iC-Haus

At SPS 2019 (hall 4A, booth 136) in Nuremberg (November 26-28), iC-Haus presents its latest generation of integrated high-resolution optical-reflective absolute encoders. The iC-PZ Series is said to set new standards in flexibility and miniaturisation.

iC-Haus will debut a 26-bit encoder signal processor iC-TW29 with integrated EEPROM at the SPS exhibition in Nuremberg (November 26-28). It is used for the evaluation of magnetic and optical sensors that generate sine and cosine signals.

iC-Haus has expanded its product family in the field of integrated system solutions for sensor-sided BiSS and SSI communication, including absolute encoder applications. The field-sided RS422 transceiver for clock reception and data signal is designed for typical industrial point-to-point encoder applications to enable physical interface compatibility for many drive systems and controllers on the sensor side.

Recently released by iC-Haus, the iC-MH16 is a one-chip solution for magnetic sensor applications in fast motor control units. Combined with a diametrically magnetized permanent magnet, the tiny device can be used to create a robust, universal encoder for motor commutation and positioning. The chip contains a Hall sensor array with signal amplification control, a FlexCount interpolator delivering incremental (ABZ) and latency-free commutation (UVW) signals, integrated RS422 line drivers, and a serial SSI/BiSS interface.

Resolution, signal amplitude, harmonic distortion, and jitter performance of incremental and absolute encoders can be improved by the use of blue light, with its shorter wavelength and penetration. Blue light causes less diffraction at the same slot width compared to higher wavelengths, thus resulting in sharper imaging.
