Understanding Renishaw's optical encoder technology

Access key information on how Renishaw optical encoders work. Learn about our wide range of optical linear, partial arc and rotary (angle) encoder systems.

Discover how Renishaw optical encoder technology can support you

Find further information about Renishaw's optical encoder technology. Compare encoder specifications across our product range, including scale options, length, speed and readhead size.

We manufacture our encoders to last. Rigorous testing ensures that our products are suitable for many reliability-critical applications where the encoder must perform faultlessly.

We design our Renishaw encoders for use in highly-dynamic applications, which may involve shock and vibration, as well as rapid moves and constant flexing. Under demanding conditions, our encoders deliver reliable position feedback.
