Specifications of IS1U621L

• Lead Free Status / Rohs Status: Not Compliant

Using the transmitter shown in Fig. 1, the output signal of the light detecting unit is good enough to meet the following items in the standard optical system in Fig. 2.
(1) Linear reception distance characteristics
(2) Sensitivity angle reception distance characteristics
In the above figure, the transmitter should be set so that the output Vout can be 40mV
However, the PD49PI to be used here should be of the short-circuit current I =2.6 A at Ev=100 lx.
(Ev is an illuminance by CIE standard light source A (tungsten lamp).)
Performance
When L=0.2 to 5 m, Ee < 10 lx ( *6) and <= 30 ˚ in the direction X and
the output signal shall meet the electrical characteristics in the attached list. Further, the electrical characteristics shall be met
when L=0.2 to 5 m, Ee < 10 lx (*6) and
When L=0.2 to 8 m, Ee < 10 lx ( *6) and
*6 It refers to detector face illuminance.
