The Muon (Model A528B), OEM reader of the easy2read© Family, is an UHF multiregional compact reader for high performances UHF RFID applications.
With programmable output power in 8 steps from 10dBm to 27dBm, the reader can detect tags up to 3m of distance (depending on antenna and tag dimensions).
Due to its form factor, the module is specifically designed to be easily embedded either in battery powered devices, such as industrial handhelds, or fixed reading point devices, such as printers, point of sales, self-service kiosks or industrial automation readers.
The radio frequency core of the module allows to achieve fast reading/writing and operation in dense reader and dense tag environments for top-class rated performances.
The A528B complies with and can operate in both European and US regulatory environments and, due to its multiregional capabilities, it’s ideal for integration in devices requiring compliance to different geographical regions.
