Description:
The OPB703, OPB704 and OPB705 consist of an Infrared (890nm) Light Emitting Diode (LED) and a NPN silicon Phototransistor, mounted side-by-side on converging optical axes in a black plastic housing and are designed for PCBoard mounting. The OPB703WZ, OPB704WZ, OPB705WZ and OPB70BWZ are designed for remote mounting utilizing interconnect wires of UL approved 26 AWG, 24” (61.0cm) minimum length, stripped and tinned.
The OPB70AWZ consist of an Infrared (890nm) Light Emitting Diode (LED) and a NPN silicon Photodarlington, mounted side-by-side on converging optical axes in a black plastic housing and are designed for remote mounting utilizing interconnect wires of UL approved 26 AWG, 24” (61.0cm) minimum length, stripped and tinned.
The OPB70CWZ through OPB70FWZ consist of an Visible (Red 640nm) Light Emitting Diode (LED) and a NPN silicon Phototransistor or Rbe Phototransistor, mounted side-by-side on converging optical axes in a black plastic housing and are designed for remote mounting utilizing interconnect wires of UL approved 26 AWG, 24” (61.0cm) minimum length, stripped and tinned.
Various lens options are available: No lens for the (OPB703, OPB703WZ), blue window for dust protection for the (OPB704, OPB704WZ, OPB70BWZ) and Aperture lens for improved resolution for the (OPB705, OPB705WZ, OPB70AWZ, OPB70CWZ and OPB70DWZ).
The phototransistor responds to illumination from the emitter when a reflective object passes within the field of view centered typically at 0.15” (3.8 mm).
