QTRX-HD-11A Reflectance Sensor Array: 11-Channel, 4mm Pitch, Analog Output, Low Current

The QTRX-HD-11A Reflectance Sensor Array is a versatile and precise device that features 11 channels, a 4mm pitch, and an analog output. Its compact size of 45.0mm x 20.0mm makes it suitable for a variety of applications. The sensor array operates efficiently with a maximum current of 3.5mA for the LED and 26mA for the board. It offers an optimal range of 10mm, making it ideal for detecting changes in reflectance, such as line detection.

The QTRX-HD-11A Reflectance Sensor Array is equipped with an array of IR LED/phototransistor pairs. These enable it to precisely identify changes in reflectance. This feature makes it a valuable tool for applications that require precise line detection or object differentiation based on reflectance.

Operating from 2.9V to 5.5V, this sensor array offers dimmable brightness control. This control is independent of the supply voltage and provides separate controls for the odd and even emitters. This feature allows for greater customization and precision in various lighting conditions.

Despite its compact size, the QTRX-HD-11A Reflectance Sensor Array offers a surprisingly large detection range. In general, the closer the object, the higher the contrast between light and dark readings. However, high-reflectance objects are generally detectable out to around 40mm. This makes the sensor array versatile and adaptable to a variety of scenarios and applications.

The QTRX-HD-11A Reflectance Sensor Array features high-performance, low-current QTRX sensors with lenses. These sensors are designed to deliver high performance with low power consumption, making the array a cost-effective and efficient solution for a wide range of applications.
