OPB730

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
