ERN1331 series is Heidenhain integrated-bearing incremental encoder specially matched to Siemens permanent magnet synchronous servo motors, widely used for machine tool feed axes, automation servo positioning systems.Model ERN1331.061‑1024 adopts standard 9.25mm 1:10 friction taper shaft, directly friction-locked onto servo motor rotor without extra flexible coupling; built-in stator floating anti-rotation mounting to compensate large axial installation tolerance up to ±0.5mm. It outputs HTL push-pull complementary A/B/Z square wave signals, compatible with all mainstream 10–30V servo drive PG interfaces, with strong driving load capacity and stable signal transmission over medium-long cable lengths. Equipped with 12-pin double-row straight locking plug, supports axial or radial cable outlet installation.
Resolution: 1024 PPR (90° phase-shifted A/B quadrature + single-turn Z reference pulse)
Signal Format: HTL push-pull complementary square wave (TTL compatible)
Supply Voltage: DC10 V ~ 30 V universal wide industrial voltage
