What the listing actually is
The Siemens 1FK70422AF711FG2 is a synchronous servo from the 1FK7-CT family rated at 3 NM — a compact brushless servo typically paired with a SINAMICS drive on a tight robot cell or pick-and-place axis where the cycle budget is the constraint, not the stall torque.
Lifecycle status — read this first
No official successor or pin-compatible cross-reference appears on the record for this code, so any substitution has to be validated against the SINAMICS drive firmware and the mechanical shaft interface rather than assumed from a family listing.
Sourcing posture for a hot-EOL servo
For a hot-EOL Siemens servo like this, the realistic channel is quoted-to-order against an RFQ — independent distribution and factory-traceable surplus, with lead time and lot quantity confirmed at quote, never assumed from a listing.
