The FANUC A860-0392-V160 (also known as BZ built-in spindle sensor pick-up assembly) is an original FANUC rotary pulse coder dedicated for FANUC AC spindle motors. It collects real-time rotational speed, spindle position and rotation direction signals, and transmits pulse feedback data to the CNC control system.
The CNC system relies on these feedback signals to realize spindle orientation, rigid tapping, constant surface speed control and other precision functions. It is an essential feedback component for high-precision CNC machine tools, widely used for spindle motor maintenance, spare parts replacement and equipment retrofitting of machining centers and CNC lathes.
