Celera Motion announced new sizes and capabilities for its Aura Absolute Chip Encoder Series of rotary and linear optical encoders with MicroE technology.
The Aura encoder line extension products will meet all the typical sizes needed in a robot arm, from small end effectors at the end of the arm to the upper shoulder joints.
Aura is an optimal solution for high-volume OEM applications including:
- Surgical robots
- Cobots, robot joints and grippers
- Exoskeleton and wearables
- Semiconductor
The Aura line extension enables an even wider range of customizable scale sizes, along with standard glass offerings ranging from 18mm to 63.5mm rotary OD and new-to-market linear scales lengths ranging from 9mm to 195mm.
Aura solves the largest source of angular error, eccentricity, which is caused by off-center scale mounting and bearing runout. Two encoders are often employed to compensate for the error increasing cost and power consumption. Aura solves the eccentricity problem with its built-in compensation algorithm thereby eliminating the need for the second encoder.
Among Aura’s other benefits:
- Absolute position feedback for high-performance, high-volume designs
- High resolution and accuracy for precision control needs
- Wide alignment tolerances provide ease of integration resulting in higher productivity
- Built-in eccentricity compensation for minimal angle error and easier installation
- Low-power dissipation for tight temperature budget applications
- Comprehensive connectivity meets industry standard interface requirements: BiSS-C, SSI & SPI
- AqB plus index provides additional incremental data to be used as secondary position information
Global application support is available to meet customer’s integration challenges.
