What 1FL2103-2AF00-1SC0 is and where it sits
The 1FL2103-2AF00-1SC0 is a SIMOTICS S-1FL2 low-inertia servomotor from the 1FL2 family, sold specifically as the matched servo for the SINAMICS S200 drive line — the motor and drive are paired at order, not mixed-and-matched at panel build. On the nameplate it runs off a 400 V 3AC supply, delivers a rated power of 0.2 kW at a rated speed of 3000 rpm, and holds a continuous rated torque of 0.64 Nm (with a stall torque M0 also at 0.64 Nm, so no pull-up is being claimed on this frame), all on a shaft height of 30 mm — the small frame in the family.
What the mechanical and connector build implies
The shaft carries a shaft key with tolerance N and is built without an oil seal — that's an indoor, clean-side mounting, not a gearbox-end or wet-process spindle. Protection class IP54 covers dust and splashing water but not washdown; the hybrid connector AS21bit carries power and the absolute 21-bit encoder feedback in one shell, so the cabinet-side cable harness lands on a single motor plug rather than separate power and signal leads. This build is supplied without a holding brake — if the axis needs a fail-safe stop under gravity or loss of drive enable, the brake option must be specified on a different variant in the 1FL2 family; do not assume an add-on brake kit retrofits to this order code.
Compliance and substance-restriction posture
Siemens marks the 1FL2103-2AF00-1SC0 as compliant with the RoHS substance restrictions since 01-01-18 and carries the standard REACH Art. 33 duty-to-inform notice on the current candidate list — for a validation pack, this gives you a dated RoHS claim and a defined REACH channel rather than a vendor letter you have to chase down. The product class is coded C — built to order, non-returnable for credit — so a cancellation or quantity adjustment after the order is cut cannot be reversed as a stock return; size the line on the first PO and treat the unit as a make-to-order line item.
Lifecycle and sourcing posture
Packaging is one piece per pack at 315 × 182 × 172 mm, and the unit ships as a single-piece line item — the typical BOM motion is one motor per axis, sourced quoted-to-order against the SINAMICS S200 system order so the drive and motor remain a matched pair on the same commissioning sheet.
