The Influence Of Requirements Of Use On Transmission Distance (Reference Values); Influence Of Metal Objects Surroundings And Metal Objects Behind The Device - Omron V700 series Operation Manual

6. The Influence of Requirements of Use on Transmission
Distance (Reference Values)
When using the Reader Writer, transmission distance varies in accordance with the
requirements of use (the existence / non-existence of metal objects in the vicinity, the use
/non-use of multiple Reader Writer, power voltage value, etc.). This section indicates how
such requirements and changes in them affect communication distance. Please use the
following figures for your reference. Note that all values indicated in this section are
reference.
6.1 Influence of Metal Objects Surroundings and Metal Objects Behind the
Device
When metal objects are around or behind the Reader Writer, transmission
distance deteriorates. Please take note of the distance between the metal objects
and the Reader Writer as per below when using the Reader Writer.
When the metal object is steel, the relationship between the distance of the metal
objects around and behind the Model V700-HMC71 from the device and the
transmission distance (read / write) is indicated below. The following values were
obtained by using Tags Model V700-D13P31 / Model V700-D13P21 with an axis
variation of +- 0 mm.
