With/Without-object Teaching, No-object Teaching, Maximum Sensitivity Setting
Refer to the following table to select the most suitable sensitivity setting method.
Sensitivity setting method Maximum sensitivity setting
No-object teaching
With/Without-object teaching
Typical application
Detection of the existence of
objects that interrupt light
perfectly
Detection of objects with no
background objects
If teaching is impossible by
stopping the movement of
sensing objects
To detect bright or dark objects
by teaching only with background
objects
Detection of a slight difference in
reflection
Color discrimination
Background objects with
unstable reflection
Detection of object surface
irregularities
Elimination of background object influence
Note: 1. None of the four channels has any output when the E3X-NM (four channels) is in teaching mode (i.e., all the four channels will be in
teaching mode).
2. If the set distance is very short (i.e., 0 to 12 mm for the E32-TC200 and 0 to 4 mm for the E32-DC200), no-object teaching is not
possible due to excessive light, in which case, perform with/without-object teaching.
3. In principle, use the E3X-NM (four channels) for the close connection of a maximum of four Fiber Units. When closely connecting
two to three Fiber Units to more than one E3X-NT (one channel), perform with/without-object teaching, in which case teaching must
be performed on a single E3X-NT at a time. Therefore, turn on only the E3X-NT on which teaching is performed. If all the E3X-NTs
are turned on, interrupt the emitters of the Fiber Units on which teaching is not performed.
