iC-Haus has optimized the incremental scanners of the 'iC-PT H-Series' for high resolutions especially for blue light and has given the integration platform for such single-chip encoders the brand name Encoder blue. The encoder sensors in the series combine optical scanning with interpolating signal evaluation. A 5 mm × 5 mm 'optoQFN' with a flat window is used. Thanks to the optimized phased array structure of the photochips, a minimum scanning area of just 1.9 mm × 3.1 mm is sufficient to generate 10,000 pulses from a code disc with a diameter of 26 mm, for example. According to the manufacturer, the blue light increases the contrast with less noise, while the improved efficiency reduces the power consumption in the optical system. The components deliver low-jitter encoder quadrature signals with index via 4 mA push-pull drivers in single, double and quadruple resolution for precise motor control. At the same time, the Hall sensors normally used for commutation are replaced by three additional integrated scanning tracks. The code disk determines the desired signal and can be easily adapted to the required number of motor poles. The index linkage and the resolution are set by pin. Output frequencies of up to 1.6 MHz are permissible.
