Description

This series of optical encoder iCs features monolithically integrated photosensors. Precision sine/cosine signals are output for a high-resolution interpolation by subsequent devices, such as iC-MNF, resolving a singleturn position with 23 bits and higher. Output amplitudes of several hundred millivolts are achieved at low illumination levels, saving LED current for durability. As a typical Nonius scale for iC-PNE repeats 8 times per turn, 4 sector tracks are scanned digitally by additional photosensors. This section runs independently on a lower supply voltage with extremely low power consumption, allowing battery operation. The typical application of iC-PNE devices are absolute position encoders for motion control and drive applications.
