QTR-MD-07RC Reflectance Sensor Array: 7-Channel, 8mm Pitch, RC Output

The Pololu QTR-MD-07RC Reflectance Sensor Array is a versatile and precise 7-channel device with an 8mm pitch and RC output. It measures 53.0mm x 20.0mm in size and has a maximum current capacity of 30mA for the LED and 125mA for the board. This sensor array is designed to excel in detecting changes in reflectance, making it an ideal choice for tasks such as line detection.

The QTR-MD-07RC operates efficiently within a voltage range of 2.9V to 5.5V. It also features a dimmable brightness control that functions independently of the supply voltage. This feature offers flexibility and adaptability to various working conditions.

One of the unique properties of this sensor array is its high contrast ratio between light and dark readings when the object is closer. It can generally detect high-reflectance objects up to around 40mm. This makes it a reliable tool for tasks that require precision and accuracy.

Unlike other models, this version of the QTR-MD-07RC Reflectance Sensor Array comes without lenses. This traditional-style design contributes to its robustness and durability, ensuring that it can withstand rigorous usage.

Whether you're involved in robotics, automation, or any project that requires precise detection of changes in reflectance, the Pololu QTR-MD-07RC Reflectance Sensor Array is a reliable choice. Its compact size, high contrast ratio, and lens-less design make it a stand-out option in its category.
