Optical Incremental Encoders

Series 920, a family of optical incremental encoders, is designed for industrial grade- applications that require high resolution and accuracy. The compact units are 2" x 1.5" long and generate up to 36,000 quadrature cycles per revolution. The Series is available as a conventional shaft encoder, or in a hollow shaft version. Features include single board, surface mount electronics for reliability; RS-422 differential line driver output for noise immunity; sealed ABEC 7 bearings for contamination resistance; and IP66 sealing for harsh environments. A once-per-rev signal is standard.
