[S7] Detection
4-6-3 [S7] - [D3] APC
This function automatically adjusts the power input to the emitter LED.
When the emitter power becomes unstable due to the ambient temperature or aging deterioration of the
LED, this function stabilizes detection by maintaining the emitter power.
MEMO
• This function is effective when the difference in the received light amounts with and without an object is small.
• Use of this function for a long time will slightly shorten the service life of the LED.

The power to the emitter changes due to
the temperature change, making the
received light amount change.
The power to the emitter is adjusted
according to the temperature change to
maintain a constant received light amount.

On (default value) Enables the APC function.
Off The APC function is not used.
4-6-4 [S7] - [D4] ASC
This function monitors the received light amount when no object is present, and correspondingly adjusts the
threshold.
Through the use of product, the received light amount may decrease due to factors such as contamination of
the optical system, eventually resulting in errors by falling below the threshold. Enabling the ASC function
lowers the threshold to match decreases in the received light amount, allowing for long-term stable detection.
This function is especially effective when detecting transparent objects.
