Pololu QTRX-HD-09RC Reflectance Sensor Array: 9-Channel, 4mm Pitch, RC Output, Low Current

The QTRX-HD-09RC Reflectance Sensor Array is a high-performing, low-current product with a 9-channel, 4mm pitch, RC output and low current features. Its dimensions are 37.0mm by 20.0mm. The array has a maximum current capacity for the LED of 3.5mA and for the board of 22mA, with an optimal range of 10mm. The sensor array is equipped with an array of IR LED/phototransistor pairs, making it an excellent choice for accurately identifying changes in reflectance, such as line detection. It functions within a voltage range of 2.9V to 5.5V and offers adjustable brightness control, independent of the supply voltage. Additionally, it provides separate controls for the odd and even emitters.One of the unique properties of this sensor array is that the contrast between light and dark readings increases as the object gets closer. However, high-reflectance objects can generally be detected up to approximately 40mm. This version of the sensor array is equipped with high-performance, low-current QTRX sensors with lenses, ensuring optimal performance and efficiency.Whether you're a professional looking for a reliable sensor array or a hobbyist working on a new project, the QTRX-HD-09RC Reflectance Sensor Array is a versatile and reliable choice that offers precise and accurate results. Its low-current features and high performance make it a cost-effective and energy-efficient solution for a variety of applications.
