Features
:
Noncontact switching
Housing opaque material
Printed circuit board mount
0.155" (3.937 mm) width gap, 0.330" (8.382 mm) depth slot
Description:
OPB804
contains an IRLED and phototransistor paired in an opaque plastic housing .
The housing is an opaque grade of injection molded plastic, which minimizes the assembly's sensitivity to visible
and near-infrared radiation. A wide open aperture [0.060" (1.524mm) equivalent] makes it versatile for general
applications.
The output phototransistor turns off when an object opaque to IR (700 nm to 1100 nm) is inserted into the gap
between the emitter and sensor, thereby interrupting the light beam.
