Legacy ERN 620 / ERN 630 inquiry

we specialize in machine down rotary encoder repair or replacement

Ask AMI to review a HEIDENHAIN ERN 620 or ERN 630 rotary encoder for repair or replacement. Historical HEIDENHAIN mounting instructions identify these models. Do not select a current ROD 600-series encoder by a similar model number alone.

Send the complete HEIDENHAIN ID number, a nameplate photo, signal interface, line count, shaft dimensions, cable or connector details, and machine application. Any replacement must be checked against the original installation and electronics.
