‘Ground-breaking’ encoders handle extreme conditions
Published:  12 April, 2023

Celera Motion has announced a range of “ground-breaking” absolute inductive encoders that deliver “next-level” accuracy angle measurements in demanding conditions – dusty, dirty and wet environments, or where high shocks and vibrations are present – that would not be suitable for conventional optical encoders. The Field Calibration IncOders are aimed at motion control applications and position feedback in robotics.

The sensors are based on an inductive sensing method with an accuracy of up to 10 arc-seconds. Their claimed benefits include:
• the ability to calibrate the encoder in situ, for the highest possible accuracy;
• a low-profile shape with a large bore, making the sensors compact, light weight and easy to install;
• a rugged construction that resists dust, dirt, oil, water and other contaminants;
• the ability to generate calibration tables and store calibration data in on-board electronics by communicating via a bespoke serial interface;
• a choice of sizes (37–300mm) and mounting formats;
• a duplex mechanical format that provides electrical redundancy, for enhanced safety; and
• immunity to external magnetic fields.

“Our new Field Calibration IncOder provides the best of both worlds: the superior accuracy of optical encoders, with the robustness of our inductive IncOder series,” says Swapnil Mane, Celera’s vice-president of product management and marketing. “And it achieves this in a low-profile, inductive sensor package. By enabling customers to store calibration data within IncOder after installation, a gearshift in accuracy performance is made possible.”

The sensors are configurable in terms of mounting format, connections, supply voltage, single- or multi-turn outputs, and support for digital protocols including BiSS-C, SSI, SPI, ABZ and asynchronous serial outputs.

The new angle sensors combine optical encoder accuracy with inductive robustness, allowing precision measurements in challenging environments
