Circuit Design Considerations
Output of the infrared LED in the photo interrupter
decreases approximately 50% after 100,000 hours.
Recommended load resistance (RL) is 40k ~ 120kΩ
for the illustrated circuit.

LEDs are an integral
part of the switch and
not available separately.
The electrical speci-
fications shown are
determined at a basic
temperature of 25°C.
If the source voltage
exceeds the rated
voltage, a ballast
resistor is required.
