What the nameplate says — and what the spec table confirms
The Siemens 1FL2104-4BG01-1MC0 is a SIMOTICS S-1FL2 low-voltage servo motor built for the SINAMICS S200 drive family, with Pn 1 kW, Nn 3000 rpm, M0 3.2 Nm and Mn 3.2 Nm at a 200 V 3AC supply rail. Shaft height 40 mm, hybrid connector AM21bit with 21-bit resolution, shaft key with tolerance N, no holding brake — so the motor delivers rated torque continuously with no static parking torque when de-energised, which is the configuration for non-vertical axes where the drive brake is acceptable. The unit is rated to IP65 with oil-seal at the shaft entry, which means the housing tolerates dust ingress and low-pressure water jets plus oil mist typical of a machine-tool or general automation cell — washdown is not implied, but the sealing is sufficient for gearbox-adjacent and lightly oily environments.
Drive pairing and mechanical fit
Group Code R220 and Product Group X0DK locate the part inside Siemens' ordering and pricing structure for cataloguing and replenishment; these are not functional ratings but they are what appear on the order acknowledgement and the packing slip, so they are the cross-check fields for a quality-doc control sign-off.
Compliance documentation for the supplier-quality file
RoHS compliance is documented since 01-01-18, so the declaration of conformity is back to the 2018 substance-restriction regime and the part is accepted into any RoHS-controlled build that requires the 2011/65/EU + (EU)2015/863 scope. REACH Art. 33 duty-to-inform applies via the candidate-list reference; this is the field that matters for European importers — any substance above the 0.1 % w/w threshold on the current candidate list would trigger a notification, and the supplier is expected to surface that proactively through Reach Information. Export Control Regulations read AL: N / ECCN: N, which means no export licence is required for typical industrial destinations — the part can ship under standard commercial export paperwork rather than an ECCN-filed shipment.
Production status and orderability
Lifecycle stage is listed as current and the product status is Active, so the 1FL2104-4BG01-1MC0 is in normal Siemens production and not on a phase-out trajectory. The product class is 'C' — built to order, non-returnable for credit — which is the Siemens convention for configured servo motors that are wound and assembled against the order code rather than pulled from generic shelf stock. Because the part is built to order, single-piece orders ship in the quantity unit shown (1 Piece) and the packaging dimensions 315.00 x 182.00 x 172.00 mm reflect the configured motor, not a generic blank. No second source or pin-compatible alternate is listed in the family description — the 1FL2 line is the sole Siemens platform for this shaft-height / rating slot, so an equivalent from outside the family would be a different frame and connector rather than a true drop-in.
