Broadcom AR35-L80 family reflective linear encoders

The Broadcom® AR35-L80 series is a reflective encoder, designed for linear scale applications. It features an incremental-mode output and user-programmable resolution. The AR35-L80 works in combination with the code strip, with a window pitch of 80 µm and the full code length of 40.96 mm. There are 5 programmable resolution outputs, offering a quadrature output resolution ranging from 20 µm to 1.25 µm pitch. Broadcom's patented Reflective Optical Encoding Theory, the AR35 series offers high accuracy with correction, which is unattainable with magnetic encoders.
