OPB733TR - Reflective Object Sensor

General Description

The OPB733TR consists of an 890nm, Infrared Light Emitting Diode (LED) and an NPN silicon Phototransistor, which are mounted “side-by-side” on parallel axes in a miniature surface mount grey plastic housing.

Key Features

  • Unfocused for sensing diffuse surfaces.
  • Uses lensed devices for collimation of light beam.
  • Low-cost plastic housing.
  • Compact surface mount package 0.300” x 0.160” x 0.114” [7.6mmx4.1mmx2.9mm].
  • Typical peak emission wavelength 890nm.
  • Reduced visible ambient light sensitivity.
  • Optimal operating distance range 0.4” [10.2mm] to 1.0” [25.4mm].
