QTRX 4 Channel Reflectance Array 4mm Pitch

This array of IR LED/phototransistor pairs is great for precisely identifying changes in reflectance (like line detection). It operates from 2.9V to 5.5V 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 40mm. This version features high-performance, low-current QTRX sensors with lenses.
