Omnicoder
®
Model H25
®
The Omnicoder features a patented dynamic encoder resolution capability that allows users to easily
program the encoder resolution to any value between 1 and 10,000 counts per turn. Packaged in
BEI’s flagship Model H25
®
incremental encoder, the Omnicoder allows for virtually unlimited resolution
variations.
Using the simple programming interface software and USB interface cable, users can program
the encoder resolution on site as needed. In the software, type the encoder resolution and click
‘Program’. A new resolution is now programmed. It’s that easy!
With the Omnicoder, resolution can be programmed and reprogrammed at any time by the user.
For users with multiple resolution requirements, Omnicoders can be kept in stock and programmed
as needed.
