Pololu QTRXL-HD-01RC Reflectance Sensor: 1-Channel, 5mm Wide, RC Output, Long Range

The QTRXL-HD-01RC Reflectance Sensor is a 1-channel, 5mm wide sensor with RC output and long-range capabilities. It's an exceptional IR LED/phototransistor pair that's specifically designed to accurately identify changes in reflectance, such as those required for line detection. With a size of 5.0 x 20.0mm, the sensor operates from 2.9V to 5.5V and offers adjustable brightness control that is independent of the supply voltage. It has a maximum LED current of 30mA and a board current of 32mA. The optimal range for this sensor is 20mm.The QTRXL-HD-01RC Reflectance Sensor's performance is heightened when the object is closer, as this increases the contrast between light and dark readings. However, it's also capable of detecting high-reflectance objects at a distance of approximately 80mm. This sensor is equipped with a high-performance QTRXL sensor with lenses and a high-brightness emitter, which expands its range significantly.This sensor is an ideal solution for robotics and automation applications where precise line detection and reflectance changes identification are crucial. Its small size and long range make it versatile and suitable for a wide array of applications. The dimmable brightness control allows for energy efficiency and adaptability to different environments. The QTRXL-HD-01RC Reflectance Sensor is a reliable and high-performance tool for all your reflectance sensing needs.
