*3: Allowable background light level
This is defined as the background light level on the active area at which the photo IC sensitivity* drops by 20 %.
* Sensitivity is the reciprocal of light level, which is constantly detected as a signal.
If background disturbance light strikes a part on the package (other than the active area) of S6841, this may lower the
allowable background light level. Use light-impervious tape to provide light-shielding over the shaded area of the package as
shown below. Light-shielding is unnecessary for S8119.

*4: H→L, L→H propagation delay time
The optical system is adjusted so that the Vo terminal output becomes “Low” voltage when the switch shown in the circuit
below is off. (S6841 is then measured with a signal light input of 1 µW/mm2 illuminance.)

*5: This is the input signal light level for the propagation delay time to stay within specifications.
If the input signal light exceeds this level, the propagation delay time may increase.
