1FL2104-2AF01-1HC0 in the SIMOTICS S-1FL2 line
The Siemens 1FL2104-2AF01-1HC0 is a SIMOTICS S-1FL2 low-inertia servomotor from the 1FL2 family, sized for direct pairing with a SINAMICS S200 drive. The 400 V 3AC supply and 0.75 kW rated power (Pn=0.75 kW) put it in the small-frame class where the drive converter handles the commutation and the motor is the torque-producing element of the axis. Rated speed is 3000 rpm (Nn=3000 rpm) with both stall and rated torque at 2.4 Nm (M0=2.4 Nm; Mn=2.4 Nm) — a flat torque profile from standstill to base speed, which suits point-to-point motion, indexing, and small conveyor or pick-and-place axes where the motor rarely runs above base. The shaft height 40 mm frame, hybrid connector, 17-bit single-turn absolute encoder, keyed shaft (tolerance N), and the oil-sealed IP65 housing are all part of one configured order code — nothing here is an add-on accessory, so the BOM line matches what arrives on the dock.
What the ratings drive in the panel
At 0.75 kW with a 2.4 Nm continuous torque envelope and 3000 rpm base speed, the axis delivers its mechanical work well inside the small-frame thermal budget — no external fan, no forced-air kit, so the cabinet layout stays compact and the motor runs on its natural convection through the IP65 housing. The hybrid connector (not an MS-style military round connector) carries both power and the 17-bit encoder feedback in one plug, which shortens commissioning time and removes the second-cable alignment error that a separate feedback harness can introduce. The seal is the wet-end barrier; the housing itself is dust-tight and jet-resistant. Matching drive is the SINAMICS S200 family, so commissioning should be set to that drive variant. The encoder (17-bit) and the motor ID are recognised on first connection and the auto-tuning routine picks the right current loop and inertia ratio from there.
Configuration in the order code
Configuration decoding: 2AF01 in the code marks the 40 mm shaft height with the 0.75 kW windings; 1HC0 specifies the hybrid connector, 17-bit encoder, keyed shaft with N tolerance, no holding brake, and IP65 with oil seal — meaning the brake option has been deliberately omitted from the BOM line, which is normal for axes that don't need a fail-safe hold at rest. Holding brake absence is the only configuration decision worth flagging: any application requiring vertical-axis hold or a controlled stop on power loss must spec a brake option motor instead, since retrofitting a brake onto this shaft extension is not a supported field change.
Lifecycle and quoting posture
Lifecycle stage is listed as current and the part is a made-to-order item in product class C — produced to a specific configuration, non-returnable, non-reusable across other orders — so volume builds are quoted against the BOM quantity with the standard Siemens build lead time, not pulled from shelf stock. Group code R220 and product group X0DK are the Siemens-internal classification keys that procurement and ERP systems use to route the order to the right production line and to confirm pricing against the active price book. Compliance posture: RoHS conformity since 01-01-18, REACH Art. 33 information obligation flagged, and export classification AL:N / ECCN:N (no special export licence required). Reach candidate-list substance information is provided on demand — the documented EU compliance trail is in place. Packaging is single-piece (Quantity Unit 1 Piece) in a 382 x 222 x 240 mm pack, so single-unit spares and small panel-builds ship without pallet breakup.
