6.2 Mounting
Considerations
The following problems may occur when mounting multiple RDL150 readers in close proximity.
• The signal energy from one reader may interference with the read/write range of the other.
• Overlapping read/write fields can cause a single transponder to be read/write simultaneously
by two or more readers.
To ensure proper operation and optimal read/write range, take the following precautions:
Figure: Visualization of separation distances (vertical and back-to-back)
1. Mount all readers before tuning any of the readers
2. Ensure that the back-to-back distance is at least one meter
• Note 1:
If a metal plate is installed between the two readers, the back to back distance may
be ignored. However, read/write range will be reduced to approx. 240 mm.
• Note 2:
Reduced transponder read/write range and the simultaneous read/write of a trans-
ponder by both readers may result if the readers are installed less than 500 mm.
3. Ensure that the vertical separation distance is at least 500 mm. A more narrow vertical
separation gap may be used if the simultaneous read/write of a transponder by two
readers is acceptable.
