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

The OPB708, OPB709, OPB740 through OPB746, and OPB740WZ through OPB746WZ series reflective object sensors each comprise an infrared emitting diode and an NPN silicon phototransistor or photodarlington. The OPB747WZ and OPB748WZ feature a Red visible LED and a low light level rejection (RBE) NPN silicon phototransistor, offering enhanced contrast for detecting black marks on white surfaces. These devices are housed in a black plastic casing with side-by-side mounting on converging optical axes, designed for focused detection within a specific area and depth of field. The OPB_WZ series includes UL-approved wiring and various lens options for dust protection or improved target resolution. These sensors activate the photosensor only when a reflective object enters their field of view. Custom options for IC(ON) current binning, wire lengths, and connectorization are available.

Applications:

Non-contact reflective object sensing
Assembly line automation
Machine automation
Machine safety
End of travel sensing
Door sensing
Thermal paper mark detection

Features:

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