Broadcom AR18 + AR35 SERIES programmable absolute encoders

AR18 + AR35 Series are miniature Absolute Encoders ASIC designed to cater for the growing demand on the space constraint application

AR18 + AR35 Series are miniature Absolute Encoders ASIC designed to cater for the growing demand on the space constraint application. The AR18 encoder is designed for an overall diameter of 18 mm and offers user-programmable resolution ranging from 17,19, and 21 bit single-turn absolute output, while AR35 is designed for an overall diameter of 35 mm and offers 17 and 21 bits single-turn absolute output. Both, AR18 + AR35 series provide the incremental ABI and UVW in differential mode. Both come with a recommended high temperature range of –40...+115°C suitable for most industrial applications.
