Headline ratings — 0.4 kW, 3000 rpm, 1.27 Nm at the shaft
The 1FL2103-4AG11-1MC0 is a SIMOTICS S-1FL2 low-inertia servo in the 1FL2 family, designed to pair with a SINAMICS S200 drive on a 200 V 3AC bus, rated 0.4 kW (Pn) at a nominal speed of 3000 rpm with both M0 and Mn at 1.27 Nm. That continuous-torque figure equal to standstill torque is typical of a low-inertia design — it keeps the motor inside its continuous envelope during low-speed indexing moves, so the drive does not have to back off the torque limit on every dwell in the cycle.
Mechanical envelope and connection side
Built on a 30 mm shaft height frame, the unit ships with a keyed shaft (tolerance N), an integrated holding brake, and a 21-bit hybrid connector — meaning the power and feedback conductors land through one plug rather than separate motor-power and encoder receptacles. IP65 protection class with an oil seal on the shaft end closes the unit against coolant mist and low-pressure washdown, which is the deployment ceiling expected at the machine, not the plant-floor level: the motor is sealed against splash and oil, not against full immersion or high-pressure hot washdown.
Compliance and product-class paperwork
The motor is declared RoHS-compliant since 01-01-18, REACH Art. 33 information is available through the standard Siemens duty-to-inform channel, and the export classification is AL:N / ECCN:N — no special licence is required to ship the unit cross-border. Under the Siemens product-class taxonomy this order code sits in class C — built to order, non-returnable, non-reusable — so a cancelled line cannot be returned for credit; size the order to the panel build rather than to a trial quantity.
