This function delays the control output of this product.

Selectable Options
You can select the timer setting from the following six timer modes.
Selectable option Function description Setting value
Not used Do not use the timer function. (Default value) —
On delay The output is delayed by the set time after the on judgment. 1 to 30,000 ms (default
value: 1 ms)
Off delay The output is delayed by the set time after the off judgment.
On/off delay The On delay and Off delay timers are activated.
Pulse output Output turns on for the set period of time after the on judgment.
On delay pulse The On delay and Pulse output timers are activated.
„
On delay
After the on judgment, output is not generated until the set timer duration elapses.
Even if there are detections shorter than the timer duration, no output is generated, preventing the output of
fluctuating detection results due to, for example, noise.
„
Off delay
This function prevents the output from turning off immediately after detection changes to off, as the output is
held for the set timer duration.
This makes it possible to extend the output duration by the set time, even when the detection time is short.
This allows for input to input equipment that cannot receive short input signals.
Example) On delay and Off delay timing chart
The detection and output turning on/off differs in the above diagram.
<On delay operation>
When detection is made for a duration that exceeds the On delay time, the output turns on. Therefore, even
if detection is judged momentarily, as indicated by A, output is not generated.
This prevents chattering caused by short noise.
