Barcode Sensors

Opto Technology has developed a line of fixed position Barcode Sensors that are ideal for small embedded OEM applications. These sensors can be used for scanning barcode elements or as high resolution mark/ code detectors. They incorporate visible red or infrared LEDs, photo-detectors, precision optical lens, and an optical aperture. All of these components are packaged into a polycarbonate housing.
 
 Complete custom versions are also available to fit your specific scanning application.

Typical Applications

  • Barcode coupon validation
  • Time and attendance equipment
  • Medical blood analyzers
  • Slot/card readers

Features

  • Available in 660nm and 940nm LED wavelengths
  • Able to resolve 0.007" to 0.020" element with barcode patterns
  • Small compact package. Able to fit in small OEM applications
  • Standard single or dual LED sensors heads (dependent on sensing distance)
  • Phototransistor or Photodiode detectors available
  • Custom screening for ranges of output current of photo detectors
  • Low cost
  • No moving parts/ High reliability
