SIMOTICS S-1FK2 HD — 2.4 Nm stall, 0.75 kW at 3000 rpm
The 1FK2104-5AF01-1SB0: A SIMOTICS S-1FK2 HD brushless servo motor with a stall torque M0 of 2.4 Nm and rated power P_N of 0.75 kW at n_N of 3000 rpm when supplied from a 380-480 V drive bus, with a derated 0.375 kW at 1500 rpm on a 200-240 V bus — meaning the same frame covers both the 230 V and the 400 V class SINAMICS topologies without a motor swap. Feedback is an absolute single-turn 22-bit encoder (AS22DQC) wired through a DRIVE-CLiQ plug M17, so commissioning lands position on the drive at first power-up without an incremental homing run — a single cable carries encoder data and motor identity into the SINAMICS control cabinet. IP65 sealing on the body and a D19x40 mm keyed shaft suit the motor to factory-floor mounting inside an enclosure-adjacent machine frame, where coolant splash and dust are daily conditions rather than washdown immersion.
Build-to-order per piece, Group R220 product family 9021
Listed product class is build-to-order per the manufacturer's category C — units are produced per order quantity, not held as resellable shelf stock, which is consistent with Siemens' configured servo-motor supply model. Group Code R220 / Product Group 9021 place the line inside the Siemens drive-systems product numbering; this is the identifier to quote when the RFQ crosses into the manufacturer's order-management tooling. Single-piece Quantity Unit and a packaging footprint of 452 x 250 x 267 mm determine crating and pallet math at the receiving dock rather than the panel-side wiring choice.
RoHS compliance since 2006, REACH Art. 33 disclosure
RoHS substance-restriction compliance dates to 01-07-06, predating the EU RoHS recast scope and giving long-standing admissibility into EU equipment builds without a substance-exemption argument. REACH Article 33 disclosure is published against the current candidate list, so downstream integrators receive the SVHC communication the regulation requires when an article exceeds the 0.1 % w/w threshold.
Active production status
Lifecycle stage is current and the product status is Active — the part is in continuing production under the listed order code, so the BOM line does not need a substitute designation or a last-time-buy timestamp yet.
