Its powerful interpolation circuit detects the angle of a code disc with 26-bit resolution. Thanks to contamination-tolerant scanning and high mounting tolerances, the iC-RT2624 is said to be ideal for housed and kit encoders. Precise, innovative, and flexible in application: that is the new System-on-Chip (SoC) for optical absolute encoders from iC-Haus. The iC-RT2624 has state-of-the-art photodetectors and robust, contamination-tolerant scanning. The microelectronics integrated in the compact 7 mm x 5 mm optoQFN package delivers accurate measurements within high mounting tolerances. The powerful interpolation circuit with filtering at the heart of the system reliably detects the angle of a 26 mm code disc with 26-bit resolution, even in demanding, dynamic applications. Digitised angle information is available to the BiSS, SSI, or SPI serial interfaces in less than one 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 iCRT2624 can 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. Another new feature is the programmable sin/cos generator, which can be set to 2n CPR (n = 0..15) regardless of the base resolution of the code disc. The native sin/cos resolution is simultaneously available for output and routed through a separate, safety-ready signal path. The integrated Absolute Data Interface (ADI) completes the diverse interfaces of this flexible sensor platform and is compatible with established multiturn sensors from iC-Haus, such as the battery-buffered iC-PVL, the gear scanner iC-MV, or energy harvesting systems with Wiegand wire. 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 https://www.ichaus.de/product/icSPS 2025 (Hall 7, Booth 370) Watlow, a global leader in industrial thermal systems, will present its latest intelligent control and power management technologies at SPS 2025 in Nuremberg. As part of its vision for the Factory of the Future, Watlow will demonstrate how its Edge Process Management (EPM) Data platform and PowerNode controller enable manufacturers to simplify control architectures, improve process efficiency, and achieve smarter, data-driven production. Central to Watlow’s vision for the Factory of the Future is a commitment to decarbonisation through the electrification of industrial heating. By replacing fossil fuel-based systems with advanced electric solutions, manufacturers can significantly reduce energy consumption and carbon emissions while enhancing process reliability and control. At the centre of Watlow’s stand, visitors will discover EPM Data, a cutting-edge, data-centric, and distributed platform that connects machines, people, and processes. By bringing intelligence to the edge, where information is generated, EPM Data empowers operators to make faster and better-informed decisions while maintaining robust data integrity and cybersecurity. EPM Data provides an integrated environment for data management and process visibility. With intuitive touchscreen HMIs, the platform supports real-time monitoring and control, helping manufacturers enhance efficiency and ensure compliance across regulated and industrial environments. Designed to support digital transformation, it combines modular I/O, a common configuration environment, and multiWatlow Showcases Edge Intelligence and Power Control Innovations at SPS
