Pololu QTRX-HD-06RC Reflectance Sensor Array: 6-Channel, 4mm Pitch, RC Output, Low Current

The QTRX-HD-06RC Reflectance Sensor Array is a 6-channel, 4mm pitch, RC output, low current device. It's a compact unit, measuring just 25.0mm x 20.0mm. The array is designed for identifying changes in reflectance, making it ideal for line detection. The sensor array has a maximum LED current of 3.5mA and a board current of 14mA. It operates from 2.9V to 5.5V and has an optimal range of 10mm. The QTRX-HD-06RC Reflectance Sensor Array features an array of IR LED/phototransistor pairs. It's designed to offer precise identification of changes in reflectance. This makes it particularly useful in robotics and automation, where line detection is often required. The sensor array offers dimmable brightness control that's independent of the supply voltage. This means you can adjust the brightness to suit your specific needs, without affecting the power supply.One of the unique properties of the QTRX-HD-06RC Reflectance Sensor Array is the separate controls for the odd and even emitters. This feature allows for more precise control and customization, enhancing the functionality of the sensor array. The closer the object to the sensor, the higher the contrast between light and dark readings. However, high-reflectance objects are generally detectable up to around 40mm. This makes the sensor array versatile and adaptable to a variety of applications.Another key benefit of the QTRX-HD-06RC Reflectance Sensor Array is its low current design. This version of the sensor array features high-performance, low-current QTRX sensors with lenses. This means it's not only efficient but also delivers superior performance. This makes it a reliable choice for applications that require precise and reliable reflectance detection.
