What 1FL2104-2AG11-0HC0 is
The 1FL2104-2AG11-0HC0 is a Siemens SIMOTICS S-1FL2 low-inertia servomotor in shaft height 40 mm, wound for a 200 V 3AC supply and rated 0.75 kW with a rated speed of 3000 rpm and a standstill/continuous torque of 2.4 Nm — which means the same motor covers both the constant-torque lower speed range and the rated point on a SINAMICS S200 drive without a gearbox stage. It ships with a 17-bit single-turn absolute encoder (AS-i interface via the hybrid connector) and a holding brake, in an IP65 body with an oil seal, so the feedback and brake cabling enter through a single pre-wired hybrid connector rather than separate plug sets.
Ratings that decide the fit
0.75 kW at 3000 rpm with 2.4 Nm continuous torque puts this unit squarely in the small-format machine-building band — packaging machines, small feeders, label applicators, indexing tables — where the 3000 rpm ceiling is the speed ceiling, not a derated operating point. IP65 with oil seal is the version to specify where gearbox lubricant or cutting fluid can reach the shaft; the shaft itself is plain (no key) to tolerance N, which keeps coupling alignment tolerant but rules it out for applications that need a keyed positive drive without a separate clamp. The holding brake is integrated at the factory, so a vertical axis using this motor does not need a third-party brake selection — the brake coil is wired through the same hybrid connector and the S200 drive handles the brake timing on enable/disable.
Compliance paperwork covers RoHS since 01-01-18 and REACH Art. 33 information duty; no AL or ECCN export classification (AL:N / ECCN:N), so it ships without an export-licence gate to most destinations. For retrofit work, the 40 mm shaft height, 200 V 3AC winding and the S200 drive pairing are the constraints that actually decide whether an old axis can be modernised in place — meeting it where it is means the existing mounting footprint, coupling and cable duct stay usable, and the S200 drive replaces the older controller without rewiring the cabinet.
