What Are Absolute Encoders and When to Use Them

Overview

Learn all about Absolute Encoders and their use cases. Whether it be for motion feedback or position indication, absolute encoders are a staple in modern day industries.

Absolute Encoders - What are they?

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

Absolute Encoders

By outputting a digital word or bit instead of a stream of pulses, absolute rotary encoders offer several advantages:

  • Higher overall resolution vs incremental encoders
  • Better start up performance because of low homing (or initial position) time
  • Accurate motion detection along multiple axes
  • Multiple output protocols for better electronics integration
  • Better recovery from system or power failures
