Notes: 1) The model No. with suffix '-Z' is M8 plug-in connecotor type.
(Example) CX-441-P-Z
For the M8 plug-in connector type, use the following mating cables.
CN-24A-C2 (Straight type, 4-core, cable length 2m) CN-24AL-C2 (Elbow type, 4-core, cable length 2m)
CN-24A-C5 (Straight type, 4-core, cable length 5m) CN-24AL-C5 (Elbow type, 4-core, cable length 5m)

2) The adjustable range stands for the maximum sensing range which can be set with the distance adjuster.
3) The detection may be unstable depending on the mounting conditions or the sensing object to be used. In the
state that this product is mounted, be sure to check the operation with the actual sensing object to be used.

MOUNTING

The tightening torque should be 0.5N m or less.
Sensor mounting bracket
MS-CX-3
(Optional)
M3 (length 12mm)
screw with washers
Care must be taken regarding the sensor
mounting direction with respect to the
object's direction of movement.
Sensing Sensing
object object
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 small change in
angle, wrinkles on the object surface, etc.

When a specular body is present below the
sensor, use the sensor by tiling it slightly
upwards to avoid wrong operation.
Specular
face
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-detactable
area right in front of the sensor.

CAUTIONS

Sensing object
Make sure that the power supply is off while
wiring and adjusting.
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.
Never use this product as a sensing 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.
