Heidenhain 329991-26 (LS 486C) Incremental Sealed Linear Encoder

Technical Specifications & Overview

The Heidenhain 329991-26 is an LS 486C series incremental sealed linear encoder engineered with a slimline housing cross-section for space-restricted motion control applications. Built for closed-loop position feedback on machine tools, this optical scale generates 1 Vpp sinusoidal voltage signals and utilizes distance-coded reference marks to allow rapid position determination after powering on.
