The 0.4 kW slot in the SIMOTICS S-1FL2 line
The Siemens 1FL2103-4AF11-0HC0 sits in the SIMOTICS S-1FL2 low-voltage servomotor family, sized as a 400 V 3AC, 0.4 kW unit with a rated speed of 3000 rpm and a continuous stall/rated torque of 1.27 Nm. It carries a 30 mm shaft height, plain shaft with tolerance N, an oil-seal-protected IP65 housing, and a holding brake — the configuration a system integrator picks when a small, sealed axis has to hold position on power loss. The encoder side is the AS17-bit absolute single-turn variant wired through a hybrid connector, which keeps the power-and-feedback cable to a single assembly rather than two separate glands. Matched drive is listed as the SINAMICS S200 — that's the amplifier the motor is qualified with, not a recommendation list.
Headline ratings and what they decide
Supply 400 V 3AC with Pn = 0.4 kW and Nn = 3000 rpm frames this as a low-inertia, continuous-duty axis rather than a high-speed spindle motor — M0/Mn = 1.27 Nm means no torque overshoot at zero speed, which matters for indexing tables and pick-and-place heads that spend most of the cycle near a hold. IP65 with oil seal is the housing rating in the catalog description; the seal means the shaft lip is sealed against low-pressure coolant and light washdown, but it does not extend the rating to submerged or high-pressure cleaning. For controls integrators building a SINAMICS S200 drive panel, that defines the cabinet-side vs. machine-side boundary: the motor can sit outside a fully sealed enclosure; the drive still belongs inside. Holding brake is included on this part number (-0HC0 option string). The bake is non-optional inside this catalog code, so a buyer who doesn't need a brake must pick a different variant in the same family.
Document the procurement packet expects
Product class is C — built to order per the configured option string, with no return-for-credit clause — so this is a configured, non-cancellable line once the order is opened. Packaging is one piece per shipper, with outer carton dimensions 315.00 x 182.00 x 172.00 mm for the single-piece pack. Compliance: RoHS conformity since 01-01-18, REACH Art. 33 duty-to-inform carried by the manufacturer, and export-control class AL:N / ECCN:N — no special export license triggers for standard destinations. For a configured-to-order (class C) product that's the expected state — the line stays open as long as the matched SINAMICS S200 drive platform does.
Sourcing posture for this order code
Independent distribution handles configured class-C servomotors one RFQ at a time: the option string has to be re-validated against the current Siemens configurator before a clean shipper is committed. Quote requests should carry the full -0HC0 option suffix plus the target quantity so the supply chain doesn't have to guess on variant. No stock count, lead-time window, or price list applies on a page like this; those answers are confirmed only when an RFQ is opened, since the matched SINAMICS S200 drive, the hybrid connector cable set, and the holding-brake option each come from separate order codes that the buyer usually bundles together.
