Impact of secondary fields
Secondary fields in the range from 0 mm to 30% of the limit distance (S
g
) generally always
exist.
They should, however, only be used during configuration in exceptional cases, since the
read/write distances are very limited. Exact details of the secondary field geometry cannot be
given, since these values depend heavily on the operating distance and the application.
When working in dynamic mode, remember that during the transition from the secondary
field to the main field the presence of the tag is lost temporarily. It is therefore advisable to
select a distance > 30 % of S
g
.
