Additional Details

The QEDS-9874 module operates based on the principle of optical encoding. An LED light source shines through a code wheel, and the resulting light patterns are detected by a sensor IC. The sensor generates two quadrature output signals, A and B, which are 90 degrees out of phase. By analyzing the phase relationship between these signals, the direction and amount of rotation can be accurately determined. The specific resolution is determined by the code wheel used.
