HEIDENHAIN LC 493F Linear Encoder
Representative HEIDENHAIN LC-series linear encoder pictured; not the exact LC 493F model. Check your unit's ID tag for its configuration.
The HEIDENHAIN LC 493F (also written LC493F) is a linear encoder. If yours is giving trouble, Automation and Metrology can evaluate it before you commit to a replacement. We work on older encoders, including units that may no longer be available new.
we specialize in machine down linear encoder repair or replacement
How it works: Send us your scale for a free evaluation. We will give you a repair quote quickly, before work starts.
Turnaround: Rush repairs typically take 1-2 days; standard repairs typically take 1-2 weeks. We will confirm the timing for your unit with the quote. If repair is not practical, we can help identify a suitable current HEIDENHAIN replacement.
Catalog specifications
From the HEIDENHAIN Linear Encoders for Numerically Controlled Machine Tools catalog, July 2010. Printed in the 2010 catalog on the same page as the LC 483 and LC 493M. This page lists the LC 493F column only. Values are catalog values for this model; confirm your unit's configuration from its ID tag.
