E16 Micro Rotary Encoder Product Description

Restriction of Hazardous Substances

The E16 micro optical encoder is only 16 mm in diameter and is designed to provide A, B, and Index digital quadrature signals for high-volume, restricted space applications. The E16 utilizes an innovative, push-on encoder disk that accepts shaft diameters of 1.5 mm and 2 mm.

The E16 is designed to be a one-time installation miniature motor encoder, the base provides mounting holes for two M1.6--0.35 x 3 mm screws on a 10 mm bolt circle. The encoder cover is easily snapped onto the base and is laser marked with the connector pin-out.

The E16 series miniature encoder is connected using a 5-conductor, polarized, 0.8 mm pitch connector (Hirose part number DF52-5P-0.8C). When using the Configurator, compatible cables will be displayed below after the encoder is configured. Cables must be ordered separately. 

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