Broadcom AS37-H39B 39-Bit Battery Backup Multi-Turn Absolute Encoders provide a 23-bit single-turn and 16-bit multi-turn count, creating a combined 39-bit resolution. The higher resolution on these devices, coupled with higher measurement accuracy, results in better speed ripple control. Broadcom AS37-H39B encoders offer excellent noise immunity for robust transmission of data up to 10Mb/s in harsh industrial applications, provided by the built-in communication protocol. Multi-turn tracking utilizes battery backup technology while gear wear-out is eliminated through gearless multi-turn counting, both benefits of this series.
