Servo definition and SINAMICS S200 pairing
The 1FL2304-2AF01-1SB0 is a SIMOTICS S-1FL2 low-inertia servomotor in the 1FL2 family, sized as a 45 mm shaft-height unit (SH45) and matched to the SINAMICS S200 drive system.
Mechanical build, encoder, and brake options
The motor is delivered with an angular connector and the AS21bit absolute encoder option, with shaft key and tolerance N — the keyed shaft fixes axial position but introduces a small imbalance set that the downstream drive must accept in its autotune window. The build carries no holding brake, so any vertical-axis application needs an external holding brake sized separately to the load; protection class is IP65 with oil seal, meaning the shaft seal excludes splash and light oil mist but is not rated for sustained immersion or high-pressure washdown.
Compliance declarations on record
The motor has been RoHS-compliant since 01-01-18 and the supplier carries a REACH Article 33 duty-to-inform obligation against the current candidate list — both declarations are required paperwork for any EU-bound shipment or audit trail. The motor is listed as lifecycle status current, and the commercial class is C — produced to order with no return credit — so procurement needs to confirm shaft-height, encoder option, and brake configuration against the BOM before release, not after receipt.
