Infra red light: Align the sender with the receiver. Select the position so that the infrared
light (not visible) hits the receiver. Use the signal strength light bar on the rear of the
sensor to determine the correct alignment. See
have a clear view of the receiver, with no object in the path of the beam. You must
ensure that the optical openings (front screen) of the sensors are completely clear.
Optimized alignment can be achieved and verified by using the signal strength light
bar located on the back cover of the sensor. The LEDs on the light bar will illuminate
corresponding to the strength of signal received by the sensor. When no or only red
LEDs are illuminated, the sensor is receiving no or too little signal to switch the output.
The first yellow LED will illuminate at the minimum switching threshold and the green
LEDs will continue to illuminate as the received signal increases [see

Sensing range
Observe the application conditions: Adjust the distance between the sender and the
receiver according to the corresponding diagram [see
operating reserve).
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 dis‐
tance between the through-beam photoelectric sensors. By doing this, mutual interfer‐
ence can be prevented [see
