Reading the order code on this small-frame servo
The 1FK7042-2AF71-1CB0-Z carries as its descriptive identity the SIMOTICS S short stack from Siemens — a compact synchronous servo sized for the lower end of the SIMOTICS S frame range, where it pairs with a SINAMICS drive on a positioning axis or a small-format machine tool feed.
Why EOL hot changes the procurement posture
The lifecycle stage is recorded as EOL hot — a Siemens phase meaning the part has been announced for discontinuation but the factory is still shipping against committed orders, with the channel shifting toward independent distribution and surplus as the wind-down progresses. For an integrator who already has this code on a drawing, that translates into a shorter runway than the original design assumed: any new machine build should be re-engineered to the current SIMOTICS S successor before the next reorder, while field spares for installed fleets are the realistic demand the part will serve from here on. Spare replenishment on an EOL hot part is the main buying question it answers now — not a new-machine design-in, which is the typical framing this part number used to draw when it was active.
