Reflective Object Sensor
OPB606A, OPB606B, OPB606C
OPB607A, OPB607B, OPB607C
Features:
• Choice of phototransistor (OPB606) or photodarlington
(OPB607) output
• Unfocused for sensing diffuse surface
• Low cost plastic housing
• Filtered (OPB606, OPB607)
Description:
OPB606 consists of an infrared Light Emitting Diode (LED) and an NPN silicon phototransistor which are
mounted “side-by-side” 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. On both models, the phototransistors respond to radiation from the emitter only
when a reflective object passes within the field of view.
Custom electrical, wire and cabling and connectors are available. Contact your local representative or OPTEK for
more information.

To avoid stress cracking, we suggest using ND Industries’ Vibra-Tite for thread-locking.
Vibra-Tite evaporates fast without causing structural failure in OPTEK’s molded plastics.
