Fanuc A860-0315-T103 Encoder. This red pulse coder is a 3000 pulse incremental feedback unit used on AC servo motors. With an alternative order part number from Fanuc of: A290-0561-V506.
DNC offer new and used refurbished encoders with warranty on an exchange basis (assuming in stock). Testing, fault diagnosis, rebuild and repair of these A8600315T103 is possible, dependent on fault. An alternative solution maybe available by using a earlier generation of incremental encoder and a Fanuc AC servo motor that has the different end shaft to fit it. If in doubt contact DNC for more details, warranty and prices.
