Precautions When Mounting This Sensor

• Mount the sensor leaned by 5°-45° so that

lighting should not be reflected 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 figure.

See "Changing Set Value" on Page 48.

Tilt the sensor by 10°-40° to avoid the mirror reflection when a

work is shiny.

• Take caution so that the external lighting (light

from fluorescent light, etc.) is not reflected.
