Define the 100 W S-1FL2 axis
Siemens 1FL2102-4AF11-0HC0 is a SIMOTICS S-1FL2 low-inertia servomotor in the 20 mm shaft-height frame, designed as a matched motor for the SINAMICS S200 drive system. It carries a 400 V 3AC supply, 100 W rated power (Pn), 3000 rpm rated speed (Nn), and equal 0.32 Nm for both stall torque (M0) and rated torque (Mn) — a profile that suits small-format positioning axes and light-feed auxiliary drives rather than the main spindle. The motor ships with a plain shaft (tolerance N), an integrated holding brake, and a 17-bit absolute encoder wired through the AS-style hybrid connector, so the connector/cable set is part of the commissioning picture, not an accessory chosen later. Protection class IP65 with an oil seal means the body tolerates plant-side coolant splash and oil mist; it is not a washdown-rated food-grade enclosure.
Sizing decisions the ratings drive
At 100 W Pn and 0.32 Nm rated, this 1FL2102 frame is the entry of the S-1FL2 line — the right fit for conveyors, small indexing tables, label-and-cut stations, and feeder axes where the demand torque stays well below 1 Nm and the cycle rate is modest. The fact that M0 equals Mn means the motor's continuous and short-term thermal envelopes are nearly identical, so the integrator does not need a large overload margin to handle acceleration peaks. Because the mating drive is the SINAMICS S200 and the encoder is read out through the AS hybrid connector, the cable/connector pair must be specified together — the hybrid connector is not a generic M12 or M23. The holding brake is integrated at the factory; there is no field retrofit path, so if a customer's axis ever needs a brake on the spare unit but not on the original, that has to be set at the order-code stage.
Kit completeness and order-class reality
Siemens classifies this motor under product class C — products manufactured to order that cannot be reused or returned against credit. For the kitting lead, that means the line item is built when the order lands: there is no returns safety net if a unit is over-ordered or mis-specified, and the BOM line should be frozen with the holding-brake option and connector style confirmed before the RFQ goes out. Pricing and availability are confirmed against the BOM at quote time through independent distribution; no public price, stock count, or lead-time number is asserted here.
Internal classification stamps
On Siemens' own catalogue row, the motor carries Group Code R220 and Product Group X0DJ — the classification stamps used internally for warehousing, MRO storeroom lookups, and cross-line engineering queries. These are not selection parameters; they are the codes the storeroom or the line engineer types into the SAP/IRIS lookup to land on this exact part number. Packaging is one piece per carton at 315 x 182 x 172 mm — the footprint the inbound dock needs to plan for when the spare unit arrives, not a design parameter.
