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

The QTRX-HD-09A Reflectance Sensor Array is a 9-Channel, 4mm Pitch, Analog Output, Low Current product that is a part of Pololu's Sparkfun range. With a size of 37.0 x 20.0mm, this array has a maximum LED current of 3.5mA and a board current of 22mA. The optimal range of this sensor array is 10mm.

Equipped with a series of IR LED/phototransistor pairs, the QTRX-HD-09A Reflectance Sensor Array is perfect for accurately detecting changes in reflectance, such as line detection. It operates within a voltage range of 2.9V to 5.5V. The array offers adjustable brightness control that is independent of the supply voltage, with separate controls for the odd and even emitters.

The closer the object is to the sensor, the greater the contrast between light and dark readings. However, high-reflectance objects can generally be detected up to approximately 40mm. The QTRX-HD-09A Reflectance Sensor Array features high-performance, low-current QTRX sensors with lenses, ensuring superior performance and efficiency.

With its compact size and high precision, the QTRX-HD-09A Reflectance Sensor Array is ideal for applications where accurate line detection and reflectance changes are crucial. Its low current consumption makes it a sustainable choice for projects requiring long operational periods. The inclusion of lenses on the QTRX sensors allows for enhanced detection capabilities, making this sensor array a reliable choice for a wide range of applications.
