What Are Absolute Encoders and When to Use Them

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.

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
