AS37-H39B

AS37-H39B Series 39-Bit Battery Backup Multi-Turn Absolute Encoder Data Sheet Introduction The AS37-H39B 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 AS37-H39B 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 AS37-H39B 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. 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. The AS37-H39B series is also compliant with IP40 per IEC 60529 standard. The key advantage of the AS...
