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.

· 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).
