WZ
Version
The OPB703, OPB704 and OPB705 consist of an Infrared (890nm) Light Emiꢀng Diode (LED) and a NPN silicon Phototransistor,
mounted side-by-side on converging opꢁcal axes in a black plasꢁc housing and are designed for PCBoard mounꢁng. The
OPB703WZ, OPB704WZ, OPB705WZ and OPB70BWZ are designed for remote mounꢁng uꢁlizing interconnect wires of UL
approved 26 AWG, 24” (61.0cm) minimum length, stripped and ꢁnned.
The OPB70AWZ consists of an Infrared (890nm) Light Emiꢀng Diode (LED) and a NPN silicon Photodarlington, mounted side-by-
side on converging opꢁcal axes in a black plasꢁc housing and is designed for remote mounꢁng uꢁlizing interconnect wires of UL
approved 26 AWG, 24” (61.0cm) minimum length, stripped and ꢁnned.
The OPB70CWZ through OPB70FWZ consist of a Visible (Red 640nm) Light Emiꢀng Diode (LED) and a NPN silicon Phototransistor
or Rbe Phototransistor, mounted side-by-side on converging opꢁcal axes in a black plasꢁc housing and are designed for remote
mounꢁng uꢁlizing interconnect wires of UL approved 26 AWG, 24” (61.0cm) minimum length, stripped and ꢁnned.
Various lens opꢁons are available: No lens for the (OPB703, OPB703WZ), blue window for dust protecꢁon for the (OPB704,
OPB704WZ, OPB70BWZ, OPB70HWZ) and aperture lens for improved resoluꢁon for the (OPB705, OPB705WZ, OPB70AWZ,
OPB70CWZ, OPB70DWZ). The OPB704G and OPB704GWZ offers excellent protecꢁon for dirty environments.
The phototransistor responds to illuminaꢁon from the emiꢂer when a reflecꢁve object passes within the field of view centered
typically at 0.15” (3.8 mm).
