New Original FANUC A860-2070-T371 CNC Servo Pulse Coder<\/h1>\n

1. Product Overview<\/h2>\n

The FANUC A860-2070-T371 is a \u03b2iA1000 rotary pulse coder specially designed for FANUC \u03b2i series AC servo motors. It converts mechanical rotary motion of the motor shaft into digital speed and position feedback signals via an optical encoding system. Working cooperatively with FANUC servo amplifiers and CNC controllers, it forms a closed-loop motion control system. This encoder is widely equipped on CNC lathes, machining centers, automated production machinery and handling equipment to achieve precise axis positioning and stable dynamic operation. The supplied unit is brand-new original genuine FANUC product made in Japan.<\/p>\n
