As with all of EPC's encoders, these absolute encoders
represent the best overall value available. Their simplified design make them
ideal, cost-effective solutions to many problems faced in motion control and in
industrial automation. They are particularly suited for applications where a device
is inactive for long periods of time or moves at a slow rate, such as flood gate
control, telescopes, cranes, valves, etc., and in machine tooling, printing, paper
making and many other industries.
Absolute encoders generate a unique binary
"word" output for each resolvable shaft position so that each shaft
position is fully determined. By using absolute position rather than incremental
count data, the shaft position is always known, even after power interruptions
or in the presence of electrical noise. System design can also be simplified because
there is no need to perform a reference cycle or return to home function to determine
the true machine position.
EPC offers single turn devices with resolutions
ranging from 8 bit (256 counts per rev) to 12 bit (4096 counts per rev). You can
choose from a variety of formats, including binary or gray code, and from a variety
of output types. Also available are innovative hollow bore models that extend
the application areas suitable for absolutes.
