QTRX-HD-04RC Reflectance Sensor Array: 4-Channel, 4mm Pitch, RC Output, Low Current

The QTRX-HD-04RC Reflectance Sensor Array is a 4-Channel, 4mm Pitch, RC Output, Low Current device that is designed to accurately identify changes in reflectance. This makes it particularly useful for applications such as line detection. The array size is 17.0mm x 20.0mm, and it operates from 2.9V to 5.5V. It has a maximum LED current of 3.5mA and a board current of 9mA. The optimal range for this device is 10mm.

The QTRX-HD-04RC Reflectance Sensor Array is equipped with an IR LED/phototransistor pair, which is highly effective in detecting the precise changes in reflectance. This feature makes it a practical tool for robotics applications where line detection or edge detection is required. The device also offers dimmable brightness control independent of the supply voltage, allowing users to adjust the device's brightness according to their needs.

One of the significant benefits of this sensor array is its ability to detect high-reflectance objects up to around 40mm. This is particularly beneficial in environments where objects with high reflectance are present. Furthermore, the closer the object, the higher the contrast between light and dark readings, which enhances the device's detection capabilities.

The QTRX-HD-04RC Reflectance Sensor Array features high-performance, low-current QTRX sensors with lenses. These lenses help to focus the IR LED light, improving the sensor's performance. This unique property makes this sensor array a reliable and efficient tool for various applications requiring precise reflectance detection.
