AS38-H39E-B13S

AS38-H39E-B13S is a Broadcom® AS38-H39E series 39bit energy-harvesting multi-turn high resolution optical absolute encoder. It offers 23bit single turn and 16-bit multi-turn counts, hence a combined 39bit high resolution. It is a house encoder consisting of a patterned disk, a light source, and photosensitive elements to translate the mechanical motion into an electrical signal. It has a built-in communication protocol that is supported by a full-duplex or half-duplex line transmission drive, offering good noise immunity for more robust transmission of data up to 10Mb/s in harsh industrial application. Because the product is intended for industrial application, ESD protection circuitry has been designed in to achieve Class 3 ESD immunity per IEC -61000-4-2 standard. It is also compliant with IP50 per IEC60529 standard. Application includes robotics, factory automation, linear positioning system, CNC machine tool, medical and lab equipment.
