Description

iC-Haus iC-RZ Series

The iC-Haus iC-RZ Series is an advanced absolute optical encoder IC series for functional safety applications. It provides two autonomous channels. The control channel (CC) and the safety channel (SC) both utilize high-definition phased-array photosensors to read an incremental track. This generates sin/cos signals that are used to increase the resolution via the integrated interpolator. Additionally, a sin/cos signal can be output for use by an external interpolation IC for even higher resolutions.
