GP1UM287RK0F 技术参数

GP1UM26RK/27RK/28RK/28QK Series

ꢀꢀ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 8.5(7.0)^*7m, ^*5E_V<10 lx and φ=0˚ in Fig.2, the output signal shall meet the electrical characteristics in the attached

list.

2. Sensitivity angle reception distance characteristics

When L=0.2 to 6.0(4.5)^*7m, ^*5E_V<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 4.0(3.0)^*7m, ^*6E_V≤ 300 lx and φ=0˚ in Fig.2, the output signal shall meet the electrical characteristics in the attached

list.

*5 It refers to detector face illuminance

*6 Outer peripheral light source: CIE standard light source A shall be used and placed at 45˚ from perpendicular axis at the detector face center

*7 In case of B.P.F. center frequency: 56.8kHz model

In the above figure, the transmitter should be set so that the output V_{OUT (P-P)}can be 40mV.

However, the PD49PI to be used here should be of the short-circuit current I_SC=2.6µ A at E_V=100 lx.

(E_Vis an illuminance by CIE standard light source A (tungsten lamp).)
