Make sure to carry out wiring in the power sup-
ply off condition.
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 vicini-
ty of this product, connect the frame ground (F.G.)
terminal of the equipment to an actual ground.
Do not run the wires together with high-voltage
lines or power lines or put them in the same race-
way. This can cause malfunction due to induction.

Take care that the sensor is not directly exposed to fluo-
rescent lamp from a rapid-starter lamp or a high frequency
lighting device, as it may affect the sensing performance.
Do not use during the initial transient time (50ms)
after the power supply is switched on.
Extension up to total 100m, or less, is possible with
0.3mm2, or more, cable. However, in order to re-
duce noise, make the wiring as short as possible.
Make sure that stress by forcible bend or pulling is
not applied directly to the sensor cable joint.
This sensor is suitable for indoor use only.
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.
When connecting the mating cable to the connector type
sensor, the tightening torque should be 0.4N㨯m or less.

The model No. with suffix 'E' shown on the label affixed to the thru-beam type sensor is the emitter, 'D' shown on the label is the receiver.
Thru-beam type sensor emitter: CX-41غE, Thru-beam type sensor receiver: CX-41غD
The model No. of retroreflective type sensor with the suffix '-Y' is the sensor without the RF-230 reflector.
(e.g.) CX-491-Y
The retroreflective type sensor with polarizing filters may not stably detect specular
or glossy objects through transparent film since light is polarized by the transparent
film. For details, refer to ' RETROREFLECTIVE TYPE SENSOR WITH POLAR-
IZING FILTERS'.
The sensing range and the sensing object of the retroreflective type sensor is specified
fot the RF-230 reflector. The sensing range represents the actual sensing range of the
sensor. The sensing ranges itemized in 'A' of the table below may vary depending of the
shape of sensing object. Be sure to check the operation with the actual sensing object.
The sensing range of the diffuse reflective type sensor is specified for white non-
glossy paper (200 200mm) as the object.
The minimum sensing object of the diffuse reflective࡮narrow-view type sensor is
Ǿ0.5mm copper wire.
By mounting interference prevention filters (PF-CX4-غ), two sets of the sensor can be mounted close together. For details, refer
to ' INTERFERENCE PREVENTION FILTER (OPTIONAL)'.

٨With the slit mask (OS-CX-غ), the sensor can
detect a small object.
However, the sensing range is reduced when
the slit mask is mounted.

Insert the fixing hook into the fixing groove.
Then, pressing the slit mask against the main
unit, insert the fixing tab into the fixing groove.

By mounting the interference prevention filters
(PF-CX4-غ), two sets of the CX-411غcan be
mounted close together.
However, the sensing range is reduced when
the interference prevention filter is mounted.
The filters can be mounted by the same method
as for the slit masks.
Since there are two types of the interference
prevention filter, the two sets of sensors should
be fitted with different types of interference pre-
vention filters, as shown in the figure below.
The interference prevention does not work even
if the filters are mounted for emitters only, re-
ceivers only or the same model No. of the inter-
ference prevention filters are mounted on both
the sets of the sensor.

٨Sensitivity adjustment
Note: Use the 'minus' adjusting screwdriver (please arrange sepa-
rately) to turn the adjuster slowly. Turning with excessive
strength will cause damage to the adjuster.
Ԙ
ԙ
Ԛ
ԛ
Turn the sensitivity adjuster fully counter-
clockwise to the minimum sensitivity posi-
tion, MIN.
In the light received condition, turn the sensitivity
adjuster slowly clockwise and confirm the point
where the sensor enters the 'Light' state operation.
In the dark condition, turn the sensitivity ad-
juster further clockwise until the sensor en-
ters the 'Light' state operation and then bring
it back to confirm point where the sensor
just returns to the 'Dark' state operation.
If the sensor does not enter the 'Light' state
operation even when the sensitivity adjuster is
turned fully clockwise, the position is point .
The position at the middle of points and
is the optimum sensing position.

Set the operation mode switch to the Light-ON mode
position (L side).
Placing the emitter
and the receiver face
to face along a straight
line, move the emitter
in the up, down, left
and right directions, in
order to determine the
range of the light re-
ceived condition with
the help of the operation indicator (orange).
Then, set
the emitter at the center of this range.
Similarly, adjust for up, down, left and right angular
movement of the emitter.
Further, perform the angular adjustment for the re-
ceiver also.
Check that the stability indicator (green) lights up.
Choose the operation mode, Light-ON or Dark-ON, as
per your requirement, with the operation mode switch.

Note: If two diffuse reflective type sensor are mounted facing each
other, they should be angled so as not to receive the beam
from the opposing sensor or to detect its front face.

sets of sensor can be mounted closely.
