The distance for reading and writing
Balluff can provide RFID solutions suitable for various processes. During the use and installation of RFID coding block, the RFID code block must be installed within the sensing range of the read-write head before it can be read and written normally.
The area that can be sensed is called the free zone.
Generally, the farther the read-write distance is, the smaller the free area of the allowable deviation of the code block is.
When the same read-write head corresponds to different code blocks, different free area size will lead to different read-write distances.
