Installation Guidelines
Reliable Identification Area

The tag should be in the center area of the sensing range:

Identification area diagram
Metal-free Area

The KRH-M30G can be flush-mounted in metal. Allow for a possible reduction in the field data. To avoid any influence on the field data, the distance "R" should be kept to ≥40mm.

Metal-free area diagram

In order to avoid potential conducted interference, it is recommended to use nonmetallic brackets to cut off the transmission path of conducted interference.

Nonmetallic bracket recommendation
Minimum Distance Between Readers

KRH-M30G side by side: to avoid any influence between the readers, the distance "D" should be kept to ≥80mm.

Side by side installation diagram

KRH-M30G face-of-face: to avoid any influence between the readers, the distance "D" should be kept to ≥150mm.
