Width of the transmission window

Determining the width of the transmission window
The following approximation formula can be used for practical applications:
B:
L:
Tracking tolerances
The width of the transmission window (B) is particularly important for the mechanical tracking
tolerance. The formula for the dwell time is valid without restriction when B is observed.
4.1.4

Impact of secondary fields

Secondary fields in the range from 0 to 20 mm always exist.
They should only be applied during planning in exceptional cases, however, 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.
