6-1. Response Time
Longer response times lead to more stable detection.

6-2. Output Logic
Select N.O. or N.C. for the output logic. For details, see "4 Detection Mode" (page 4).
6-3. Output Mode
„ Standard [Standard]
The output is activated according to the detecting distance. For details, see "4 Detection
Mode" (page 4).
„ Window [Window]
The output is activated according to the detecting distance. For details, see " 4-3.
Window Mode" (page 5).
„ Stability [Stability]
This function can be used to check whether there has been a decrease in the amount of
light received due to problems such as dirt on the detected surface.
z When the I/O selection is [Out1 + Out2]
Output is activated if the amount of light received falls below the threshold (fixed value)
during the observation period.
Example) Chart during DATUM mode
„ Error [Error]
Output is activated when an error occurs. When the error is cleared, the output is also
automatically reset. For causes of errors, see
" Error Display" (page 10).
6-4. Timer
This function can be used to delay the timing with which the sensor output is switched.
• Off delay [Off-delay]
• On delay [On-delay]
• One shot [One shot]
