Industrial automation sensors company SICK has released a new UHF RFID read-write device focused on assembly applications in conveyor systems in tight spaces, as well as on handling and assembly lines. SICK’s RFU61x reader, with integrated Ethernet and fieldbus interfaces, is intended to provide an alternative to 13.56 MHz HF RFID technology used at assembly sites. The company calls the RFU61x the smallest and smartest industrial UHF reader on the market. The device measures 80 millimeters by 92 millimeters by 38 millimeters (3.15 inches by 3.6 inches by 1.5 inches). SICK demonstrated the new reader at this year’s RFID Journal LIVE! conference, held this month in Phoenix, Ariz.

One feature, says Philipp Bordne, SICK’s RFID product manager, is the design of antenna characteristics that provide a well-defined reading zone. In that way, tagged items, such as small components under assembly, can be reliably identified in spaces where stray reads would be detrimental, despite the fact ...
