What 1FK7064-7AF71-1AH3Z is on the line
The 1FK7064-7AF71-1AH3Z is a Siemens gearmotor in the SIMOTICS 1FK7 servo family — a brushless servo motor with an integrated gearbox used where a compact, precise speed-and-position package has to drive a machine section directly from the shaft. It sits in the Servo Motors category as a Gear Motor under Gear and Gearbox Components, so the unit ships as a single shaft-and-gear assembly rather than a bare servo plus separately mounted reducer.
Lifecycle stage: EOL/hot and what that means
With no official L*-cited successor on the ledger for this code, there is no documented drop-in replacement from Siemens in the 1FK7 family — a substitution question has to be answered against the application's shaft, feedback, and connector envelope, not against a named successor part.
