Note: 1. Refer to the temperature rating chart if the ambient temperature exceeds 25C.
2. If you mount the Sensor with screws, use M3 screws, spring
washers, and flat washers and use a tightening torque of 0.5
N·m max.
3. You should use the product in the condition without any
stress on the cable.

3. The following illustrations show the definition of response
delay time. The value in the parentheses applies to the EESX4088.
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.
