Pololu Corporation

<p>The Pololu 4306 QTRX-HD-06RC is a 6-channel reflectance sensor array designed for precise line detection and reflectance measurement. It uses QTRX high-performance, low-current phototransistor sensors with lenses, arranged at a 4mm pitch on a compact 25.0 x 20.0 x 3.0 mm board.</p><p>&nbsp;</p><p>The array operates from 2.9V to 5.5V and features dimmable brightness control independent of supply voltage, with separate controls for odd and even emitters. Each sensor outputs a digital RC (resistor-capacitor) signal that can be read in parallel as timed high pulses. The full-brightness LED current is 3.5 mA, and the maximum board current is 14 mA.</p><p>&nbsp;</p><p>The optimal sensing distance is 10 mm, with a maximum recommended sensing distance of 40 mm for high-reflectance objects. The board weighs 1.5 g and includes mounting holes for #2 and M2 screws. Supplied contents include the board and accessories.</p>

<p>These premium wires are stranded 26 AWG copper wires with male crimp pins on both ends. Each wire measures 2" (50.8mm) in length and has blue insulation. The pack contains 10 wires.</p><p>&nbsp;</p><p>Together with 0.1" (2.54mm) crimp connector housings, these wires can be used to make custom cables with 0.1" connectors. The pre-crimped terminals allow for quick prototyping connections without soldering.</p><p>&nbsp;</p><p>The wires are designed for use with 0.1" male headers, female headers, solderless breadboards, and prototyping PCBs. They can also be cut and soldered directly to components.</p>
