Form-factor and what ships in the box
The Siemens 1FL2103-4AF00-1SC0 is a SIMOTICS S-1FL2 low-inertia servomotor sized into the 30 mm shaft-height frame, configured for direct mating with a SINAMICS S200 drive via a hybrid connector — the cable side therefore carries both power and encoder signals in one assembly, eliminating the two-cable layout older 1FL1 retrofit sites still run. Packaging footprint for a single piece is 315.00 x 182.00 x 172.00 mm, and the part is shipped as one unit per quantity — the small-frame servo typically arrives on the receiving dock in the OEM carton with its anti-vibration foam rather than bulk-packed.
The motor's continuous rating is Pn = 0.4 kW at Nn = 3000 rpm with a stall and nominal torque of M0 = 1.27 Nm / Mn = 1.27 Nm — a flat torque-versus-speed profile through rated speed, which is what makes the 1FL2 frame a fit for constant-torque loads like small part feeders, indexing tables, and packaging conveyors rather than constant-power spindles. Supply voltage is 400 V 3AC, drawn through the hybrid connector listed on the motor build; the encoder is the 21-bit AS resolution variant, absolute single-turn, which means the drive retains position on power-cycle without a homing routine provided the multi-turn battery or drive-side buffering is in scope. Holding brake is omitted on this configuration and sealing is IP54 without an oil seal — so the motor is intended for indoor cabinet or machine-internal mounting, not washdown or outdoor enclosures, where an IP65 or higher rating would be specified in the part number suffix.
Compliance file the receiving desk should expect
RoHS compliance is declared since 01-01-18, putting this build inside the post-2018 substance-restriction envelope; REACH Article 33 disclosure applies per the current candidate list, and the documentation is normally furnished with the Siemens declaration of conformity on request. Export control classification shows AL:N / ECCN:N, so the part does not require an export license for typical commercial shipments; the Group Code R220 and Product Group X0DJ are Siemens-internal classification slots used for catalog routing rather than any regulatory code.
Procurement posture for an active-build servo
Siemens marks the part Active in the lifecycle record, and the product class is built-to-order — orders quote against the BOM and lead time is confirmed at RFQ through independent distribution, with current pricing and availability reconfirmed at the same point. Because the part is built to order with no return-for-credit path, the right move for a multi-axis machine build is to consolidate the 1FL2 line-up onto one preferred-supplier catalog line and one PO — collapsing tail-spend and avoiding a per-unit requisition that costs more to process than the motor itself.
