The Smart Incremental series from Han's Scanner is an open, non-contact universal grating ruler system. The reading head is compact and small, with built-in LED indicators for installation, outputs digital signals with resolutions as low as 32nm, and incorporates an integrated optical Index mark sensor probe.
