Overview

The Tau (Model A941M), OEM reader of the easy2read© Family, is an UHF multi protocol module for long range applications.
With programmable output power in 256 steps from 17dBm to 32dBm, the reader can detect tags up to 10m of distance (depending on antenna and tag dimensions).
Due to its form factor, the module is specifically designed to be easily embedded into a user’s infrastructure/ devices requiring UHF tag programming and reading.
The A941M is fully compliant to the European regulations ETSI EN 302 208 and ETSI EN 300 220 and supports Philips UCODE EPC 1.19, ISO 18000-6B, and EPC Class1 Gen2.
The A941M is ideal for customers who want to design their own RFID solution and require a long range RFID reader engine featuring up to 4 antennas.
