PRECAUTIONS FOR PROPER USE
CX-41 □
Slit mask (Optional) Interference prevention filter (CX-411□)
• With the slit mask OS-CX-□ , the sensor can detect a
small object.
However, the sensing range is reduced when the slit
mask is mounted.
• By mounting the interference prevention filters PF-CX4-□ ,
two sets of the CX-411 □ can be mounted close together.
However, the sensing range is reduced when the
interference prevention filter is mounted.
• The filters can be mounted by the same method as for
the slit masks.
• Since there are two types of the interference prevention
filter, the two sets of sensors should be fitted with
different types of interference prevention filters, as shown
in the figure below.
The interference prevention does not work even if the
filters are mounted for emitters only, receivers only or the
same model No. of the interference prevention filters are
mounted on both the sets of the sensor.

Mounting Operation mode switch
• Care must be taken regarding the sensor mounting
direction with respect to the object’s direction of movement.
Do not make the
sensor detect an
object in this direction
because it may cause
unstable operation.

• When detecting a specular object (aluminum or copper
foil, etc.) or an object having a glossy surface or coating,
please take care that there are cases when the object
may not be detected due to a change in angle, wrinkles
on the object surface, etc.
• When a specular body is present below the sensor, use the
sensor by tilting it slightly upwards to avoid wrong operation.

Tilt
• If a specular body is present in the background, wrong operation
may be caused due to a small change in the angle of the
background body. In that case, install the sensor at an inclination
and confirm the operation with the actual sensing object.
• Take care that there is a non-detectable area right in front
of the sensor.
Incorrect Correct
• Depending on whether you select the BGS or FGS
function, the output operation changes as follows.

1. Insert the fixing hook into the fixing groove.
2. Then, pressing the slit mask against the main unit, insert
the fixing tab into the fixing groove.
1. Insert a screwdriver into the removing tab.
2. Pull forward while lifting the removing tab.
Operation mode switch Description
Detecting-ON mode is obtained when
the operation mode switch is turned fully
clockwise (L side).
Not detecting-ON is obtained when the
operation mode switch is turned fully
counterclockwise (D side)
Note: Use the flathead screwdriver (purchase separately) to turn
the operation mode switch slowly. Turning with excessive
strength will cause damage to the adjuster.
