Aura employs a short wavelength LED for precise absolute position decoding. An incremental scale track and advanced sensor produce pure sinewave signals, enabling high resolution interpolation with run-speeds up to 83,721 rpm (with 18 mm scale). High repeatability and accuracy satisfy the most demanding applications.

Mercury II’s advanced sensor design achieves resolutions up to 1.2nm and high accuracy performance in a compact sensor body.

Mercury II™ digital output high-vacuum rated encoders offer class-leading resolution, accuracy, and small sensor size.
