New products: 16 more QTR reflectance sensor arrays
Our rapidly growing selection of new QTR sensors now includes high-density (HD) versions with 13 and 25 channels, and medium-density (MD) versions with 7 and 13 channels. These QTR sensors are well suited for applications that require detection of changes in reflectivity. This change in reflectivity can be due to a color change at a fixed distance, such as when sensing a black line on a white background, as well as due to a change in the distance to or presence of an object in front of the sensor. Just like the 16-channel medium-density arrays we released in December, the 13-channel medium-density modules use PCBs specifically designed for an 8 mm pitch that allow separate control of the odd and even emitters, which gives you extra options for detecting light reflected at various angles. They have the same board dimensions (101 × 16.5 mm) and mounting hole locations as the high-density (4 mm pitch) 25-channel arrays, but the pinout is different.
Each of these is available with two sensor options—traditional QTR and high-performance, low-current QTRX—and with analog or digital (RC) outputs, making 16 new products in all. Check out the QTR reflectance sensor category to see our full selection of new-style QTRs with black PCBs, which now stands at 96 varieties, and don’t forget to use our QTR introductory promotion to get 50% off any of these new sensors!
