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

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 sensor 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 narrowview 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)’.

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.
䢇 In case noise generating equipment (switching

terminal of the equipment to an actual ground.
䢇 Do not run the wires together with high-voltage
lines or power lines or put them in the same raceway. This can cause malfunction due to induction.

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

q Set the operation mode switch to the Light-ON
mode position (L side).
w 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 received condition with
the help of the operation indicator (orange). Then,
set the emitter at the center of this range.
e Similarly, adjust for up, down, left and right angu-
lar movement of the emitter.
r Further, perform the angular adjustment for the
receiver also.

Turn the sensitivity adjuster fully
counterclockwise to the minimum
sensitivity position, MIN.
In the light received condition, turn the
sensitivity adjuster slowly clockwise
and confirm the point A where the sensor enters the ‘Light’ state operation.
In the dark condition, turn the sensitivity adjuster further clockwise until
the sensor enters the ‘Light’ state operation and then bring it back to confirm point B 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

B.
The position at the middle of points
A and B is the optimum sensing
position.
