D12 Expert Series


  • Easy push-button TEACH-mode programming to automatically adjust sensitivity to optimal setting
  • 10 to 30V dc supply voltage with NPN or PNP output, depending on model
  • Light-operate or dark-operate selectable
  • Available with low-contrast sensing
  • Switching threshold setting for subtle changes, such as web flutter
  • LED bargraph for signal strength, sensing contrast, programming status and diagnostic warnings
  • Glass and plastic fiber optic models
  • Marginal gain indicator with alarm output

Product Specifications
