RFA621-000 UHF RFID antenna

RFA621-000 UHF RFID antenna

Intelligent RFID communication

The SICK RFA621-000 is a circularly polarised Industry-compliant UHF RFID antenna. The rugged design was developed specially for the challenging application conditions in industrial environments and outdoor areas. Depending on the transponders, read ranges of up to 10 m can be achieved.

Optimally aligned antenna characteristics prevent faulty readings, therefore ensuring high process stability. Reliable operation is possible thanks to rugged design − even under rough industrial environments.

Product traceability and anti-counterfeiting solutions require reliable automatic identification products. SICK offers the three most common industrial identification technologies: laser-based scanners for 1D codes, image-based 1D and 2D code readers, and RFID readers. Integrated interfaces enable the readers to communicate inside industrial networks and innovative functionality makes commissioning and operation easy.

Radio-based RFID technologies in the HF (high frequency) and UHF (ultra high frequency) ranges supplement SICK’s industrial automation portfolio. In applications where process-relevant data is modified remotely, RFID makes it possible to store data on writable and rewritable media. In contrast to optical solutions, RFID provides reliable identification of all objects – despite dirt and everyday wear.
