This sensor module has seven IR LED/phototransistor pairs mounted on a high-density 4 mm pitch, making it well suited for precisely identifying changes in contrast/reflectance (like line-detection). These units offer dimmable brightness control independent of the 2.9 V to 5.5 V supply voltage, with optional separate control of the odd and even sensor channel emitters. The optimal sensing distance is approximately 1 cm or less, but high-reflectance objects are generally detectable out to around 5 cm.

This version features high-performance QTRX sensors with lenses, and each sensor provides a separate digital I/O-measurable output. Max LED current is set to 3.5 mA, and the max board current is 15 mA.

Specifications:

  • Dimensions: 29 × 20 × 0.3 mm
  • Operating voltage: 2.9 V to 5.5 V
  • Max LED current: 3.5 mA
  • Max board current: 15 mA
  • Output format: 7 digital I/O-compatible signals that can be read as a timed high pulse
  • Optimal sensing distance: 1 cm
  • Maximum recommended sensing distance: 5 cm
  • Weight: 1.6 g
