BGS / FGS functions make even the most challenging settings possible!
The sensor judges that an object is present when light is received
at position A of the light-receiving element (2-segment element).
This is useful if the object and background are far apart. The
distance adjustment method is the same as the conventional
adjustment method for adjustable range reflective type sensors.
Applications
The BGS function is best suited for the following case
BGS (Background suppression) function
■
Detects minute objects unaffected by glossy
background objects. Uses FGS function.

The sensor judges that an object is present when no light is
received at position B of the light-receiving element (2-segment
element). Accordingly, even objects that are glossy can be
sensed. This is useful if the object and background are close
together, or if the object being sensed is glossy.
The FGS function is best suited for the following case
