The iC-PT H series Encoder blue encoder chips combine optimized scanning and signal interpolation in a flat 5 x 5 mm² optoQFN package with a plane window. Because of the optimized phased-array structure of the opto-chips, a minimal scanning area of 1.9 mm x 3.1 mm is sufficient to generate 10,000 pulses per revolution using a 26-mm-dia. code disc. The devices generate low-jitter encoder quadrature signals with index via 4-mA push-pull drivers in single, double and four-fold resolution for precise motor regulation.
