Optimized alignment can be achieved and verified by using the signal strength light bar
located on the back of the sensor. The LEDs on the light bar will illuminate correspond‐
ing to the signal strength light 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 light increases.

Sensing range
Adjust the distance between the sensor and the reflector according to the correspond‐
ing diagram (x = sensing range, y = operating reserve).
NOTE
Note the minimum sensing range between sensor and reflector depending on the
reflector.
