Incremental Encoders

Incremental Encoders, and, in particular, incremental optical encoders, are the most popular choice of sensors in applications where mechanical motion must be processed into digital information. Compared with alternate technologies (such as resolvers, tachometers, etc.), optical encoders represent the best combination of accuracy, resolution, reliability, ruggedness, ease of use, value and variety of solutions in the industry. For these reasons, optical encoders are the overwhelming choice where speed, rate, velocity, distance, position, or direction must be accurately and economically measured. Resolutions up to 30,000 counts per revolution (CPR) and operating temperatures up to 120° C (248° F) are just some of features.

Incremental encoders are broken into three model groups, OEM Models, Shaft Models, and Bore Models. Each model group has unique physical styles which include many mounting options, case styles, and useful features.

Absolute Encoders

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.
