The LC 181 and LC 183 are sealed absolute linear encoders that have been discontinued. They are still common on machines that have years of life left in them, and we repair them.
Send the scale to our Mentor, Ohio shop. The evaluation is free, and a repair quote follows quickly. Rush turnaround is 1-2 days; standard is 1-2 weeks.
If the scale cannot be repaired, we can quote the current absolute encoder replacement and any interface changes it needs. We are an authorized Heidenhain distributor, so repair and replacement both run through one call: 1-888-354-2525 or our contact form.
