Note: 1. With incident light" denotes the condition whereby
the light reflected by white paper with a reflection
factor of 90% at a sensing distance of 5 mm is
received by the photo IC when the forward current (IF)
of the LED is 20 mA.
4. The value of the response frequency is measured by rotating
the disk as shown below.

3. Hysteresis denotes the difference in forward LED
current value, expressed in percentage, calculated
from the respective forward LED currents when the
photo IC is turned from ON to OFF and when the
photo IC is turned from OFF to ON.
