OPB744 - Reflective Object Sensor

Download the OPB744 datasheet PDF. This datasheet also covers the OPB708 variant, as both devices belong to the same reflective object sensor family and are provided as variant models within a single manufacturer datasheet.

Description

Each reflective object sensor in the OPB708, OPB709, OPB740 through OPB746 and OPB740WZ through OPB746WZ series consists of an infrared emitting diode and a NPN silicon phototransistor or a photodarlington.

Features

  • Focused for maximum sensitivity.
  • Phototransistor or photodarlington output.
  • Crosstalk does not exceed specified ICEO.
  • 24” (610 mm) wire length.
  • 26 AWG wire size OPB708, OPB709, OPB740, OPB745 Series OPB7_ _WZ Series.

The OPB747WZ and OPB748WZ consist of a Red visible LED and a low light level rejection (RBE) NPN silicon phototransistor. The Red LED allows better contrast ratio when detecting Black marks on a White surface.
