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
0.3mm
2
, 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.

device for personnel protection.
In case of using sensing devices for personnel
protection, use products which meet standards,
such as OSHA, ANSI or IEC etc., for personnel
protection applicable in each region or country.

Operation mode switch
Description
Light-ON mode is obtained when the opera-
tion mode switch (located on the receiver) is
turned fully clockwise (L side).
Dark-ON mode is obtained when the opera-
tion mode switch (located on the receiver) is
turned fully counterclockwise (D side).

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
Ǿ
0.5mm copper wire.
By mounting interference prevention filters (
PF-CX4-
غ
), two sets of the sensor can be mounted close together. For details, refer
to '
