An electromechanical switch that is employed as an angular position sensor is known as a rotary encoder. The output that is produced is generally a digital encoding of relative or absolute position, even though it is said that there are few rotary encoders with sinusoidal outputs. It is known that the rotary encoder is generally being attached with a microprocessor. Its employment can be found in numerous industrial applications as well as in various human-computer input devices. 更多
