Choice of photo
transistor (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 photo
transistor 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 photo
transistor of both the OPB606 and OPB607 are encapsulated in a filtering epoxy that reduces ambient light noise.
On both models, the photo
transistors...
