Midrange RFID reader offers tailored customer solutions

The Ha-VIS RF-R300 UHF RFID reader from HARTING is a flexible unit which is claimed to combine robust construction for use in the toughest industrial environments with flexible modular software that allows it to be tailored to a wide range of applications.

With its software virtualisation concept, the reader is said to allow specific project and customer software to be installed alongside standard HARTING software. The modular software means that the reader can support a range of communication protocols, and the architecture also makes it possible to create and support customer-specific variants.

Supported communications protocols include LLRP, OPC-UA and MQ Telemetry Transport. Support for these and customer-specific variants is enabled by a software container concept based on embedded virtual computing; a LINUX base system contains the function containers.

Additional functions such as project-specific direction recognition algorithms and individual decisions based on additional information from sensors or transponders can be added later in an extra software container. This does not limit the system integrator to specific programming languages; anything supported by LINUX can be used.

The Ha-VIS RF-R300 is said to be 100% compatible with HARTING’s GS1 EPCglobal certified Ha-VIS Middleware, allowing users to create standards compliant RFID solutions.

The M12 HARTING connectors for both the Power-over-Ethernet connection and the eight general-purpose inputs and outputs with optional external power supply are suitable for rugged project environments.

The reader offers a maximum UHF output power of 0.5W on the two RP-TNC connectors, allowing it to fulfil all the tasks of a mid-range reader. Depending on the antenna and the coaxial antenna cable used, the reader is capable of reaching the maximum allowable UHF power of 2W ERP radiated at the antenna.
