What 1FK2104-6AF01-0SB0 delivers on the line
The 1FK2104-6AF01-0SB0 is a SIMOTICS S-1FK2 HD servo motor sized for the SINAMICS S120 drive platform — 3.2 Nm stall torque, 1 kW rated at 3000 rpm on a 380-480 V bus, with a 0.5 kW / 1500 rpm operating point available on a 200-240 V bus where the cabinet is built around 230 V supplies. Feedback is a 22-bit single-turn absolute encoder (AS22DQC) returned over a DRIVE-CLiQ M17 plug — the same digital service channel used across the SINAMICS family, so commissioning and topology auto-recognition work the moment the cable seats. The IP65 housing, cylindrical D19x40 mm shaft, and M17 power connector fit the standard 1FK2 mounting footprint for food-and-bev packaging, small-format assembly, and pick-and-place cells where the motor sits outside the cabinet.
Sourcing reality — built-to-order, active, single SKU
Lifecycle status is recorded as Active — production is current, so the BOM line stays open without a last-time-buy flag. The product class is C — built-to-order, non-returnable, and not re-usable as a stock credit — which means each unit is configured and built against the order rather than pulled from a finished-goods shelf. RoHS compliance has been on file since 01-07-06 and REACH Article 33 candidate-list information is published through the standard Siemens reach information channel; export classification is AL:N / ECCN:N_CNDU, so no export-licence gate applies for routine industrial shipments. Inbound packaging is a single-piece shipper at 452 x 250 x 267 mm and 1 Piece per Quantity Unit — one motor per carton is the default, which has to be reflected in any de-tray or repack planning at receiving.
Procurement intake — codes, family, where it sits
ERP intake should key on Group Code R220 and Product Group 9021 — both are the Siemens commodity buckets used for 1FK2 servomotors tied to SINAMICS S120, so the PO line and the manufacturer's product records reconcile cleanly when the codes match. Family context is 1FK2 servomotors for SINAMICS S120 — the HD (high-dynamic) variant sits in the compact end of the 1FK2 line, which matters when sizing adjacent frames against the same drive line.
