The circuit constant is a example. It is difference from mounting equipment. Please select it by your mounting equipment.
Please be carefully not to apply exceeding the absolute maximum ratings of applying voltage and continuous high voltage spike
3. If the surface of detector is smeared with dust or dirt,it may cause faulty operation.Caution shall be taken t avoid this.
And do not touch the detector surface. IF the surface was smeared,wipe it clesan with soft cloth.
4. The shield case shall be grounded on the PCB pattern.
(that shield case and GND pin are not connected.)
5. The shield case is fixed temporarith When handring the product(including mounting),please be careful not to forse

・ON signal time TON：250μs or more.
In case the signal format of total duty and/or ON/OFF signal time dosen`t meet the conditions noted above, there is a
case that reception distance much reduces or output dose not appear.

2. Use the light emitting unit (remote control transmitter), in consideration of performance, characteristics, operating conditions of
light emitting device and the characteristics of the light detecting unit.
If cleaning the product is needed after the soldering,the cleaning with alcohol is recommended.
When cleaning the product,please extremely check the acceptance surfase and the extrenal appearance
6. Please don't push the detecting side(photodiode)from external side.
7. In order to prevent electrostatic discharge of integrand circuit,human body and solding iron,etc.shall be grounded.
