Servomotor ratings and S200 pairing
The 1FL2102-2AF11-1SC0 is a Siemens SIMOTICS S-1FL2 low-inertia servomotor in the 1FL2 family built to run on the SINAMICS S200 drive line — supply voltage 400 V 3AC, rated power 50 W, rated speed 3000 rpm, with continuous and stall torque both at 0.16 Nm. Shaft height 20 mm places this at the small-frame end of the 1FL2 range, intended for compact point-to-point motion in light-load assembly, indexing tables and small feed axes rather than main spindle duty. At 50 W it is sized for bench-top automation, conveyor diverters, labelling heads and small pick-and-place axes where the 0.16 Nm continuous torque and 3000 rpm rating govern the mechanical envelope, not bulk material handling. Holding brake is included, so the rotor stays locked when the drive is de-energised — important on vertical or gravity-loaded axes where the load must not drift on a stop.
Mechanical build and feedback
Encoder is the absolute single-turn 21-bit AS-i feedback variant — the 21-bit resolution sets the position-loop accuracy ceiling and is what the SINAMICS S200 drive expects when auto-commissioning this motor family. A keyed shaft with N tolerance is supplied, so any coupling or pulley mounted on the shaft end must use a keyway-compatible mating element. Protection class IP65 with oil seal on the shaft pass-through — the oil seal keeps light cutting fluid and lubricant mist from creeping past the bearing into the encoder housing, which matters on small CNC tooling or anywhere a gearhead sits inboard of the motor. The hybrid connector carries power and signal in one moulded body, simplifying cabinet routing on the drive side.
Ordering and compliance identifiers
Order code 1FL2102-2AF11-1SC0 ships under Group Code R220 and Product Group X0DJ. The line is classified as Product class C — products manufactured or produced to order that cannot be reused or re-issued as stock credit. Packaging quantity is 1 piece per shipper, packed dimensions 315.00 x 182.00 x 172.00 mm. Expect a factory-build lead profile rather than off-the-shelf shelf stock on this code. Compliance: RoHS conformity has been in force since 01-01-18, REACH Art. 33 candidate-list information is published, and the part is not export-controlled (AL:N / ECCN:N).
