QTRXL-HD-01RC Reflectance Sensor: 1-Channel, 5mm Wide, RC Output, Long Range
This IR LED/phototransistor pair 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. 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 80 mm. This version features a high-performance QTRXLsensor with lenses and a high-brightness emitter for extra-long range.
