Safety Precautions
WARNING
Maintaining Smooth Detection
• The Sensor may not function properly if the sensing object
has a metallic or shiny surface. If this is the case, make sure
that the Sensor is not perpendicular to the sensing object.
This will help to correctly identify colors (especially for E3SVS5).
This product is not designed or rated for
ensuring safety of persons. Do not use it for
such purpose.
Precautions for Correct Use
Do not use the product in atmospheres or environments that
exceed product ratings.
Glossy
surface
● Mounting
Marks on Transparent Sheets
• To detect marks on transparent sheets, place a reflective
object underneath where the mark passes.
Sensing object
5° to 15°
Create an
angle.
