QTR-HD-09A Reflectance Sensor Array: 9-Channel, 4mm Pitch, Analog Output

The QTR-HD-09A Reflectance Sensor Array is a 9-channel device with a 4mm pitch and an analog output. It measures 37.0mm x 20.0mm in size and has a maximum current capacity of 30mA for the LED and 155mA for the board. The optimal range for this device is 5mm.

The QTR-HD-09A Reflectance Sensor Array is perfect for accurately detecting changes in reflectance. This makes it particularly useful for applications such as line detection. The array operates from 2.9V to 5.5V, providing flexibility for different power sources.

One of the standout features of this sensor array is its dimmable brightness control. This control is independent of the supply voltage, offering maximum flexibility in managing the brightness of the LEDs. Additionally, it has separate controls for the odd and even emitters, allowing for more precise adjustments.

The QTR-HD-09A Reflectance Sensor Array is designed to provide high contrast between light and dark readings when the object is closer. However, it can generally detect high-reflectance objects up to around 40mm away. This version of the array features the traditional-style QTR sensors without lenses, offering a straightforward, uncomplicated design.

With its precision, flexibility, and high detection range, the QTR-HD-09A Reflectance Sensor Array is an excellent choice for projects requiring accurate reflectance detection.
