Reflective Object Sensor OPB708, OPB709, OPB740 Series, OPB740WZ Series

The OPB708, OPB709, OPB740 through OPB746, and OPB740WZ through OPB746WZ series are reflective object sensors. Each unit comprises an infrared emitting diode and either an NPN silicon phototransistor or a photodarlington. The OPB747WZ and OPB748WZ feature a Red visible LED paired with a low light level rejection (RBE) NPN silicon phototransistor, offering improved contrast for detecting black marks on white surfaces. These sensors are designed with side-by-side mounting on converging optical axes within a black plastic housing, focusing on a specific area and depth of field. The OPB_WZ series are wired devices (UL approved wire) with various lens options, including no windows, blue polysulfone windows for dust protection, or opaque aperture windows with offset openings for enhanced target resolution. The photosensor in these devices activates only when a reflective object enters its field of view. Custom options for IC(ON) current binning, wire lengths, and connectorization are available.

Applications:

Non-contact reflective object sensor
Assembly line automation
Machine automation
Machine safety
End of travel sensor
Door sensor
Thermal Paper Mark

Features:

Focused for maximum sensitivity
Phototransistor or photodarlington output
Crosstalk does not exceed specified ICEO
24 (610 mm) wire length
26 AWG wire size

Product Attributes:

Brand: TT electronics plc
Origin: USA (implied by address)
Material: Black plastic housing, Polysulfone windows (for some models)
Certifications: UL approved wire (for WZ series)
