S16 Product Description

The S16 16mm micro-optical shaft encoder is designed to provide A, B, and Index digital quadrature signals for high volume, restricted space applications.

Three shaft torque options are available:

Default (-D): sleeve bushing with higher damping for human interface applications.
Ball bearing (-B): miniature precision ball bearings suitable for high-speed applications.
Light static drag (-N): sleeve bushing with lower damping for low-speed applications.

The S16 series encoder is connected using a 5-conductor, polarized, 0.8mm pitch connector (Hirose part number DF52-5P-0.8C). The mating cable (see the Cables web page) is not included and is available separately.
