1. When this infrared remote control detecting unit shall be adopted for wireless remote control, please use it with the signal format of
2. Use the light emitting unit (remote control transmitter), in consideration of performance, characteristics, operating conditions of
3. Pay attention to a malfunction of the light detecting unit when the surface is stained with dust and refuse.
4. The shield case should be grounded on PCB pattern.
5. Do not apply unnecessary force to the terminal and the case.
6. Do not push the light detector surface (photodiode) from outside.
7. To avoid the electrostatic breakdown of IC, handle the unit under the condition of grounding with human body, soldering iron, etc.
8. Do not use hole and groove set in the case of the light detecting unit for other purposes, since they are required to maintain the
9. External Circuit Examples (Mount the outer parts as near the unit as possible).
transmitter, which total duty ratio D
(Pulse width of the presence of modulated IR) should be 250(200:In case of B.P.F. center frequency:56.8kHz model) s or more. In
case that the signal format of total duty and ON signal time is out of above conditions, there is a case that reception distance is
much reduced or output is not appeared.
light emitting device and the characteristics of the light detecting unit.
Care must be taken not to touch the light detector surface.
If it should be dirty, wipe off such dust and refuse with soft cloth so as to prevent scratch. In case some solvents are required, use
methyl alcohol, ethyl alcohol or isopropyl alcohol only.
Also, protect the light detecting unit against flux and others, since their deposition on the unit inside causes reduction of the
function, fading of markings such as the part number.
(The area across the shield case and the GND terminal is internally conductive in some cases and non-conductive in some other
cases.)

In setting R
The circuit constant is a example. It is difference from mounting equipment. Please select it by your mounting equipment. This
device has a transistor as protection element between V
Please be carefully not to apply exceeding the absolute maximum ratings of applying voltage and continuous high voltage spike
noise because there is cases that transistor will be short by secondary breakdown generally.
In order to do difficultly, Please add CR filter (47 (1/10W), 10 F or more) such as external circuit example above near V
