E9 miniature rotary encoder measures 0.866 inch in diameter and 0.81 inch in length, and is available with resolution of up to 512 lines per revolution. A proprietary CMOS ASIC performs all electronic functions in the encoder, including signal detection, conditioning, and output. The detection circuitry uses an integrated sensor matrix and mask, which provides quadrature and index signal phasing. E9's rugged modified-polymer code disc exhibits dimensional stability over an operating temperature range of -40 to 100C.
