What this servo is and where it bolts in
The 1FK7042-5AF71-1KB3 is a Siemens 1FK7-series servo motor from the Servo Motors line, the compact high-dynamic family typically paired with SINAMICS S110/S120 drive line-ups on packaging, converting, and pick-and-place machinery.
Lifecycle read — what eol_hot means on this code
The lifecycle stage recorded for this order code is eol_hot — Siemens has flagged the variant as approaching discontinuation, with last-time-buy typically taken on the OEM side and remaining stock moving through independent channels; the part is not pulled from sale outright, but new factory quantity is not being replenished at the original rate. For a buyer with a live BOM line this is the signal to lock in the quantities still in circulation through parallel and independent supply rather than wait for factory resumption that will not arrive — genuine Siemens stock carries the same nameplate and resolver stack regardless of which authorized region it ships from, but the manufacturer warranty stays tied to the region of original channel sale.
Sourcing posture for this code
Volume pricing and the available lot count are quoted against the RFQ at submission; there is no standing inventory figure published and no immediacy claim — buyers comparing parallel quotes across regions should match apples-to-apples on warranty geofencing rather than headline unit price, since the manufacturer warranty follows the original channel region.
