CAUTIONS
Make sure to carry out wiring in the power supply
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 regu-
lator, 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 vicin-
ity 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.
Notes:1) The model No. with suffix ‘-J is the M12 pigtailed type, -Z is the M8 connector type.
(e.g.) M12 pigtailed type: CX-411-J, M8 connector type: CX-411-Z
Use the connection cables as shown below. (Two sets are required for the thru-beam type sensor.)
CX-400 Series
Amplifier Built-in
2) 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 m RETROREFLECTIVE TYPE SENSOR WITH
POLARIZING FILTERS’.
3) The sensing range and the sensing object for the retroreflective type sen-
sor is specified for the RF-230 reflector.
Further, make sure to mount the sensor and the reflector 0.1m, or more,
away from each other.
4) The sensing range of the diffuse reflective type sensor and the narrow-
view reflective type sensor is specified for white non-glossy paper
(200 × 200mm) as the object.
5) By mounting interference prevention filters (PF-CX4-
M
), two sets of the
sensor can be mounted close together.
For details, refer to .INTERFERENCE PREVENTION FILTER (OPTIONAL)’.

Do not use during the initial transient time (50ms)
after the power supply is switched on.

, 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.
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.
The model No. of retroreflective type sensor with the suffix -Y is the sensor without the RF-230 reflector.

Never use this product as a sens-
ing device for personnel protection.
In case of using sensing devices
for personnel protection, use prod-
ucts which meet standards, such
as OSHA, ANSI or IEC etc., for per-
sonnel protection applicable in
each region or country.
WARNING
Light-ON mode is obtained when
the operation mode switch (located
on the receiver) is turned fully clock-
wise (L side).
Dark-ON mode is obtained when the
operation mode switch (located on
the receiver) is turned fully counter-
clockwise (D side).
