3.2 Nm / 1 kW HD servo in the 1FK2 family
1FK2104-6AF00-1SA0 is a SIMOTICS S-1FK2 HD synchronous servo from the 1FK2 servomotor family, dimensioned for the SINAMICS S210 drive platform and rated M0=3.2 Nm with a 1 kW continuous output at 3000 rpm on the 380-480 V supply, or 0.5 kW at 1500 rpm when fed from the 200-240 V rail. The dual-voltage rating is the part's most consequential electrical spec: an integrator pairing this motor with a SINAMICS S210 must select the drive's line input module and DC-bus configuration to match whichever supply band the cabinet feed delivers, because the same winding delivers 1 kW at 480 V but only 0.5 kW at 240 V. Feedback is an absolute encoder single-turn 22-bit (AS22DQC) over the OCC interface, with power and signals carried through a rotatable M17 plug — a configuration typical for S210-driven high-dynamic axes where the cabinet-side cabling must swivel to follow the machine's cable chain. For deployment, the IP64 housing and D19x40 mm shaft with feather key suit machine builders who need a sealed servo for general industrial enclosures — protected against splash and dust ingress, but not rated for the washdown or food-grade zones where IP65/IP67 would be required.
Make-to-order commercial class — quoting posture
Per the manufacturer's product class, 1FK2104-6AF00-1SA0 falls under class C — products manufactured / produced to order, which cannot be reused or re-utilized or returned against credit — so the line is built to the BOM quantity and is not held as saleable shelf stock. Export control flags AL:N and ECCN:N_CNDU indicate no licence trigger for typical industrial destinations, which matters to a public-sector tender where the supply chain traceability line on the compliance schedule has to be defensible.
Substance compliance evidence for tender schedules
For a tender or audit, the substance-compliance trail shows RoHS conformity since 01-07-06, REACH Art. 33 information on file per the manufacturer's current candidate list, and packaging shipped at 1-piece quantity unit in a 452.00 x 250.00 x 267.00 mm pack. Group Code R220 and Product Group 9021 are the Siemens-internal classification keys carried on the product record — useful for storeroom keepers matching the part against the OEM catalogue hierarchy when raising an internal MRO order or reconciliation ticket.
