The RFU610 transfers data on and off RFID-tags via ultra-high frequency (UHF). It identifies parts and products in the supply chain and delivers dense information for production process control. Process and evaluation unit and the antenna are combined in the smallest device of its kind, which allows flexible and easy integration in any production line. The contact-free RFID transfer withstands harsh environments and high temperature, which allows longterm usage of the devices. The housing corners have increasing radii, which has become a recognition sign of the product family. They enclose 3-color-status LEDs, which are highly visible from any side.
