US Digital Motor Encoder E3 Description The US Digital E3 motor encoder mounts directly to a motor or other rotating shaft. This optical encoder features a rugged, glass-filled polymer housing and is designed for easy installation and removal.
The E3 optical rotary encoder contains a precision machined aluminum hub with a specially patterned Mylar disk. This disk, in combination with our proprietary optical encoder module, creates a system that is highly tolerant to mechanical misalignment.
The E3 is available with two base configurations and three cover styles, which allow it to fit a wide range of applications. The output for this optical rotary encoder is single-ended. If your application requires a differential output (due to needing a cable over 10 feet or is located in an electrically noisy environment) you can either add a PC4 / PC5 differential line driver or check out our E6
This incremental encoder is designed for use with a high-retention connector. After making each selection in the Product Configurator, compatible cables and connectors will be displayed below and must be purchased separately.
