The OPB730 series Reflective Object Sensor that consists of a gallium arsenide infrared emitting diode and an NPN silicon phototransistor. On each sensor, the emitting diode and detector are mounted side-by-side on parallel axes. A black plastic sleeve is attached and filled with encapsulating epoxy to cover the emitter and detector. The OPB730F ("F" versions) have a filtering material added to the epoxy to reduce the effect of ambient light. The package contains an internal barrier which prevents diode emissions from reaching the sensor directly.
- Photodarlington output
- Unfocused for sensing diffuse surface
- Clear encapsulating epoxy
- Filtered to reduce the effect of visible or fluorescent light
