CIDRW Head
The area for communications with ID Tags varies substantially according to the installation orientations
and the background conditions (metals, noise, etc.). Check the communications area before deciding
the installation position.
For details on actual communications distances, see Characteristic Data depending on Conditions of
Use in Appendix.
Refer to page 81.
■ Positional Relationship between the CIDRW Head and the ID Tag
The communications area differs according to the positional relationship during communications.
■ Data Reading and Writing
The communications distances for reading and writing are not the same; the distance is shorter for
writing. Therefore, when data is to be both read and written, take the distance for writing as the refer-
ence distance when installing the CIDRW Head and the ID Tag.

Communications area (purely illustrative) Explanation
Coaxial The maximum communications area is
obtained when the center lines of the CIDRW
Head and the ID Tag coincide.
Parallel The maximum communications area is
obtained when the center point of the
antenna on the CIDRW Controller is aligned
with the center line of the ID Tag.
Vertical When the center point of the antenna on the
CIDRW Head is aligned with the center line
of the ID Tag, the communications area is
substantially reduced.
