Description of Sensor Parameters
8.2.4 Switch Point 2
You can use this parameter to adjust the switch point 2 in "mm", measured from the ultrasonic
transducer surface of the sensor.
If switch point 1 is set to a farther distance than switch point 2, the two switch points are virtually
inverted within the sensor. This is done to ensure that the set output mode is working as
intended.
8.2.5 Retroreflective Mode Offset
You can use the "Retroreflective mode offset” parameter to change the size of the switching
window in order to adjust the reflector distance defined by switch point 1. The specified offset
works equally in both directions around the reflector distance, i.e., both in the direction of the
sensor as well as away from the sensor. The offset is necessary to avoid output fluctuations
due to changing environmental conditions.

closed
Note
Switch point 2 is not relevant for "Switch point mode" and "Retroreflective mode" output modes
and is therefore hidden in the DTM.
Parameter name Access Value range
Switch point 2 Read/write <Beginning of adjustment
range> ... <End of adjustment
range< [mm]
(See technical data in the sen-
sor datasheet)
Table 8.5
Note
The DTM also accepts values between <Beginning of sensing range> and <Beginning of
adjustment range> as well as values above <End of adjustment range> up to a certain limit.
Values in these ranges are outside of the adjustment range specified by Pepperl+Fuchs; use
them at your own risk.
Note
The "Retroreflective mode offset" parameter is only relevant and visible in the DTM if the output
mode is set to "Retroreflective mode."
Parameter name Access Value range
Retroreflective offset Read/write 1 ... (0.5 x <end of adjustment
range>) [mm]

sor datasheet)
