2 CAUTIONS
٨ Make sure to carry out wiring in the power sup-
ply off condition.
٨ Take care that wrong wiring will damage the sensor.
٨ Verify that the supply voltage variation is within
the rating.
٨ 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.
٨ 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.
٨ 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.
٨ 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.
٨ Do not use during the initial transient time (50ms)
after the power supply is switched on.
٨ 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.
٨ Make sure that stress by forcible bend or pulling is
not applied directly to the sensor cable joint.
٨ This sensor is suitable for indoor use only.
٨ 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.
٨ Take care that the sensor does not come in direct contact with
water, oil, grease, or organic solvents, such as, thinner, etc.
٨ When connecting the mating cable to the connector type
sensor, the tightening torque should be 0.4Nm or less.
3 MOUNTING
٨ The tightening torque should be 0.5Nm or less.

٨ Sensitivity adjustment
Step Sensitivity adjuster
Description
Turn the sensitivity adjuster fully counter-
Ԙ clockwise to the minimum sensitivity posi-
tion, MIN.
In the light received condition, turn the sensitivity
ԙ 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
Ԛ
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 .
Optimum position
ԛ
The position at the middle of points
is the optimum sensing position.
and
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.

6 AUTOMATIC INTERFERENCE
PREVENTION FUNCTION
(Excluding thru-beam type sensor)
٨ Retroreflective type sensor and diffuse reflective
type sensor incorporate this function. Up to two
sets of sensor can be mounted closely.
(Thru-beam type sensor does not have this function.)
Close mounting of two sensors
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.

8 RETROREFLECTIVE TYPE SEN-
SOR WITH POLARIZING FILTERS
(CX-491š)
٨ As light is polarized by a transparent film or mem-
brane, CX-491غ may not detect an object covered
or wrapped by transparent film. In that case, take
the following measures.
<Example of sensing objects>
Can wrapped by clear film
Aluminum sheet covered by plastic film
Gold or silver color (glossy) labels or wrapping
paper
<Measures>
Tilt the sensor with respect to the sensing object
upon fitting.
Reduce the sensitivity.
Increase the distance between the sensor and the
sensing object.
9 SLIT MASK (OPTIONAL)
(Exclusively for thru-beam type sensor)
٨ With the slit mask (OS-CX-غ), the sensor can
detect awswmawll.DobajetactS. heet4U.com
However, the sensing range is reduced when
the slit mask is mounted.

10 INTERFERENCE PREVEN-
TION FILTER (OPTIONAL)
(Exclusively for CX-411š)
٨ By mounting the interference prevention filters
(PF-CX4-غ), two sets of the CX-411غ can be
mounted close together.
However, the sensing range is reduced when
the interference prevention filter is mounted.
٨ The filters can be mounted by the same method
as for the slit masks.
٨ 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.
