100 W, 400 V 3AC — small-frame SINAMICS S200 companion
The Siemens 1FL2102-4AF11-1SC0 is a SIMOTICS S-1FL2 servomotor sized as the smallest end of the SINAMICS S200 low-voltage servo line, rated 100 W on a 400 V 3AC supply at 3000 rpm nominal with 0.32 Nm continuous torque — meaning it delivers the same torque at standstill (M0 = 0.32 Nm) as at rated speed, which is the profile a positioning axis needs for short-cycle indexing rather than continuous-duty conveyor work. It carries a hybrid connector and a 21-bit encoder feedback on a 20 mm shaft height frame, and is explicitly listed as the matching motor for the SINAMICS S200 drive — so the cable set, electronic rating plate and one-button tuning are designed to work together as a closed system rather than a generic third-party pairing.
Holding brake, IP65 oil seal, shaft key — what the build options resolve
The order code carries a holding brake, a keyed shaft with Tolerance N fit, and IP65 protection with an oil seal — meaning the motor holds position when the drive is de-energised (the brake is sized for the same 0.32 Nm torque, not for emergency-stop duty), and the seal keeps cutting fluid out of the bearing housing on a wet machine-tool or feeder axis. Packaging dimensions of 315 mm × 182 mm × 172 mm indicate the single-piece carton Siemens ships this low-voltage servo in — small enough to bench-stage without a pallet, which matters when a service swap is being staged next to a control cabinet.
Production class and sourcing posture
Siemens lists 1FL2102-4AF11-1SC0 in lifecycle stage current, with product class C — made to order, non-returnable, non-reusable — so the unit is not pulled from a finished-goods shelf but produced against the order, which sets the realistic expectation that lead time is build-time, not stock-time. Compliance is on the modern European regime: RoHS conformity since 01-01-18 and REACH Article 33 information supplied per the current candidate list, with no export-control flags (AL:N / ECCN:N) — meaning standard commercial export paperwork applies and no dual-use licence gates the shipment.
