It carries an AM21-bit singleturn hybrid encoder, a keyed shaft with N tolerance, and a holding brake, with IP65 sealing plus an oil seal at the shaft exit — the oil seal is what allows the motor to live on a gearbox or near a gear-lube splash zone without wicking lubricant past the bearing shield. Because this motor belongs to the 1FL2 family built explicitly for SINAMICS S200 drives, the safe assumption is S200-only pairing — migrating it onto a S210, V90, or older S120 line means the encoder commutation table and the drive parameter set stop lining up, so the servo loop will not close cleanly without a re-commissioning pass. ## Ordering posture and what the product class C label actually means Siemens lists this order code under product class C — a build-to-order configuration that is not returnable for credit and cannot be re-used or re-utilized once the line is cut — so each unit ships against a fresh BOM line with no surplus float on the shelf. Compliance footprint is straightforward: RoHS conformity since 01-01-2018, REACH Article 33 candidate-list reporting via Siemens' Reach Information page, and export classification AL:N / ECCN:N — no licence key required for typical cross-border industrial shipments. ## Mechanical envelope and what lands on the receiving bench Shaft height 30 mm positions this motor at the small-frame end of the 1FL2 family, which is the size class typically driving small-format index tables, lab automation axes, light-duty packaging conveyors, and electronic-component pick-and-place gantries where the 1.27 Nm continuous torque is enough to move the payload without oversizing the cabinet. The shipping carton is 315 × 182 × 172 mm for a single piece — a compact pack that drops onto a receiving bench without a lift, and the AM21-bit hybrid connector lands on the drive end of the cable without needing a separate terminal box on the motor housing.","metaTitle":"Siemens 1FL2103-4AF11-1MC0 servo motor, 0.4 kW, 3000 rpm","metaDescription":"Siemens 1FL2103-4AF11-1MC0 SIMOTICS S-1FL2 servo motor, 400 V 3AC, 0.4 kW, 3000 rpm, IP65 with holding brake.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors"],"specifications":{"title":"1FL2103-4AF11-1MC0","Group Code":"R220","description":"SIMOTICS S-1FL2 Supply voltage 400V 3AC Pn=0.4kW;Nn=3000rpm M0=1.27Nm;Mn=1.27Nm Shaft height 30mm With hybrid connector AM21bit With shaft key, Tolerance N With holding brake Protection class IP65 with oil seal Matching drive SINAMICS S200","Product Group":"X0DJ","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)":"315.00 x 182.00 x 172.00 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/4d944bd304327e931790ce52e9805e12.pdf","sourceUrl":"https://sieportal.siemens.com/en-ae/products-services/detail/1FL2103-4AF11-1MC0?tree=CatalogTree"},"ai":{"faq":[{"question":"Which SINAMICS drive is the 1FL2103-4AF11-1MC0 meant to pair with?","answer":"The motor belongs to the 1FL2 family built for SINAMICS S200 drives; the encoder and parameter set are sized for the S200 platform, so substituting a different drive family means a re-commissioning pass rather than a plug-and-play swap."},{"question":"What compliance documentation comes with the 1FL2103-4AF11-1MC0?","answer":"The listing confirms RoHS conformity since 01-01-2018, REACH Article 33 reporting through Siemens' Reach Information channel, and an export classification of AL:N / ECCN:N, which keeps the paperwork light for standard industrial cross-border shipments."},{"question":"How does the 1FL2103-4AF11-1MC0 differ from a higher-power 1FL2 sibling at the same shaft height?","answer":"At shaft height 30 mm, the headline difference is rated power and speed: this unit delivers 0.4 kW at 3000 rpm with M0 = Mn = 1.27 Nm, so a higher-power 1FL2 sibling at the same frame would carry a higher continuous torque figure rather than a different envelope — the shaft height, brake, and encoder family remain common across the frame."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/1FL2103-4AF11-1MC0","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/1FL2103-4AF11-1MC0 when reusing this data.
