NOTICE
It must be noted that the overall sensing range of the antennas is greater than the sensing
range to be configured. This means there can be label alignments where even labels
outside the sensing range will be detected. Labels aligned in parallel with the antennas, for
example, can also be detected at larger distances beside or outside the antenna range.
For this reason, goods with labels must not be stored within a distance of up to 0.5 m from
the installation. If this cannot be complied with, the antennas must be shielded.
To achieve three-dimensional detection of the labels in the sensing range, the following
requirements must be met:
 The gate width must be less than or equal to 800 mm.
 The antenna size of the labels must be at least the size of an ISO card (85 mm x 54
 The distance from label to label must be greater than 100 mm. The distance from label
 There must be no more than 16 labels within the sensing range of the antennas at the
 The maximum speed of the labels must not exceed 1 m/s. (This depends on the number
 To the front and sides of the antenna, there must be a distance of more than 150 mm to
 There must be no interference to the write/read device from other electrical equipment in
