Incremental Encoders

Incremental encoders, also known as incremental shaft encoders and incremental rotary shaft encoders, are electro-mechanical devices that are designed to monitor a rotating shaft. When used in conjunction with ball screws and rollers, incremental encoders can also monitor linear positions. When incremental encoders are integrated into a control system, they can provide various useful data: speed, position, direction and acceleration. Incremental encoders are available in solid shaft, hollow shaft and semi-hollow shaft versions, but all types create two digital square-wave signals, referred to as A & B. Incremental encoders also feature a digital marker pulse (the reference pulse). This records a single pulse per shaft revolution and can be used as a reset and reference point. From servomotors to brushless motor applications, incremental encoders are used widely across many industries in applications that have unlimited shaft rotation.
