What 1FL2104-4AG10-0MC0 delivers on the axis
The Siemens 1FL2104-4AG10-0MC0 is a SIMOTICS S-1FL2 low-inertia servomotor from the 1FL2 family that pairs with the SINAMICS S200 drive, sized for 1 kW continuous power at 3000 rpm with a 3.2 Nm rated torque — the same figure is published for stall torque M0, so the motor holds its rated point without a torque step-down at zero speed. The 200 V three-phase supply and shaft height 40 mm frame place it in the compact S200 system envelope; the AM21 bit hybrid connector and IP54 protection class without an oil seal set it up for a clean cabinet-side feed with a sealed cable gland at the motor gland plate, not a wet-duty bulkhead.
Frame, brake, and connector details buyers should confirm
Ordering specifics are part of the code itself: plain shaft with tolerance N, integrated holding brake for vertical-axis and gravity-loaded lockout, and the AM21 bit single-cable hybrid connector — one cable carries power and the 21-bit absolute encoder feedback, which simplifies cabinet entry compared to a separate resolver feedback run.
Compliance and export posture for cross-border sourcing
Siemens ships the 1FL2104-4AG10-0MC0 with RoHS compliance stated since 01-01-18 and a REACH Article 33 information obligation that points to the current candidate list — both standard for EU-bound panel builds and for any importer who has to pass the substance-restriction check at goods-in. Export control is listed as AL: N / ECCN: N, so no export licence stamp is required for routine cross-border movement under standard EAR99-style routing — useful when the part is being pulled from a non-domestic independent distributor into a North American or APAC build.
Lifecycle and stocking reality
The product family is built-to-order under product class C — units are produced per order specification and are not returnable for credit, so a stockout is not solved with a standard RMA; the build slots into a production schedule rather than a shelf replenishment cycle. Lifecycle is recorded as active, with the ordering code still part of the published catalog — quoting is run against the RFQ with availability and lead time confirmed at quote time, which is the only honest read of supply for a built-to-order Siemens servo line.
