The read/write station operates in the UHF frequency range and is optimized for use in industrial applications involving shorter distances. The device reads and writes passive tags acc. to EPC Generation 2 ( ISO/IEC 18000-63). The read/write station is compliant with the relevant transmission regulations.

The read/write station can be used in the USA and Canada.

Wide range of options supported for filtering data. The read/write station has an IO-Link interface and is connected via a M12 connector. The user can monitor the status of the read/write station using the integrated LEDs.

The read/write station has a typical detection range of around 1 meter; this range is determined by the tag used and can be adjusted by configuring the transmission power. Other influencing factors include the setup and installation of the specific application and the surrounding materials, particularly metal. The read and write distances for the relevant tag, which are detailed separately, have been established in a test laboratory under ideal conditions. For the actual read and write distances under real conditions, the combination of read/write station and tag must be tested in the desired application.
