Shaft diameter: 6mm/0.24"; Shaft height: 15mm/0.59"; Thread diameter: 6.8mm/0.27"; Overall dimensions: 15mm x 12.5mm x 30mm / 0.59" x 0.49" x 1.18" (L*W*H).
In forward rotation, the phase of line A leads the phase of line B; When reversed, the phase of line B leads the phase of line A. The phase relationship and the number of rotations of AB can be determined using a simple digital logic circuit (exclusive OR gate and D flip-flop). By rotating the rotary encoder, the output pulse frequency can be counted in both the forward and reverse directions. Unlike a rotary potentiometer, this rotation is unlimited. The rotary encoder can be reset to its initial state, which starts counting from 0, using the knobs. Applications: Industrial controls, robotics, photographic lenses, computer input devices such as optomechanical mice and trackballs, and controlled rheometers.
