PRECAUTIONS FOR SAFE USE
• Do not disassemble nor modify the device.
Otherwise, it may cause a re or an electric shock.
• Continuing to use the device under abnormal
conditions, such as those with abnormal smell or
smoke, may cause a re or an electric shock. In
such cases, immediately pull out the power plug and
conrm that the abnormal condition is removed, and
then contact us or our sales representative. Never
repair the device by yourself since it is dangerous.
• Do not use the device by a power voltage outside
12-24 V DC. It may cause a re or an electric shock.

generated
• Place involving corrosive or ammable gases
• Place where the device is subject to water, oil,
and /or chemical splashes
• Place with direct vibration and impact
• Do not handle electric cables as follows. Otherwise,
cables may be damaged, resulting in a re or an
electric shock.
• Damage • Torture • Pull
• Twist • Bundle, • Put heavy stuff
• Do not touch the device or its cable with wet hand.
Otherwise, it may cause an electric shock.

• Do not insert any improper cable or metal into
electrical terminals. It may result in short-circuiting
inside the device, causing a re, an electric shock,
and / or a failure.
• Do not drop this device nor give any strong impact
on it. It may result in personal injury, if it falls on your
foot, or a device failure.
• Securely mount this device. This device may
fall off due to insufcient mounting or unstable
mounting position, resulting in personal injury or
an accident.
• Wipe off the dirt on this device with a soft, dry
cloth or a rmly squeezed cloth wet with diluted
neutral detergent.
• Please note that there may be dead pixels or
bright pixels with the LCD screen although it
has been produced with a super-high precision
technology.

Precautions When Mounting This Sensor
• Mount the sensor leaned by 5°-45° so that
lighting should not be reected by a work.
5°-45°
Work
• Detection may become successful by changing
the setting even if a detected image is
displayed as shown in the right gure.
See "Changing Set Value" on Page 48.
Tilt the sensor by 10°-40° to avoid the mirror reection when a
work is shiny.
• Take caution so that the external lighting (light
from uorescent light, etc.) is not reected.

• The work imaging condition changes depending on the distance
between the sensor and a work and the tilted angle of the sensor.
When detecting a slight difference in shape, smear, or aw of a work,
furnish more stable bracket for this sensor and design the machine so
that attering of works is reduced as much as possible.
• Refer to the standard object distance of each model as to the distance
between this sensor and a work.
See "Specications" on Page 65.
If the object distance is too near, the sensor becomes out of focus,
causing a irregular lighting, while it is too far, the sensor is likely to
receive the inuence of the turbulence light since the light does not
reach the work.
See "Correction of Brightness Irregularity" on Page 46.
• When a work moving very fast is going to be detected, the shutter time
(brightness) has to be shortened. In such a case, make the distance
between the sensor and a work closer or add additional external
lighting since quantity of light becomes insufcient with only the light
built in this sensor.
See "Options" in Page 11.
• The shutters of the image sensor of this device open in sequence from
the right to the left in the screen. Because of this reason, the work
traveling from the right to the left is displayed wider and the one
traveling opposite is displayed narrower.
In order to detect a slight difference in shape, slow down the travel
speed of a work.
• Please note that there may be dead pixels (pixels that cannot receive
light correctly) with this image sensor. Although dead pixels may
not detect or detect incorrectly, they will not be any problem on the
practical use since they are very few.
