What 1FL2103-4AG01-1HC0 is and where it sits
The 1FL2103-4AG01-1HC0 is a SIMOTICS S-1FL2 low-inertia servomotor in shaft height 30 mm, sized for 200 V 3AC drives and built as part of the 1FL2 family matched to the SINAMICS S200 servo drive system — so it drops into the standard S200 cable and commissioning ecosystem without a separate motor parameter file.
Rating deep-dive — 0.4 kW, 1.27 Nm, 3000 rpm
Continuous rated power is 0.4 kW with a rated speed of 3000 rpm, and the standstill torque M0 equals the rated torque Mn at 1.27 Nm — meaning the motor can hold 1.27 Nm at zero speed continuously without falling out of the thermal envelope, which simplifies sizing on vertical or constant-torque axes where the holding torque matters more than the rated speed. The body carries IP65 with an oil seal on the shaft, so the unit is sealed against low-pressure water jets and oil mist at the shaft exit — acceptable for machine-tool and food-adjacent cabinets but not a washdown-rated enclosure; the hybrid connector AS17bit carries power and the 17-bit absolute encoder signals in one plug. This variant is supplied without a holding brake and with a keyed shaft (tolerance N) — confirm the axis needs no brake for an E-stop, because adding a brake later is a different order code, not a field retrofit.
Compliance and ordering context
RoHS compliance has been in force since 01-01-18 and REACH Art. 33 disclosure is supplied via the manufacturer's Reach Information page, which is the standard dossier set for the S200 / 1FL2 platform and covers the EU substance-restriction regime the build will be shipped into. Export control is AL: N / ECCN: N, so the part ships without a U.S. export licence gate — a useful note for cross-border builds where the ECCN line is the first thing customs asks for. Siemens classifies the unit under Group Code R220 and Product Group X0DJ; the product class flag indicates it is produced to order and cannot be returned against credit, so the right way to bring this in is to confirm the BOM quantity up front rather than stock-and-return.
