QTRX-MD-01A Reflectance Sensor: 1-Channel, 7.5mm Wide, Analog Output, Low Current
|1||7.5 × 20.0||analog||3.5 mA||5 mA||10 mm|
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 30 mm. This version features a high-performance, low-current QTRX sensor with lenses.
