Orientation of magnetic fields of the SIMATIC RF382R Scanmode
For many applications it may be best to operate the reader so that the tags move from left to right (or from right to left) at a
certain distance in front of the narrow edge of the reader. This direction of movement uses the horizontal magnetic field of
the reader, see figure below.
You also have the option of moving the tags up and down (or down and up) past the narrow edge of the reader. This
direction of movement uses the vertical magnetic field of the reader.

Maximum magnetic field strength
The reader creates the maximum magnetic field about 13 mm below the upper reader edge. For the largest possible reading
range the tags you want to read should move in this range. This applies whether you use the horizontal or the vertical
magnetic field.
Figure 2 Line of maximum magnetic field strength
The area of the maximum field strength and, therefore, the maximum range is identified by a laser icon:
