Description

This array of IR LED/phototransistor pairs is great for precisely identifying changes in reflectance (like line detection). It operates from 2.9 V to 5.5 V and offers dimmable brightness control independent of the supply voltage and separate controls for the odd and even emitters. In general, the closer the object, the higher the contrast between light and dark readings, but high-reflectance objects are generally detectable out to around 50mm.

Specifications:

  • Dimensions: 61.0 × 20.0 × 2.5 mm
  • Operating voltage: 2.9 V to 5.5 V
  • Sensor type: QTR
  • Sensor count: 15
  • Sensor pitch: 4 mm
  • Full-brightness LED current: 30 mA (independent of supply voltage)
  • Max board current: 250 mA
  • Output format: digital I/O-compatible signals that can be read in parallel as timed high pulses
  • Optimal sensing distance: 5 mm
  • Maximum recommended sensing distance: 50 mm
  • Weight: 3.5 g
