Note)
· The photo IC diode has a specific polarity (anode/cathode). Be careful to make the correct connection.
· The photo IC diode must be reverse-biased so that a positive potential is applied to the cathode.
· Set load resistance R by taking the latter circuit into account.
· To eliminate high-frequency components, we recommend placing a load capacitance CL in parallel with load resistance RL as
a low-pass filter.

Cut-off frequency fc = _2πCLRL
· Before using, check whether noise is present in the location where this product is used. Take measures to prevent noise as
needed, for example, by shielding the cable or adding a capacitor (about 0.1 µF between the anode and cathode of the photo
IC diode).
