For the sizing decision: 0.75 kW continuous output at 3000 rpm lands this motor in the small-format positioning servo range — typical duty covers light conveyor indexers, small-format pick-and-place axes, and auxiliary feeds where a 400 V three-phase bus is already in the panel and the SINAMICS S200 is the chosen drive. ## Mechanical stack: connector, brake, seal The motor ships with the angular connector variant for power and feedback, an integrated holding brake for vertical-axis and held-load retention, a keyed shaft with N tolerance, and an oil-sealed IP65 housing — so the unit is sealed for factory-floor splash and dust but not for washdown duty. IP65 with oil seal at this frame means the sealing approach is the cable-connector face plus shaft seal, not a fully potted stator; mating cable assemblies must use the correct Siemens-spec angular connector to preserve the rating through the cable entry. ## Lifecycle, class, and compliance trail Lifecycle is recorded as active in both the product-status field and the lifecycle stage — this is a current-production part on Siemens's books, not a phase-out or last-time-buy position. The product class is C — built to order with no return-for-credit path — so orders are placed against a configured BOM and shipped as manufactured; stocking expectations should be planned around the production-build window, not off-the-shelf shelf-pull. ## What it is not, and how to specify it The 24-bit angular connector feedback variant is the high-resolution absolute encoder option for closed-loop positioning; lower-resolution variants in the same 1FL2 family exist, so the -1SB0 suffix is the deciding string on the encoder choice, not just the brake and seal options.","metaTitle":"Siemens 1FL2304-4AF11-1SB0 Servo Motor, 0.75 kW, 400V","metaDescription":"Siemens 1FL2304-4AF11-1SB0 SIMOTICS S-1FL2 servo motor, 400V 3AC, Pn=0.75 kW, Nn=3000 rpm, IP65 with holding brake.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors"],"specifications":{"title":"1FL2304-4AF11-1SB0","Group Code":"R220","description":"SIMOTICS S-1FL2 Supply voltage 400V 3AC Pn=0.75kW;Nn=3000rpm M0=3.02Nm;Mn=2.39Nm Shaft height 45mm With angular connector AS21bit With shaft key, Tolerance N With holding brake Protection class IP65 with oil seal Matching drive SINAMICS S200","Product Group":"X0DM","Product class":"C: products manufactured / produced to order, which cannot be reused or re-utilized or be returned against credit.","Quantity Unit":"1 Piece","Product Family":"1FL2 servomotors for SINAMICS S200","lifecycle_stage":"current","Packaging Quantity":"1","Export Control Regulations":"AL : N / ECCN : N","Packaging dimensions (L x W x H)":"432.00 x 222.00 x 240.00 mm","Compliance with the substance restrictions according to RoHS directive":"Since: 01-01-18","REACH Art. 33 Duty to inform according to the current list of candidates":"Reach Information"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/86470a10569b6c31c0cdb568879838fa.pdf","sourceUrl":"https://sieportal.siemens.com/en-ae/products-services/detail/1FL2304-4AF11-1SB0?tree=CatalogTree"},"ai":{"faq":[{"question":"What compliance documentation comes with 1FL2304-4AF11-1SB0?","answer":"Siemens records RoHS conformity since 01-01-18, a REACH Article 33 duty-to-inform disclosure is available, and the export-control markings are AL:N and ECCN:N — no export licence required for standard commercial destinations."},{"question":"What drive pairs with the 1FL2304-4AF11-1SB0?","answer":"The motor is part of the 1FL2 family explicitly matched to the SINAMICS S200 drive platform, and the 400 V 3AC winding means the drive must be the 400 V class variant on the S200 line."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/1FL2304-4AF11-1SB0","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/1FL2304-4AF11-1SB0 when reusing this data.
