200 V 3AC servo sized for the SINAMICS S200 line
The 1FL2104-4AG11-1MC0: The part is a SIMOTICS S-1FL2 low-inertia servo with a 1 kW rated power (Pn=1kW), 3000 rpm nominal speed (Nn=3000rpm), and matched 3.2 Nm standstill / rated torque (M0=3.2Nm; Mn=3.2Nm), so the drive-and-motor pair is dimensionally balanced rather than oversized for the bus. It carries the 40 mm shaft height of the compact 1FL2 family, addressed to packaging, small-format indexing, and lab/bench automation where the inertia-to-load ratio matters more than peak torque headroom. Output is via an AM21bit hybrid connector and a keyed shaft with N tolerance, with an integrated holding brake to hold position when the bus is de-energised — the brake is the safety-side hold, not a dynamic stop, so any vertical-axis sizing should still budget an external mechanical brake or counterweight for the E-stop case.
IP65 with oil seal and the S200 bus contract
Protection class is IP65 with oil seal, which means the body resists dust and low-pressure water jets typical of a washdown-adjacent cell, but the rating is the sealed-side figure when the hybrid connector is mated — the cable gland and counter-connector carry their own ingress class and the system-level rating is only as good as the mating half. The motor is listed for the SINAMICS S200 drive family; mixing it with an S210, V90, or earlier SINAMICS drive requires re-validating the encoder resolution (AM21bit, single-turn, multi-turn per variant) and the holding-brake wiring because the S200 connector pin map and the brake control logic differ from those older platforms.
Lifecycle, compliance, and how the line ships
Lifecycle stage is current and product status is Active, so the part is in serial production rather than available only through surplus or last-time-buy channels; no official successor has been published for this order code. RoHS substance restrictions have applied since 01-01-18 and REACH Article 33 candidate-list information is supplied on demand, which is the documentation pack a controls integrator typically asks for at the panel build stage. Export control is AL:N / ECCN:N, simplifying cross-border paperwork, and the order class is "C" — built to order with no return-for-credit path — so the BOM commit needs to be locked before the factory starts the build slot. Packaging is a single-piece shipper at 382.00 x 222.00 x 240.00 mm; small-format but rigid enough that the motor should be uncrated and inspected before the holding-brake release voltage is ever applied.
Category strategy: where this 1FL2 sits in the Siemens portfolio
Within the Siemens motion stack, the 1FL2 family is the compact, low-inertia option that pairs with SINAMICS S200 — distinct from the higher-inertia 1FK2 / 1FT2 lines that target heavier-load machine tools. Group Code R220 and Product Group X0DK are the internal classification keys for this servo line; the group code in particular is what a procurement system uses to roll this part up under the motion-control spend under management, separate from frequency inverters and gear motors. Because there is no on-record pin-compatible second source and no published successor order code, de-risking the supply base means qualifying a second Siemens family member or a third-party servo on the same drive platform, not chasing an identical cross-reference.
