Influence of Surrounding Metal on Reader/Writer (for Reference Only)
The Reader/Writer can be surface-mounted or it can be embedded in metal to protect it from collisions.
If you embed the Reader/Writer in metal, separate it at least 160 mm from any metallic surface to
prevent malfunctions. If the distance between surrounding metal and the Reader/Writer is less than
160 mm, the Reader/Writer communications range will be greatly reduced.
Do not allow the height of the metal to exceed the height of the Reader/Writer.
Mutual Interference of Reader/Writers (for Reference Only)
To prevent malfunctioning due to mutual interference when using more than one Reader/Writer, leave
sufficient space between them as shown in the following diagrams.
If the distance between the Reader/Writers is too short, read / write distance will be reduced.

the Reader/Writer is installed closer than 160 mm to metal
surfaces.
