What this motor actually is
The 1FL2104-2AF10-1HC0 is a SIMOTICS S-1FL2 low-inertia servomotor in the 1FL2 family sized as the matching drive for the SINAMICS S200 servo drive — three-phase 400 V supply, rated 0.75 kW continuous at 3000 rpm, with a 2.4 Nm rated torque and a 2.4 Nm stall figure (so the rated torque equals the stall torque at this frame, telling you the motor runs out of torque headroom before it runs out of thermal headroom on this axis). The 40 mm shaft height, holding brake, keyed shaft with tolerance N, and the 17-bit absolute encoder fed through a hybrid connector are all on the datasheet description line — that combination fixes the motor's role as a panel-mount rotary axis for short-stroke, high-cycle positioning, not as a flange-through spindle duty.
Electrical and mechanical envelope
The 0.75 kW rating puts this 1FL2 unit at the bottom of the 1FL2 power ladder — it is the framing choice for a small indexing axis, a packaging conveyor registration, or a lightweight pick-and-place Z-θ rather than a heavy feed-roll. Mechanical side: 3000 rpm rated speed, shaft height 40 mm, and a holding brake built in so the axis holds position on de-energisation without an external clamp. Protection class IP54 is dust-protected and splash-proof — fine for a cabinet-internal axis with a sealed cable entry, but it is not the IP65 / IP67 washdown rating, so the motor should not sit where a hose reaches it. Encoder is a 17-bit absolute over the hybrid connector — single-cable hybrid is what keeps the wire run back to the SINAMICS S200 simple: power, brake, and encoder feedback ride one cable rather than three, which matters when you are pulling through a cable track and counting bend cycles.
Family, codes, and how to read the part number
Group Code R220 and Product Group X0DK are the internal Siemens classification labels for this motor — they are what Siemens back-office systems key on for the order and for surcharge calculations, not a separate functional spec the buyer has to engineer against. Knowing them cuts the round-trip on a quote because the rep sees the same codes you do. The part string itself decodes cleanly inside the 1FL2 family: 1FL2104 puts it in the 40 mm shaft-height row, -2AF10 specifies the windings and electrical variant, -1HC0 is the option string (holding brake, keyed shaft, tolerance N, hybrid connector). That's the same option block most 1FL2 buyers are used to reading off the nameplate.
Lifecycle, compliance, and what shipping looks like
Lifecycle stage is recorded as current and product status is Active — the motor is in normal production, not on a last-time-buy window, so a BOM position set against this code can be carried into the next panel run without a forced re-spec. Compliance on file: RoHS-conformant since 01-01-18, with REACH Article 33 candidate-list information supplied through the manufacturer's Reach Information page, and Export Control Regulations listed as AL:N / ECCN:N — no special export licence triggers for the standard cross-border shipment. Product Class is C (made-to-order, non-returnable), so the order is built against the BOM and is not cancelled-and-credited once scheduled. Shipping footprint is a single-piece carton at 382 × 222 × 240 mm — worth knowing because the motor ships as one item and the box goes on a pallet row rather than into a small-parts bin, so receiving docks plan for the carton size.
