What 0.4 kW at 1.27 Nm actually buys you on this shaft
Siemens 1FL2203-4AF11-0HC0 is a SIMOTICS S-1FL2 low-inertia servomotor in the 1FL2 family, sized at 0.4 kW with a continuous stall and rated torque of 1.27 Nm and a rated speed of 3000 rpm off a 400 V 3AC supply, which puts it in the small-format end of the SINAMICS S200 motion axis — typically the auxiliary slide, indexing table, or feed axis on a packaging or assembly cell rather than the main spindle. The motor ships as a configured build rather than a stocked SKU — class C, made to order per the Siemens product note — so the BOM line is treated as a configured position with a defined order code, not a shelf pick.
Brake, encoder, and the connector that decides the wiring job
Holding brake is included on the shaft, the feedback is a 17-bit hybrid encoder with absolute singleturn resolution, and the power/signal interface is a hybrid AS17 connector — meaning one locking plug carries both phases and the encoder comms back to the SINAMICS S200 drive, which keeps cabinet wiring to a single cable run per axis. Protection class is IP65 with oil seal, so the motor body tolerates plant air that carries cutting fluid mist or light washdown; the plain shaft with tolerance N takes a standard coupling or pinion without a special keyed variant.
Where it sits in the Siemens ordering tree
Lifecycle status is current per the Siemens product record, RoHS compliance is on file since 01-01-18, and REACH Art. 33 candidate-list disclosure is provided as the standard Siemens Reach Information document — the compliance pack a quality inspector will ask for is available against this order code. Export classification carries AL:N / ECCN:N, which removes the export-licence paperwork step for most cross-border shipments and is worth flagging up front to anyone filling the customs line.
