L-GAGE Q50 Series—Analog


Compact linear displacement sensor with scalable analog output

  • 15 to 30V dc supply voltage with 4-20 mA or 0-10V dc analog output, depending on model
  • Automatic scaling of the analog output over the width of the programmed sensing window
  • Visible red models with 50 to 150 mm or 100 to 300 mm sensing range
  • Infrared models with 50 to 200 mm or 100 to 400 mm sensing range
  • Push-button TEACH-mode programming for custom sensing windows
  • Remote programming for added security and convenience
  • Selectable output response speed of 4 to 64 milliseconds
  • Sensor linearity less than 1 percent of full scale
