Pololu QTRXL-MD-01RC Reflectance Sensor: 1-Channel, 7.5mm Wide, RC Output, Long Range

The QTRXL-MD-01RC Reflectance Sensor is a compact, 1-channel sensor with a width of 7.5mm and a length of 20mm. This sensor uses RC (digital) output and has a maximum current capacity for both the LED and board of 30mA and 32mA respectively. It operates optimally within a range of 20mm. Equipped with an IR LED/phototransistor pair, the QTRXL-MD-01RC Reflectance Sensor excels in identifying changes in reflectance, making it an ideal choice for tasks such as line detection. It operates within a voltage range of 2.9V to 5.5V and allows for dimmable brightness control that is independent of the supply voltage.The sensor's performance is enhanced when the object is closer, creating a higher contrast between light and dark readings. However, it also has the capability to detect high-reflectance objects at a distance of up to 80mm. This model features a high-performance QTRXL sensor, equipped with lenses and a high-brightness emitter, ensuring a longer range of operation.With its unique properties and versatile usage, the QTRXL-MD-01RC Reflectance Sensor is a valuable addition to any project that requires precise detection and measurement of changes in light reflectance. Its compact size, high performance, and long range make it a reliable and efficient tool for a variety of applications.
