A\u00a0rotary encoder<\/b>, also called a\u00a0shaft encoder<\/b>, is an\u00a0electro-mechanical<\/a>\u00a0device that converts the\u00a0angular<\/a>\u00a0position or motion of a shaft or axle to analog or digital output signals.<\/p>\n

There are two main types of rotary encoder: absolute and incremental. The output of an absolute encoder indicates the current shaft position, making it an\u00a0angle transducer<\/a>. The output of an incremental encoder provides information about the\u00a0motion<\/i>\u00a0of the shaft, which typically is processed elsewhere into information such as position, speed and distance.<\/p>\n

Rotary encoders are used in a wide range of applications that require monitoring or control, or both, of mechanical systems, including industrial controls,\u00a0robotics<\/a>,\u00a0photographic lenses<\/a>,[1]<\/a><\/sup>\u00a0computer input devices such as optomechanical\u00a0mice<\/a>\u00a0and\u00a0trackballs<\/a>, controlled stress\u00a0rheometers<\/a>, and rotating\u00a0radar<\/a>\u00a0platforms.<\/p>\n
