Selecting the appropriate resolution :
Choose between HIGH and NORMAL resolution by changing polarity
of the
voltage supply. In the NORMAL mode weaker signals are also
evaluated.
The sensor’s sensing range is extended (60 cm) and the sensor can be
used in
difficult environmental conditions. If high speed detection is
required, select HIGH
resolution. The sensing range is reduced to 30 cm and compensation
of influences
due to deposits are not compensated to the same degree but in this
mode the
response time is 1 ms instead of 2 ms (NORMAL resolution).
The minimum target sizes and minimum distances between two adjacent
objects
are shown in the table below.
