There are three basic configurations for optical encoders: incremental, absolute, and multiturn absolute encoders. Each delivers different performance characteristics, capabilities, and benefits.

A few different approaches can be taken to build multi-turn, absolute encoders. All usually start with a basic incremental or single-turn absolute encoder.

Also, because absolute encoders don’t continuously stream their data like incremental encoders, they may not be well-suited for some high-speed applications. Pseudo-absolute encoders, also known as ...

AutomationDirect has expanded its Koyo encoder product line to include additional incremental encoder output options and higher resolutions for absolute encoders.

The encoder output governs the category of the encoder’s category: incremental or absolute. An incremental encoder provides speed and distance feedback of any linear and rotary system.

Three encoder choices are available, two sine/cosine encoders for traditional motion controllers and an absolute encoder with BiSS-C transfer protocol.

Avago Technologies announced a high-resolution absolute optical encoder for high-performance servo and motor feedback applications.
