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

Features:
• Non–contact switching
• Housing opaque material
• Printed circuit board mount
• 0.155” (3.937 mm) width gap, 0.330” (8.382 mm) depth slot

Applications:
• Non-contact object sensing
• Assembly line automation
• Machine automation
• Equipment security
• Machine safety
