What this motor is on the line
The 1FL2103-4AF11-0MC0 is a SIMOTICS S-1FL2 low-inertia servomotor from the 1FL2 family, dimensioned for the SINAMICS S200 drive platform and built around a 30 mm shaft height — that frame is the 0.4 kW position in the line, sized for compact moving axes (small gantries, indexing tables, feeders) where the 1.27 Nm continuous torque at 3000 rpm covers light dynamic loads without oversizing the drive. Group Code R220 and Product Group X0DJ identify the commercial line on Siemens order paperwork; the listing's product class is C — built to order, non-returnable — so any RFQ must carry a firm quantity and configuration.
Headline ratings and what they let you wire
Supply is 400 V 3AC, with Pn = 0.4 kW, Nn = 3000 rpm, and M0 = Mn = 1.27 Nm — the stall and continuous torque being equal means the motor can hold rated load at zero speed without time-derating, which matters for vertical or clamp axes where the holding brake alone isn't carrying the static load. Feedback is the AM21bit encoder, wired through the hybrid connector — single-cable hybrid power+feedback eliminates the separate encoder tail and cuts cabinet gland count; the 21-bit resolution gives the S200 the absolute position feedback it needs for commissioning and safety-related stop functions without an external homing routine. The plain shaft with tolerance N, holding brake, and IP65 with oil seal spec mark this as the cabinet-side-and-machine-side variant — the oil seal keeps light cutting fluid and coolant mist off the front bearing, and the holding brake is the parking brake for de-energised axes, not a safety-rated stop.
Where it sits in the SINAMICS S200 system
Pairing is locked to the SINAMICS S200 drive family — the motor and drive are matched at order level for electrical and mechanical parameters, so a 1FL2103-4AF11-0MC0 dropped onto an older SINAMICS V90 or S120 system is not a plug-and-play replacement and would need re-commissioning. Export-control markings read AL:N / ECCN:N, meaning no special export licence applies to most destinations; packaging is one-piece at 315 x 182 x 172 mm, which is the bench-receiving footprint for incoming inspection rather than a selection parameter.
Lifecycle and what the buyer can commit to
Lifecycle is current (Active) per the official status record, so the 1FL2103-4AF11-0MC0 stays on the BOM without an LTB clock — but because product class is C (built to order, non-returnable), every RFQ should lock the configuration and quantity against the S200 drive pairing before release.
