EE-SX3340/EE-SX4340
*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-SX4340.
