8.3.1.1
Distance range
The “Distance range” function can be used to define an evaluation range in which the
device measures object distances. All surrounding ranges are blanked. A typical appli‐
cation is the blanking of a transparent protective screen fitted between the object and
the device.
During configuration, note that the application must take into account a tolerance
range of 15 mm outside the set limits of the distance range. Reliable blanking and
detection of objects cannot be guaranteed within this tolerance range.

Near limit and far limit
The
near limit
and
far limit
values are the distances in mm which define the limits of the
evaluation range.
NOTE
As there are limited discretization steps, the device transfers the limit values entered to
the next possible distance values (mm). The recalculated value is adopted by the device
and is also shown on the display.
Simple configuration of the distance range is also possible via the SOPAS ET software,
see "Operation via SOPAS ET", page 59
