microsecond. A programmable ABZ generator with FlexCount® quadrature resolution easily adapts to any controller and provides sharp edges for excellent control quality.

 

Thanks to auto-calibration and eccentricity compensation, encoder systems with the iC-RT2624 easily achieve an angular accuracy of less than 0.01°. On-chip calibration can be performed via the BiSS and SPI serial interfaces or at the push of a button. This simplifies the production of encoder systems and saves time when commissioning modular kit encoders. The dimensions of the code disc can be freely adjusted with a FlexCode® design starting at an outer diameter of 20 mm. This allows compact motor feedback and larger hollow shaft encoders to be developed with the same sensor.

The iC-RT2624 can be operated within 3.0 V to 5.5 V and is sensitive to blue, red, and infrared light. The LED control integrated in the chip adjusts the illumination for an optimal operating point. The encoder SoC is suitable for an operating temperature range of -40 °C to 125 °C. A comprehensive monitoring and diagnostic architecture constantly checks the operating conditions. For instance, a digital contrast measurement detects when condensation or precipitation from outgassing ball bearing grease impairs the optical projection before the angle detection is critically disrupted – for permanent condition monitoring.
