Broadcom AR35-T25 25-bit absolute encoder

The Broadcom® AR35-T25 Hollow Through series is a miniature absolute encoder, designed to cater to the growing demand of space-constrained applications. The AR35-T25 series provides an absolute mode of reading in serial communication output and incremental ABI and UVW in differential mode. It has an overall diameter of 35 mm with the maximum axial through-hole of 9.5 mm for through-shaft motor and axial cabling applications. Employing Broadcom's patented Reflective Optical Encoding Theory, the AR35 series offers high accuracy with correction, which is unattainable with magnetic encoders.
