Influence of Surrounding Metal on Reader/Writer
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 80 mm from any metallic surface to
prevent malfunctions. If the distance between surrounding metal and the Reader/Writer is less than 80
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.
30 mm max.
Metallic material
Provide a Cable bending radius of 40 mm or more.
The communications range will be reduced significantly
if the Reader/Writer is installed closer than 80 mm to
metal surfaces.
Mutual Interference of Reader/Writers
To prevent malfunctioning due to mutual interference when using more than one Reader/Writer, leave
sufficient space between them as given in the following table.
If the distance between the Reader/Writers is too short, the read/write distances will be reduced.
