iC-Haus China - Optical Encoder iCs

Optical Encoder iCs

The Optical Encoder iCs utilize active photodiode arrays for incremental and absolute optical encoders.

The Optical Encoder portfolio ranges from simple photodiode arrays up to highly integrated System-On-Chip iCs, combining into one chip: opto sensors, signal conditioning and processing circuits, interpolation, parallel or serial interfaces, multiturn interfaces, controlled LED driver and other functions.

Standard code discs and reticles (when necessary) are also available for different resolution and size possibilities. Phased-Array technology products are also available, which do not require reticles on the chip.

Applications:

Motion control (position and speed)
Drive systems
Robotics
Optical encoders
