DESCRIPTION
This array of IR LED/phototransistor pairs is great for precisely identifying changes in reflectance (like line detection). It operates from 2.9V to 5.5V and offers dimmable brightness control independent of the supply voltage. In general, the closer the object, the higher the contrast between light and dark readings, but high-reflectance objects are generally detectable out to around 30mm.
These reflectance sensors feature a linear array of IR emitter/phototransistor pair modules in a high-density (4mm pitch) or medium-density (8mm pitch) arrangement, which makes them well suited for applications that require the detection of changes in reflectivity. This change in reflectivity can be due to a colour change at a fixed distance, such as when sensing a black line on a white background, as well as due to a change in the distance to or presence of an object in front of the sensor. A variety of sensor counts and densities is available so you can pick the ideal arrangement for your application. Since the outputs are all independent, you can connect just some of the channels to attain an irregular or non-standard sensor spacing.
These units have integrated LED drivers that provide brightness control independent of the supply voltage, which can be anywhere from 2.9V to 5.5V, while enabling optional dimming to any of 32 possible brightness settings. For high-density (HD) modules with five or more sensors, there are separate controls for the odd-numbered and even-numbered LEDs, which gives you extra options for detecting light reflected at various angles.
This QTRX version features higher-performance sensor modules with lenses, which allow high performance at a much lower IR LED current.

Prior to shipment before shipping, we'll conduct a thorough inspection of the items you've ordered. The majority of orders today are shipped in 48 hours. The estimated delivery time is between 3 and 7 days.
Returns
The stock is constantly changing and is not completely managed by us due to the involvement of several parties including the factory and our warehouse. Therefore, the actual inventory could fluctuate at any moment. It's possible that your order could run out of stocks once you've placed your order.
The period of time is 30 days. If you haven't received the product within the 30 days period, we're not able to issue either a return or exchange.
To be eligible for a return the product must be unopened and in the same condition that you received it in. It must also remain in the original packaging.
