OPB608C [TT Electronics]

The OPB608 series are reflective object sensors featuring phototransistor output, unfocused design for sensing diffuse surfaces, low-cost plastic housing, enhanced signal-to-noise ratio, and reduced ambient light sensitivity. They include an infrared emitting device (LED or VCSEL) and NPN silicon phototransistor encapsulated in visible filtering epoxy (except OPB608R). Models vary by reflection distance: OPB608A/B/C for 0.050"-0.375", OPB608V for 0.050"-1.200", and OPB608R for visible light (0.050"-0.300"). The VCSEL version supports longer distances while LED versions target near-field applications.
