What the order code covers
The Siemens 1FL2204-4AF11-1HC0 is a SIMOTICS S-1FL2 low-inertia servo motor rated 400 V 3AC at Pn=1 kW with a rated speed of 3000 rpm; stall torque M0 and rated torque Mn both sit at 3.2 Nm, so the motor has no torque fold-off between standstill and rated speed and delivers full pull-out through the working envelope. Mechanical fit is fixed by the 40 mm shaft height, a keyed shaft with Tolerance N, and a hybrid connector on the cable end — meaning the matching cable assembly is not the standard M17 round type found on the older 1FK/1FT lines, but the S-1FL2 hybrid signal/power plug.
Sealing, contamination, and cabinet placement
Protection class IP65 with oil seal means the body and shaft seal hold up against coolant mist and light oil exposure typical of a machine-tool or pick-and-place cell — the seal is on the shaft, not just the housing face, so vertical or inverted mounting with a gearbox above is acceptable without extra slinger hardware. For washdown or food-grade lines, IP65 is the floor, not the ceiling: confirm the mating connector spec before specifying. The unit ships in a 382 x 222 x 240 mm package as a single-piece order; Group Code R220 / Product Group X0DK on the Siemens ordering system is how the line item is matched against the factory's SAP record when verifying incoming goods.
Lifecycle status and order class
Manufacturer lifecycle stage reads current, so the part is still being produced by Siemens under the 1FL2 family. Commercial class is C — built-to-order, non-returnable, non-reusable against credit — meaning the right move on a spare is to order against the specific cabinet BOM position, not against a generic 'servo motor' line; a wrong shaft height or missing brake variant cannot be credited back.
