On the CD22 series, the center point of the measurement range is displayed
as “0”.
Distances further away from the sensor than the center point are added to
the value of the center point and are displayed as positive numbers.
Distances closer to the sensor than the center point are subtracted from the
value of the center point and are displayed as negative numbers.

“9999” is displayed when the object is outside the measurement
range or cannot be measured.

FG52 FGS2 teach
Place the object and
execute FGS2 teach to set
the detection range around
the object. (Two thresholds
are set, one before and one
after the object, and the
output turns OFF when the
measurement distance is
within this range.)
1Pt 1-point teach
Teach is executed for one
position: without the object
present (that is, just the
background is detected).
Then, the output turns ON
when the measurement
distance is closer than that
position.

front of the sensor.)

Setting the control output
thresholds
(the switching references)
Use teach mode to set the thresholds used as the references for
switching control output ON and OFF.
To match different applications, the following three modes are available.
• 2-point teach
• 1-point teach
• FGS2 teach
Teach is executed with the
object at two positions: the
near and far points in
relation to the sensor. Then,
output turns ON when the
measurement distance is
between these positions.

The sensor receives light from the background
(such as a white conveyor belt) at all times and
activates when this light is blocked by the
object, so detection is also possible when the
sensor can no longer receive light.
This is the optimal mode for conventionally hard
to detect objects such as thin black objects,
glossy metal, and objects with rough surfaces.
* FGS2 teach requires a stable background
such as a conveyor belt.
