QTRX-MD-04A Reflectance Sensor Array: 4-Channel, 8mm Pitch, Analog Output, Low Current

The QTRX-MD-04A Reflectance Sensor Array is a 4-Channel, 8mm Pitch device with an Analog Output and Low Current. This compact sensor, measuring 29.0 x 20.0mm, is designed to precisely identify changes in reflectance, making it perfect for line detection tasks. It operates in a voltage range of 2.9V to 5.5V and features a dimmable brightness control that is independent of the supply voltage. The maximum current for the LED and the board are 3.5mA and 9mA respectively. The optimal range for this sensor is 10mm.

The QTRX-MD-04A is equipped with an array of IR LED/phototransistor pairs. This makes it highly sensitive to changes in reflectance. In general, the closer the object, the higher the contrast between light and dark readings. However, it is also capable of detecting high-reflectance objects up to around 40mm. This makes it a versatile tool for a variety of applications.

One of the standout features of this sensor array is its low current QTRX sensors with lenses. These high-performance sensors enable the device to deliver precise and reliable readings while consuming minimal power. This makes the QTRX-MD-04A an energy-efficient choice for your sensing needs.

Whether you are developing a line-following robot, a hand dryer that senses the presence of hands, or any other device that requires precise reflectance detection, the QTRX-MD-04A Reflectance Sensor Array is a reliable and efficient solution. Its compact size, low power consumption, and high sensitivity make it an excellent choice for a wide range of applications.
