Response Time Setting Examples
Setting the response time provides the following advantages.
z
Setting a longer response time
A larger amount of received light increases the sensitivity, which allows for detection at longer distances.
Example) Response time and sensing distance

z
Setting a shorter response time
With a short response time, the product can respond to generate output even when objects block the light
axis for a short period of time.
This is effective in detecting, for example, small objects travelling at high speeds.
Example) Setting a shorter response time to allow for detection of, for example, small objects.

<Long Response time>
If the Response time setting is
longer than the time that light is
received, no output is generated.
<Short Response time>
Output is generated even when
light is received for a short time.
