AS38-H39E Series 39-Bit Energy-Harvesting Multi-Turn Absolute Encoder Data Sheet Introduction The AS38-H39E series encoder is a high-resolution optical absolute encoder produced by Broadcom®, which offers 23-bit single-turn and 16-bit multi-turn counts, hence a combined 39-bit high resolution. The AS38-H39E series encoder is a house encoder consisting of a patterned disk, a light source, and photosensitive elements to translate the mechanical motion into electrical signal. The AS38-H39E series encoder has a built-in communication protocol that is supported by a full-duplex or half-duplex line transmissions drive, offering good noise immunity for more robust transmission of data up to 10 Mb/s in harsh industrial application.
