The Pololu QTR-MD-02A Reflectance Sensor Array is a top-notch device designed with 2-channel, 8mm pitch, and analog output. It is a compact size of 13.0mm x 20.0mm. This array is specially designed with IR LED/phototransistor pairs, making it exceptional for identifying changes in reflectance, such as line detection. The QTR-MD-02A operates from 2.9V to 5.5V and has a unique feature of dimmable brightness control, independent of the supply voltage. This makes it a versatile device for various applications. The maximum current for the LED and the board are 30mA and 32mA respectively, ensuring optimal performance.The sensor array is designed to work best at an optimal range of 5mm. However, high-reflectance objects can generally be detected out to around 30mm. This makes it an excellent choice for tasks that require precision and accuracy. This version of the sensor array features the traditional-style QTR sensors without lenses, offering a straightforward and efficient design.Whether you're working on a robotics project, a DIY electronics task, or a professional engineering assignment, the Pololu QTR-MD-02A Reflectance Sensor Array is a reliable and efficient tool. Its unique features and compact design make it a must-have for any tech enthusiast. https://elecena.pl/product/27749413/pololu-qtr-md-02a-reflectance-sensor-array-2-channel-8mm-pitch-analog-output 2025-01-23 https://elecena.pl/product/27749413/pololu-qtr-md-02a-reflectance-sensor-array-2-channel-8mm-pitch-analog-output 2025-11-27 https://elecena.pl/product/27749413/pololu-qtr-md-02a-reflectance-sensor-array-2-channel-8mm-pitch-analog-output 2026-01-04 https://elecena.pl/product/27749413/pololu-qtr-md-02a-reflectance-sensor-array-2-channel-8mm-pitch-analog-output 2026-02-08 https://elecena.pl/product/27749413/pololu-qtr-md-02a-reflectance-sensor-array-2-channel-8mm-pitch-analog-output 2026-03-05 https://elecena.pl/product/27749413/pololu-qtr-md-02a-reflectance-sensor-array-2-channel-8mm-pitch-analog-output 2026-03-07 https://elecena.pl/product/27749413/pololu-qtr-md-02a-reflectance-sensor-array-2-channel-8mm-pitch-analog-output 2026-03-14 https://elecena.pl/product/27749413/pololu-qtr-md-02a-reflectance-sensor-array-2-channel-8mm-pitch-analog-output 2026-03-19 https://elecena.pl/product/27749413/pololu-qtr-md-02a-reflectance-sensor-array-2-channel-8mm-pitch-analog-output 2026-04-12 https://elecena.pl/product/27749413/pololu-qtr-md-02a-reflectance-sensor-array-2-channel-8mm-pitch-analog-output 2026-04-24 https://elecena.pl/product/27749413/pololu-qtr-md-02a-reflectance-sensor-array-2-channel-8mm-pitch-analog-output 2026-04-28 https://elecena.pl/product/27749413/pololu-qtr-md-02a-reflectance-sensor-array-2-channel-8mm-pitch-analog-output 2026-05-06 https://elecena.pl/product/27749413/pololu-qtr-md-02a-reflectance-sensor-array-2-channel-8mm-pitch-analog-output 2026-05-10 https://elecena.pl/product/27749413/pololu-qtr-md-02a-reflectance-sensor-array-2-channel-8mm-pitch-analog-output 2026-05-18 https://elecena.pl/product/27749413/pololu-qtr-md-02a-reflectance-sensor-array-2-channel-8mm-pitch-analog-output 2026-06-07 https://elecena.pl/product/27749413/pololu-qtr-md-02a-reflectance-sensor-array-2-channel-8mm-pitch-analog-output 2026-06-26 https://elecena.pl/product/27749413/pololu-qtr-md-02a-reflectance-sensor-array-2-channel-8mm-pitch-analog-output 2026-06-30
