Aura® Series
Absolute Optical Sensors
Superior resolution, seamless integration
Aura | Aura P
Absolute
High Resolution
Low Power
Aura employs a short wavelength LED for precise absolute position decoding. An incremental scale track and advanced sensor
produce pure sine wave signals, enabling high resolution interpolation with run-speeds up to 83,721 rpm (with 18 mm scale).
Aura P is an extension to the Aura Optical Encoder Series, offering a connectivity-ready high resolution absolute encoder in a super-compact form-factor. Maintaining its well-known high accuracy, run speed, and wide alignment tolerances, Aura P is now easier to install and integrate than ever, reducing overall time-to-market.
