The HEIDENHAIN ERN 420 2968 94S05‑0X (ID 385 429‑53) is a compact, incremental rotary encoder with integrated bearing and stator coupling, designed for precision motion control in demanding industrial environments. It delivers high-resolution TTL/HTL output (typically up to 5,000 lines), offers excellent dynamic performance, and directly mounts on the shaft without additional rotor coupling. Featuring IP64 protection, operating temperatures from –40 °C to +100 °C, and a rugged Ø56 mm housing, it compensates for axial misalignment (±1 mm), enabling reliable, accurate feedback for servo drives, automation systems, and CNC machinery.
