Product Description<\/b><\/h4>\n

This array of IR LED\/phototransistor pairs is great for precisely identifying changes in reflectance (like line detection). It operates from 2.9\u00a0V to 5.5\u00a0V 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\u00a050\u00a0mm. This version features high-performance, low-current\u00a0QTRX\u00a0sensors with lenses<\/p>\n
