It carries an AM21 21-bit absolute encoder, a shaft key with N tolerance, and a holding brake — the standard package for a positioning axis that must hold position when the bus drops or the drive stages out of enable. Shaft height 45 mm places it in the lower end of the 1FL2 frame range, so the cabinet-side mounting footprint stays compact while still delivering the torque density the SINAMICS S200 is tuned for at this power point. In deployment terms, this is the motor you'd reach for on a small-format pick-and-place gantry, a feeder or indexing table, or a short-stroke linear actuator fed from a SINAMICS S200 — anywhere the loop bandwidth of the S200 platform needs a low-inertia rotor the 1FL2 family was characterised against. ## IP65 with oil seal — the cabinet-perimeter spec that decides washdown siting Protection class IP65 with oil seal means the shaft pass-through is sealed against light coolant mist and oil film typical of a machine tool or gearbox sump — the seal is the part that lets this 1FL2 sit just outside the wet zone rather than only deep inside a sealed cabinet. For commissioning, the angular connector orientation is fixed at build time, so the cable gland direction needs to be confirmed against the cabinet layout before the motor is mounted — the cable can't be rotated on a re-terminated lead the way it can on a straight connector. ## Built-to-order, single-piece line — what the ordering record says The product class for 1FL2304-4AF11-1MB0 is class C — a build-to-order configuration that is manufactured per the order, cannot be re-used or re-utilised, and is not returnable against credit. Practical effect for the buyer: lead time is governed by Siemens build slot rather than shelf stock, and the configuration must be locked before the PO is released. The current lifecycle record shows the part as active, Group Code R220 in Product Group X0DM — both ordering-channel fields that have to appear on the purchase order line so the order routes to the correct factory slot. Packaging is a single-piece shipper at 432.00 x 222.00 x 240.00 mm — useful for the receiving dock and for sizing the MRO shelf footprint when a line-down spare is being staged. Because 1FL2304-4AF11-1MB0 sits in build-to-order product class C, the practical supply path is to quote against the configured BOM line: pricing and the build slot lead time are confirmed at RFQ submission, with no implied shelf-availability claim. Independent distribution handles the order against the same configuration code, so a buyer doesn't need to convert part numbers when sourcing through a non-OEM channel.","metaTitle":"Siemens 1FL2304-4AF11-1MB0 Servo Motor, 0.75 kW, 400V 3AC","metaDescription":"Siemens 1FL2304-4AF11-1MB0 SIMOTICS S-1FL2 servo, 0.75 kW at 400 V 3AC, 3000 rpm, IP65 with oil seal, holding brake, AM21 encoder.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors"],"specifications":{"title":"1FL2304-4AF11-1MB0","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 AM21bit 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/6417df6431b64ab08006de2beadcb811.pdf","sourceUrl":"https://sieportal.siemens.com/en-ae/products-services/detail/1FL2304-4AF11-1MB0?tree=CatalogTree"},"ai":{"faq":[{"question":"What are the headline ratings of 1FL2304-4AF11-1MB0?","answer":"It is a 400 V 3AC SIMOTICS S-1FL2 servo rated 0.75 kW at 3000 rpm nominal, with 3.02 Nm stall torque (M0) and 2.39 Nm rated torque (Mn), shaft height 45 mm, AM21 21-bit absolute encoder, holding brake, and IP65 protection with oil seal — paired with a SINAMICS S200 drive."},{"question":"What compliance documentation is on record for 1FL2304-4AF11-1MB0?","answer":"The compliance record shows RoHS conformance since 2018-01-01 and an active REACH Art. 33 duty-to-inform obligation; export classification carries AL:N and ECCN:N, so no export-control licence is required to ship cross-border."},{"question":"What is the closest alternative configuration in the 1FL2 family?","answer":"Sourcing the exact 1FL2304-4AF11-1MB0 configuration against an RFQ is the cleanest path; a variant substitution would require a fresh BOM review."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/1FL2304-4AF11-1MB0","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/1FL2304-4AF11-1MB0 when reusing this data.
