Innovative dual inductor rotating position sensor from ON Semiconductor

     ON Semiconductor, a leader in smart power and smart sensing technology, has introduced an innovative dual-inductance rotating position sensor, the NCS32100, which convincingly offers high speed and precision. The NCS32100 uses a new patented method for inductive position sensing, making it ideal for deploying fast moving and industrial robot applications.

     Although the characteristics of inductive encoders make them very attractive for industrial applications, use cases have historically been limited to applications with low RPM and no high accuracy required. Drawing ON more than 20 years of expertise in designing inductive sensors, ON Semiconductor combines the reliability of inductive encoders with the high precision and high speed typically found in mid - to high-end optical encoders. Enables the NCS32100 (38mm sensor) to provide +/-50 arcseconds accuracy at 6,000 RPM. The NCS32100 supports speeds up to 100,000RPM without sacrificing some accuracy.

     "The NCS32100 uses firmware that outputs absolute position and speed directly and comes pre-installed in its integrated microcontroller, providing a simple 'plug and play' solution," said Michel De Mey, vice President of ON Semiconductor's Industrial Solutions division. "The integration of the NCS32100 significantly reduces design time and the need for the number of external components, speeding time to market for a more compact and efficient design."

     Several key characteristics of inductive sensors make them ideal for industrial applications. Dust, oil, and temperature and humidity in the environment have little impact on their accuracy. The NCS32100 device also has an integrated self-calibration program to resolve mechanical misalignment of the sensor. The high degree of configurability is available for a variety of printed circuit board sensor designs, enabling Oems to configure and differentiate their solutions. The integrated MCU contains non-volatile flash memory and a configurable interface to communicate with the main processor.
