US Digital E16 Motor Encoder Description

Restriction of Hazardous Substances

The E16 micro motor encoder is only 16 mm in diameter and mounts directly to a motor or other rotating shaft. This incremental encoder uses a specially patterned optical disk on a precision-machined aluminum hub. 

This disk, in combination with a custom detector, creates a system highly tolerant to mechanical misalignment. A push-on hub design and a robust, glass-filled polymer housing provide easy installation in space-limited applications.

The E16 optical rotary encoder offers 10 resolutions and compatibility with two shaft sizes (1.5 mm and 2.0 mm). It comes standard with a two-channel quadrature output with index.

This optical rotary encoder is designed for use with a polarized connector. After making each selection in the Product Configurator, compatible cables will be displayed below and must be purchased separately.

Please Note: Due to the E16's design, it is recommended for use as a one-time installation.
