Maximum Sensitivity Setting
• Use the Through-beam Sensor for detection of opaque objects.
• Use the Reflective Sensor for detection of objects with no
background objects.
The threshold will be set to a level slightly higher than the no-light
received by the E3X-NH if the sensitivity is set to maximum for the
detection of objects that completely interrupt light or the incident of
the Sensor is very low.
Reflective Sensor
The number of lit indicators of the incident level indicators will
depend on the incident. The bottom indicator of the threshold indica-
tors is ON.

With/Without-object Teaching
• Ideal for the detection of object surface irregularities or minute
objects.
• Ideal for the detection of objects with background objects
reflecting light irregularly.

2. RUN/ADJ Mode
Reflective Sensor:
The number of lit indicators of the incident level indicators de-
pends on the incident. At the time of manual-tuning, it is pos-
sible to adjust the threshold in six levels. The default thresh-
old is set to 7.
