Note:
1. 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.
2. The value of the response frequency is measured by
rotating the disk as shown below. (P.P.S = pulse/s)
3. The following illustrations show the definition of response
delay time.
