Precautions of Use
(1) Care must be taken to avoid bending leads.
(2) Do not apply any force or mechanical stress onto the leads or plastic part during soldering.
(3) Confirm reliability in terms of devices, because it sometimes acts be wrong by the ingredient of the ripple noise of the

Transmitter
The Transmitter shall be defined by adjusting the output of transmitter to make Vo=400mVp-p according to the burst wave
shown in Fig. 1 and measurement condition shown in Fig.2. In addition infrared LED used in the transmitter is set to

Please design the ripple voltage of the power supply line below 1mVp-p.
Please attach the RC filter (R=100 , C=22 F) for the power supply lines.
