The RFID transponder (also called RFID tags) from SICK work on the basis of high frequency (HF) or ultra-high frequency (UHF). The tags work passively and use the energy of the RFID read/write device for data transmission. Both HF and UHF transponders follow a standard which is valid worldwide. The large range of transponders regarding dimensions, size, storage size, ambient operating temperature, mounting and read range enable use in many different applications. RFID tags can save up to 64 bits of data and can be identified up to a read range of 10 m. Together with the RFID read/write devices, they create reliable and future-proof identification solutions.
