Used encoders (all tested and working)

The HEIDENHAIN EQI 1331 32 62S12-78 (ID 623 079-51) is a high-precision absolute rotary encoder designed for accurate position measurement in industrial motion control and servo drive systems. Manufactured by HEIDENHAIN, it belongs to the EQI 1300 series, which uses a robust inductive scanning principle to deliver reliable position data even in demanding environments. The encoder features a blind hollow shaft design for direct mounting on motor shafts and offers high positioning accuracy with up to 524,288 positions per revolution. It communicates digitally through interfaces such as EnDat or DRIVE-CLiQ and is widely used in servo motors, CNC machines, robotics, and automated manufacturing systems requiring precise and stable rotational feedback.
