Active servo motor, S-1FL2 family
The Siemens 1FL2103-4AG11-0SC0 is a SIMOTICS S-1FL2 low-inertia servomotor in the 1FL2 product family for the SINAMICS S200 drive system, sized at 0.4 kW rated power, 3000 rpm rated speed, and 1.27 Nm standstill and rated torque, with a shaft height of 30 mm — a compact frame that slots in directly with the SINAMICS S200 drive electronics for panel or machine-builder integration. The product is listed in lifecycle as current, and the part carries no end-of-life notice on the record — a healthy BOM line for an integrator specifying against the SINAMICS S200 architecture today.
Ratings and what they decide on the line
The 1.27 Nm standstill figure at 3000 rpm rated speed (0.4 kW) means this frame is engineered for fast-acceleration, low-inertia loads — small parts feeders, conveyor indexing, lab automation, and similar applications where torque density per frame size matters more than continuous torque. Supply voltage is 200 V 3AC, with a 21-bit hybrid connector as the feedback interface, plain shaft (tolerance N), a holding brake for vertical-axis or zero-position retention, and IP65 protection with oil seal — the sealing package supports cabinet-edge or machine-frame mounting where coolant mist and oil splash are present, but the motor body itself is the wet-end barrier and the sealing washer at the flange must be seated correctly to keep that rating valid.
Compliance and documentation trail
The motor is RoHS-compliant per the substance restrictions directive since 01-01-18, and the listing carries the REACH Article 33 duty-to-inform note — the relevant candidate-list substance disclosures are available through the standard Siemens Reach Information channel for this order code. Logistics metadata is clean for cross-border movement: export classification AL:N / ECCN:N, packaged one piece per carton at 315.00 x 182.00 x 172.00 mm, and Group Code R220 / Product Group X0DJ — useful when the part shows up on a customs document, packing list, or Siemens order acknowledgement and you need to reconcile it against the PO line.
Sourcing posture
Active stock posture on the manufacturer's side, but the product class is flagged as made-to-order with no return-for-credit pathway — independent distribution typically quotes against the BOM quantity, and lead time and price-break ladder are confirmed at RFQ rather than pulled off a price sheet. Pairing matters: this motor is matched to the SINAMICS S200 drive platform per the description line, so an RFQ should reference both the motor order code and the drive variant to keep the BOM internally consistent — quoting just the motor leaves the commissioning engineer without the drive-side cross-reference.
