Absolute Encoder

Absolute Encoder

Absolute encoders are feedback devices that provide speed, position information by outputting a digital word or bit in relation to motion.
Compared to incremental encoders, absolute encoder always outputs with a continuous stream of ubiquitous pulses, it outputs unique words or bits for each position.

By outputting a digital word or bit instead of a stream of pulses, absolute rotary encoders offer several advantages:
1.Higher overall resolution than incremental encoders
2.Better start up performance because of low homing (or initial position) time
3.Accurate motion detection along multiple axes
3.Multiple output protocols for better electronics integration to meet with various applications.
4.Better recovery from system or power failures to shorten the motor workinglife.
