Compact Photoelectric Sensor

SERIES Ver.2

CX-44

When using the BGS function
<When a sensing object is moving right or left to the sensor>

BGS/FGS functions

Stability indicator

This sensor incorporates BGS/FGS functions. Select

either BGS or FGS function depending on the positions of

the background and sensing object.

• Since the 

CX-44□

 use 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

to the setting distance.

BGS function

FGS function

• This function is used when the

sensing object contacts the

background or the sensing object is

glossy, etc.

• Please use the FGS function

together with a conveyor or other

background unit.

Distance adjustment

• When this product is used, be sure to carry

out the distance adjustment.

• 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 right, 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 (purchase 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.

• This function is used when the sensing object is

apart from the background.

Turn the distance adjuster fully counterclockwise 

to the minimum sensing range position.

Turn fully 

2

Place an object at the required distance from the 

sensor, turn the distance adjuster gradually 

clockwise, and find out point 

A  where the sensor 

changes to the detecting condition.

3

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. This 

position is designated as point 

B

. When the 

sensor does not go into the detecting condition 

even if the adjuster is turned fully clockwise, the 

position where the adjuster was fully turned is 

regarded as the point 

B

.

There may be more than 1 turn between point 

A  and 

B

, since this sensor incorporates a  

5-turn adjuster.

4

The optimum position to stably detect objects is 

the center point between  A  and 

B

.

In the state where the sensor detects the 

background, turn the distance adjuster gradually 

counterclockwise, and find out point 

A  where 

the sensor changes to the non-detecting 

condition.

3

Place an object at the required distance from the 

sensor, turn the adjuster counterclockwise further 

until the sensor goes into the non-detecting 

condition again. Once entered, turn the distance 

adjuster backward until the sensor returns to the 

detecting condition. This position is designated 

as point 

B

. When the sensor does not go into 

the non-detecting condition even if the adjuster is 

turned fully counterclockwise, the position where 

the adjuster was fully turned is regarded as the 

point

.

There may be more than 1 turn between point 

A  and

The optimum position to stably detect objects is 

the center point between  A  and 

B

position 

• Follow only steps

 and

. Since the sensing point may

change depending on the sensing object, be sure to

check the operation with the actual sensing object.
