Product details

Servo motor on a hot phase-out

The Siemens 1FK7042-5AF71-1DH0 is a SIMOTICS S-family synchronous servo motor in the 1FK7 frame, classified in this catalog as a Servo Motor under Motors & Motor Controls.

Why an eol_hot motor still ends up on an RFQ

A servo in the 1FK7042 frame typically drives a positioning axis on a packaging, converting, or assembly line where the downstream mechanics, gearbox, and connector pinout are already qualified against this exact winding and encoder combination.

Frequently asked questions

Who supplies 1FK7042-5AF71-1DH0 and how is it quoted for volume purchases?

Volume supply for this eol_hot servo runs through independent industrial-automation distribution: each quote is built against the BOM quantity with current pricing and lot-traceable availability confirmed at RFQ time — no standing-stock claim is made on a phase-out motor.

Will 1FK7042-5AF71-1DH0 drop into a panel that was specified around 1FK7042-5AF21-1UA0 without rewiring?

Not as a straight pin-for-pin swap. Both motors share the 1FK7042 frame and category, but the 1FK7042-5AF21-1UA0 peer lists 4.54 kg versus this motor's 5.44 kg, indicating a different winding and encoder build — the feedback cable, brake, and drive parameter set need re-verification before a no-rewire substitution is assumed.
