2 Sensing range
Note application conditions: Adjust distance between sender and receiver with the associ‐
ated diagram [see figure
If several through-beam photoelectric sensors which are installed next to one another are
to be used, we recommend swapping the sender/receiver arrangement at every second
through-beam photoelectric sensor and ensuring that there is sufficient distance between
the through-beam photoelectric sensors. By doing this, mutual interference can be pre‐
vented [see figure 1].

3 Sensitivity setting
Sensor with potentiometer: open the sensor cover and protective hood, make sure that no
dirt has gotten into the device.
The sensitivity is adjusted with the potentiometer (type: without stop). Clockwise rotation:
operating reserve increased; counterclockwise rotation: operating reserve reduced. We
recommend setting the potentiometer to "Maximum".
The sensor is adjusted and ready for operation.
4 Time function setting
WS/WE34xx4x: no time delay, t1 = time delay, t2 = time delay; for -R: 0 = relay deactivated,
1 = relay active. Time delay selector switch can be set on the device according to the
following graphic.
Time stages: 0.5 ... 10 s can be adjusted.
