Description
The Fanuc A860-2020-T361 is a high-precision Alpha iI64 incremental pulse coder designed for closed-loop feedback in Fanuc AC Servo Motor systems. This original engineering component serves as the primary velocity and position feedback mechanism, ensuring synchronized motion control and high-speed stability in CNC machining environments.

SYSTEM COMPATIBILITY
This encoder is compatible with Fanuc Alpha i and Alpha iS series servo motors. It is frequently integrated with motor models including but not limited to: αiF 4/4000, αiF 8/3000, and αiS 2/5000. It ensures seamless technical compatibility with Fanuc 16i, 18i, 21i, and 30i/31i/32i Series CNC Control units.
INDUSTRIAL APPLICATION
The A860-2020-T361 is critical in high-accuracy milling and turning centers where thermal stability and signal integrity are paramount. In scenarios involving high-speed contouring, the 64K resolution allows the CNC drive to perform micro-interpolation, reducing surface roughness and eliminating vibration during rapid traverse. Its robust serial interface minimizes electromagnetic interference (EMI) in dense industrial electrical cabinets.
MAINTENANCE AND LIFECYCLE
As an original Fanuc spare part, this unit guarantees the restoration of factory-standard positioning accuracy. Replacing a degraded encoder with this original engineering unit reduces machine downtime and prevents ‘Soft Disconnect’ or ‘Serial Link’ alarms (Fanuc Alarm 300, 368, or 385). Standard lead time applies for global distribution to ensure rapid restoration of manufacturing capacity.
