QTRX-MD-02RC Reflectance Sensor Array: 2-Channel, 8mm Pitch, RC Output, Low Current
|pitch × sensors||size
|8 mm × 2||13.0 × 20.0||RC (digital)||3.5 mA||5 mA||10 mm|
This array of IR LED/phototransistor pairs 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 high-performance, low-current QTRX sensors with lenses.
