HEIDENHAIN LF 183C Linear Encoder
Catalog photo shows the LF 183. It is not a photo of the LF 183C; check your unit's ID tag.
The HEIDENHAIN LF 183C (also written LF183C) 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. Same catalog page as the LF 183. The LF 183C differs by its distance-coded reference marks. Values are catalog values for this model; confirm your unit's configuration from its ID tag.
