DNC offer new and used refurbished encoders with warranty on an exchange basis (assuming in stock). Testing, fault diagnosis, rebuild and repair of these A8600304T111 is possible, dependent on fault. An alternative solution maybe available by using a later generation of incremental encoder and a motor that has the different shaft to fit it. If in doubt contact DNC for more details, warranty and prices.
