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-

SX4081.
