FGS / BGS functions make even severe settings possible!
Refer to ‘BGS / FGS functions’ (p.9) of ‘PRECAUTION FOR PROPER USE’ for details on the operation of the FGS / BGS functions.
The FGS function is ideal to use in the following cases
When the object and the background are close together
FGS
FGS (Foreground suppression) 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 object that are glossy can be sensed. This is
useful if the object and background are close together, or of the
object being sensed is glossy.

APPLICATIONS
Sensing sweets on a conveyor
Sensing objects on nearby lines
Senses two thin objects overlapping
Even objects such as thin chocolates or
biscuits can be sensed stably without being
affected by the conveyor.
Stable sensing is obtained even when two
production lines are in close proximity.
Two overlapping thin objects can be sensed
regardless of the material or color.

• Depends on a selection of either BGS or FGS function, the
output operation changes as follows.
Sensing range
• Care must be taken regarding the sensor mounting direction with
respect to the object’s direction of movement.
Setting distance
Do not make the
sensor detect an

Sensing object
• When detecting a specular object (aluminum or copper foil, etc.)
or an object having a glossy surface or coating, please take care
that there are cases when the object may not be detected due to
a change in angle, wrinkles on the object surface, etc.
• When a specular body is present below the sensor, use the
sensor by tilting it slightly upwards to avoid wrong operation.

BGS / FGS functions
Specular
face
• This sensor incorporates BGS / FGS functions. Select either BGS
or FGS function depending on the positions of the background
and sensing object.
BGS function
• This function is used when the sensing object is apart from the
background.
Sensing
object
Background
Tilt
• If a specular body is present in the background, wrong operation
may be caused due to a small change in the angle of the
background body. In that case, install the sensor at an inclination
and confirm the operation with the actual sensing object.
• Take care that there is a non-detectable area right in front of the
sensor.
Stability indicator
• Since the CX-400 series uses a 2-segment photodiode as its
receiving element, and sensing is done based on the difference
in the incident beam angle of the reflected beam from the sensing
object, the output and the operation indicator (orange) operate
according to the object distance.
Further, the stability indicator (green) shows the margin of the
setting distance.

PRECAUTIONS FOR PROPER USE
Distance adjustment
Wiring
• Since the distance adjuster of this sensor is a 5-turn
adjuster, when the point A and B is adjusted as
explained in the table below, there may be more
than 1 turn between the point A and B. Therefore,
make sure to remember the turns of both points to
find the optimum position.
• Be sure to wire the sensing mode selection input
(Pink / 2) before distance adjustment. If the wiring is
done after the distance adjustment, the sensing
area is changed.
• Turn the distance adjuster gradually and lightly with a ‘minus’
screwdriver (please arrange separately). In order to protect itself,
the distance adjuster idles if turned fully.
If the adjuster is idled when distance adjustment is done, carry out
the adjustment again.
In case BGS function is used
Step
Description

Turn the distance adjuster fully counterclockwise to
the minimum sensing range position. (40 mm

CX-441)
Distance adjuster
Others
• Do not use during the initial transient time (50 ms) after the
power supply is switched on.
• Take care that the sensor is not directly exposed to fluorescent
light from a rapid-starter lamp or a high frequency lighting device,
as it may affect the sensing performance.
• This sensor is suitable for indoor use only.
• Its distance adjuster is mechanically operated. Avoid drops or
other shocks.
• Do not use this sensor in places having excessive vapor, dust,
etc., or where it may come in direct contact with water, or
corrosive gas.
• Take care that the sensor does not come in direct contact with
water, oil, grease or organic solvents, such as, thinner, etc.
• This sensor cannot be used in an environment containing
inflammable or explosive gases.
• Never disassemble or modify the sensor.
Turn fully
Place an object at the required distance from the
sensor, turn the distance adjuster gradually
2 clockwise, and find out point A where the sensor
changes to the detecting condition.
3
• Make sure that the power supply is off while wiring and
adjusting.
• Take care that wrong wiring will damage the sensor.
• Verify that the supply voltage variation is within the rating.
• If power is supplied from a commercial switching regulator,
ensure that the frame ground (F.G.) terminal of the power supply
is connected to an actual ground.
• In case noise generating equipment (switching regulator, inverter
motor, etc.) is used in the vicinity of this product, connect the
frame ground (F.G.) terminal of the equipment to an actual
ground.
• Extension up to total 100 m 328.084 ft is possible with 0.3 mm2,
or more, cable.
However, in order to reduce noise, make the wiring as short as
possible.
• Do not run the wires together with high-voltage lines or power
lines or put them in the same raceway.
This can cause malfunction due to induction.
Remove the object, turn the adjuster clockwise further until the
sensor goes into the detecting state again. Once it has entered,
turn the distance adjuster backward until the sensor returns to
the non-detecting condition. That position is designated as point
B. When the sensor does not go into the detecting condition
even if the adjuster is fully turned clockwise, the position where
the adjuster was fully turned is regarded as the point B.
There may be more than 1 turn between the point A
and B, since this sensor incorporates 5-turn adjuster.
Optimum
