Description:
The OPB703, OPB704 and OPB705 consist of an Infrared (890nm) Light Eming Diode (LED) and a NPN silicon Phototransistor,
mounted side-by-side on converging opcal axes in a black plasc housing and are designed for PCBoard mounng. The
OPB703WZ, OPB704WZ, OPB705WZ and OPB70BWZ are designed for remote mounng ulizing interconnect wires of UL
approved 26 AWG, 24” (61.0cm) minimum length, stripped and nned.
The OPB70AWZ consists of an Infrared (890nm) Light Eming Diode (LED) and a NPN silicon Photodarlington, mounted side-by-
side on converging opcal axes in a black plasc housing and is designed for remote mounng ulizing 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 Eming Diode (LED) and a NPN silicon Phototransistor
or Rbe Phototransistor, mounted side-by-side on converging opcal axes in a black plasc housing and are designed for remote
mounng ulizing interconnect wires of UL approved 26 AWG, 24” (61.0cm) minimum length, stripped and nned.
Various lens opons are available: No lens for the (OPB703, OPB703WZ), blue window for dust protecon for the (OPB704,
OPB704WZ, OPB70BWZ, OPB70HWZ) and aperture lens for improved resoluon for the (OPB705, OPB705WZ, OPB70AWZ,
OPB70CWZ, OPB70DWZ). The OPB704G and OPB704GWZ offers excellent protecon for dirty environments.
The phototransistor responds to illuminaon from the emier when a reflecve object passes within the field of view centered
typically at 0.15” (3.8 mm).
Custom electrical, wire, cabling and
connectors are available. Contact
your local representave or OPTEK
for more informaon.
