GP1U58X Series

s Performance

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

When L= 0.2 to 8m, Ee< 10 lx and φ = 0˚ in Fig. 2, the output signal shall meet the electrical

characteristcs in the attached list.

( 2) Sensitivity angle reception distance characteristics

When L= 0.2 to 6m, Ee< 10 lx and φ <= 30˚ in Fig. 2, the output signal shall meet the electrical

characteristics in the attached list.

( 3) Anti outer peripheral light reception distance characteristics

When L= 0.2 to 4m, Ee<= 300 lx and φ = 0˚ in Fig. 2, the output signal shall meet the electrical

characteristics in the attached list.

In the above figure, the transmitter should be set so that the output Vout can be 40mVPP .

However, the PD49PI to be used here should be of the short-circuit current ISC= 2.6 µ A at E V=

100 lx.
