New Original FANUC A860-2070-T321 CNC Servo Pulse Coder Encoder<\/h1>\n

1. Product Overview<\/h2>\n

The FANUC A860-2070-T321 is a \u03b2iA1000 rotary pulse coder designed for FANUC Beta i series AC servo motors. It adopts optical rotary encoding structure to convert motor rotary motion into digital position and speed feedback signals. The encoder establishes closed-loop motion control with FANUC servo amplifiers and CNC controllers. Widely deployed on CNC lathes, machining centers, automated production equipment and industrial robot joint motors to guarantee precise axis positioning and stable dynamic operation. The supplied unit is brand-new original genuine FANUC product manufactured in Japan.<\/p>\n
