What the order code covers
The 1FK7042-2AF71-1TB0 is a 1FK7 COMPACT SYNCHRONOUS MOTOR from Siemens in the Servo Motors class, a brushless servo drive element paired with the SINAMICS S120 / SIMOTION family for high-dynamic positioning axes.
Lifecycle read: eol_hot and what that means for sourcing
Lifecycle stage is recorded as eol_hot, so the part is in the late tail of factory availability — production is winding down while service spares and broker-channel inventory still move. For a line-down call, the practical path is independent distribution: quote against the BOM against an RFQ and let availability be confirmed at quote time, since stock and lead time are lot-specific once the factory tail runs dry.
Where this class of motor drops into a machine
Compact synchronous servos in this Siemens range typically drive feed axes, rotary tables, and small-format gantries where dynamic response and a clean encoder feedback path to a SINAMICS drive matter more than raw stall torque.
