iC-PZ
High-Resolution Reflective Absolute Encoder
- Reflective, compact, high-resolution, absolute encoder iC
- iC-PZ0974 and iC-PZ2656 for reflective code discs up to ø45 mm
- iC-PZ205 for reflective code discs > ø45 mm and linear scales (max. 6.71m)
Description
The iC-PZ is a complete lensless optical reflective absolute encoder IC. With its integrated blue LED and interpolator, the iC-PZ provides a high-resolution single-chip absolute linear or rotary encoder solution. Independently configurable BiSS/SSI, ABZ, UVW, SPI, and analog Sin/Cos outputs may be used singly or in combination to provide a highly flexible system. FlexCount® and FlexCode® allow arbitrary ABZ resolution and arbitrary code disc diameter.
