Headline rating and machine role
The Siemens 1FK2104-5AF10-0MB0 is a SIMOTICS S-1FK2 HD synchronous servo from the 1FK2 family targeted at SINAMICS S120 drive systems, rated PN = 0.75 kW at nN = 3000 rpm on a 380–480 V bus and PN = 0.375 kW at nN = 1500 rpm on a 200–240 V bus, with a static torque M0 = 2.4 Nm and an integrated holding brake. The shaft is a plain cylindrical D19×40 mm profile and the feedback is a 22-bit single-turn plus 12-bit multiturn absolute encoder (AM22DQC), wired through DRIVE-CLiQ and power connectors both sized M17 — so the cabinet-side harness uses the same connector family and avoids mixed-cable looms when the drive is a SINAMICS S120. IP64 protection on the motor body means it tolerates dust ingress and splashed water but is not rated for hose-down washdown environments — for hygienic or food-grade lines, an IP65/67 variant from the same 1FK2 family should be specified instead.
Lifecycle and sourcing posture
The product class is C — built to order against the order quantity, which cannot be reused or returned for credit. For tender and audit purposes, every delivery is a unique build rather than shelf stock; specification must be locked before the order is released and the packaging footprint of 452 × 250 × 267 mm reflects that one-piece build. RoHS compliance has been in force since 01-07-06 and REACH Art. 33 candidate-list information is provided as Reach Information — both are evidenced at the article level rather than inferred from series literature, which is the figure that survives a procurement audit.
Series context and procurement framing
The order code belongs to Group Code R220 / Product Group 9021 inside the Siemens classification scheme — the identifiers a tender response quotes when the line item must be traced back to its commercial grouping and audit trail, not just the catalog type. Export control is AL:N with ECCN N_CNDU, meaning the part does not trigger a dual-use export licence for the listed destination regimes. For a municipal water-authority framework or similar audit-driven award, this line is straightforwardly defensible without an ECCN gate.
