Installation interval
When mounting 2 or more sets of thru-beam type sensors side by side, they
must be separated by a certain interval to prevent interference.

Retroreflective type sensor

Make sure to mount the sensor and the reflector at least 0.1mm
apart.
1. Set the operation mode switch to the Light-ON mode position (L side).
2. Placing the sensor and the reflector face to face along a straight line.
Move the reflector up, down, left and right to determine where light is
received the help of the operation indicator (orange). Set the reflector in
the middle of this area.
3. Adjust the angle of the reflector by twisting it up, down, left and right.
4. In a similar manner, adjust the angle of the sensor.
5. Check that the stability indicator (green) lights up.
6. Choose the deisred operation mode, Light-ON or Dark-ON, with the
operation mode switch.

Reflector
When sensing glossy objects with CX-493 or transparent objects
with CX-48

These measures are not necessary for the retroreflective type with
polarizing filters CX-491.
1. Make sure the parallel distance (L) between the sensor and the object
being sensed is great enough. Otherwise light might be reflected and
erroneously detected by the sensor.
2. Install the sensor at an angle of 10 to 30° to the object being sensed.
(L)
When sensing transparent objects with CX-48
For optimum sensing, the distance should be the same between the

transparent object being sensed and the sensor and the transparent
(ℓ)

object and the reflector. Otherwise, sensing may be unstable.
CX-48
 When the sensor detects an irregular plastic receptacle or glass bottle,
the received light intensity may differ with the sensing position or
direction. Adjust the sensitivity after confirming the stable sensing
condition by turning the sensing object, etc.
 If the object is a transparent cylinder, feed it in a standing, not a lying,
position.
