A Miniature Surface Mount Reflective Optical Shaft Encoder
The HEDR-8000 Series encoders provide two-channel medium-resolution encoding performance in a very small SO-8 plastic package. Their small size, reflective operation, and low cost enable customers to design them into applications that were impossible for earlier encoders, such as feedback sensing for the miniature motors used in copiers, cameras, vending machines, and card readers.
