Mechanical envelope and shaft fit
Siemens 1FL2102-2AF01-1SC0 is a SIMOTICS S-1FL2 low-inertia servo in the 1FL2 family, sized for a SINAMICS S200 drive on 400 V 3AC with a rated power of 50 W at 3000 rpm and standstill torque of 0.16 Nm. The shaft height is 20 mm with a keyed shaft in N tolerance and no holding brake, so the unit is the unbraked variant in the family — pairing a brake-equipped servo into this BOM line would require a different order code.
Feedback, sealing, and what guards against contamination
Feedback is the 21-bit absolute single-turn encoder carried through the AS-interface hybrid connector, which bundles power and signal in one plug — a clean wiring-side win but a non-negotiable connector spec on the drive end. Protection class IP65 with oil seal on the shaft: the seal lets the motor sit close to the workpiece on a tool-change axis or a wetter bench without coolant pull-by at the shaft exit, and the IP rating applies only when the mating connector is correctly seated.
Compliance scope for the build file
REACH Article 33 duty-to-inform applies; the Reach Information note on file means the seller passes through any candidate-list substance disclosure when the part is quoted, rather than burying it in a generic compliance footer. Export control is AL:N / ECCN:N — the part is not licence-controlled for cross-border shipment, which keeps parallel-import and repair-exchange logistics straightforward.
Production class and how to order
Product class C is flagged as made-to-order, non-returnable — the BOM line cannot be cancelled back into stock and re-credited, so the panel builder commits the quantity at order entry rather than over-spec-ing.
