Choice of phototransistor (OPB606) or photodarlington (OPB607) output Unfocused for sensing diffuse surface Low cost plastic housing Filtered (OPB606, OPB607)
OPB606 consists of an infrared Light Emitting Diode (LED) and an NPN silicon phototransistor which are mounted “side-byside” on parallel axes in a black opaque plastic housing.
The OPB607 consists of an infrared Light Emitting Diode (LED) and an NPN silicon photodarlington which are mounted “side -by-side” on parallel axes in a black plastic housing.
The emitting diode and phototransistor of both the OPB606 and OPB607 are encapsulated in a filtering epoxy that reduces ambient light noise.
