Celera Motion, a business unit of Novanta Inc., has added additional sizes and capabilities for its AuraTM Absolute Chip Encoder Series of rotary and linear optical encoders with MicroE technology.

The updated Aura encoder line products are designed to meet typical robot arm size needs, from small end effectors at the end of the arm to the upper shoulder joints.

It also offers absolute position feedback for high performance, high volume designs. For precision control needs, Aura features high resolution and accuracy. Wide alignment tolerances provide ease of integration. Low-power dissipation is suited for tight temperature budget applications. Its comprehensive connectivity meets industry standard interface requirements BiSS-C, SSI and SPI. AqB plus index provides additional incremental data to be used as secondary position information. The company offers global application support available to meet customer’s integration challenges.

The Aura line extension is designed to enable a wider range of customizable scale sizes, along with standard glass offerings ranging from 18-63.5 mm rotary OD and new-to-market linear scale lengths ranging from 9-195 mm.

The solution accounts for what Celera Motion says is the largest source of angular error, eccentricity, caused by off-center scale mounting and bearing runout. Aura’s built-in compensation algorithm is designed to eliminate the need for a second encoder often used to correct for ecentricity.

According to the company, Aura is well-suited for high-volume OEM applications including surgical robots; cobots, robot joints and grippers; exoskeleton and wearables; and the semiconductor industry.
