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 in turned from ON to OFF and when the
photo IC in turned from OFF to ON.
2. The value of the response frequency is measured
by rotating the disk as shown below.
3. The following illustrations show the definition of response
delay time. The value in the parentheses applies to the
EE-SX4161.
