HEIDENHAIN LB 382C Linear Encoder
Representative HEIDENHAIN LB-series linear encoder pictured; not the exact LB 382C model. Check your unit's ID tag for its configuration.
The HEIDENHAIN LB 382C (also written LB382C) 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 on catalog pages 33 and 35, which cover both the LB 382 and LB 382 C; the reference mark row below is the difference between them. This page lists the LB 382 C entries. Values are catalog values for this model; confirm your unit's configuration from its ID tag.
