C1G2 protocol, its working frequency is 840~960MHz，with LBT function(Customizable). It supports dense reader working mode (DRM). Max Power is 31dbm.With standard 8dBi antenna，the reading distance can reach 15meters, maximum identifying speed can reach 400/S; with simple power supply and interface circuit, a high-performance RFID system can be established. It is suitable for logistics, costume, medical industry, and complex assets management, etc. It is well used in high performance fixed readers.
