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.
The small, low power consumption SMT package integrates easily into an OEM PCB. Generous alignment tolerances facilitate installation. Built-in scale eccentricity compensation improves production efficiency and eliminates the cost of dual averaging encoders.
High speed BiSS-C delivers the minimal latency required for high bandwidth control loops. SSI, SPI and ABZ interfaces complete the comprehensive connectivity options. ABZ provides communication redundancy and the flexibility to operate incrementally for the lowest latency.
SmartPrecision™ III is intuitive software for calibration, alignment and status monitoring. Encoder data can be sampled and recorded in a CSV file. To simplify installation, hubs with pre-mounted encoder scales are offered.
