Continuous rated output is Pn = 0.4 kW at a rated speed Nn = 3000 rpm on a 200 V 3AC supply, with both the stall torque M0 and the rated torque Mn at 1.27 Nm — the stall and rated torques being equal means there is no speed-dependent torque gain envelope to size against, just a flat 1.27 Nm continuous from standstill to rated speed. With a 30 mm frame, plain shaft (tolerance N), no holding brake, and IP65 sealing with oil seal, this is the smallest-bore member of the 1FL2 family — sized for light-axis duty such as small feeders, labellers, and rotary indexers rather than the larger shaft heights reserved for conveyors and heavier positioning tables. ## Encoder, shaft, and the holding-brake decision The motor uses a hybrid connector that carries a 21-bit encoder (single-turn absolute) — the AS21-bit resolution gives roughly 2.1 million counts per turn, which is the level typically paired with SINAMICS S200's basic positioning functions for repeatable indexing without an external measurement system. This build ships without a holding brake; if the axis holds a vertical load or needs a fail-safe stop at zero speed, the brake has to be sourced separately within the 1FL2 frame family — a plain-shaft, no-brake build like this one is suited to horizontal axes or to applications where the downstream reducer provides its own backstop. IP65 with oil seal is the rating to confirm against washdown or cutting-fluid environments; the oil seal upgrades the base shaft sealing beyond the IP65 dry-side barrier, so the front shaft area keeps lube out of the housing on retrofit applications where the existing gearbox already handles its own oil retention. ## Compliance and how Siemens categorises this build Siemens has held RoHS compliance on this part since 01-01-18, and the listing carries the standard REACH Article 33 duty-to-inform flag — meaning the declaration pack is on file but the manufacturer will only release substance-of-concern detail against a buyer request rather than publishing it generically. Product class C is Siemens's own documentation: the unit is built to order (not a stock shelf item), is non-returnable, and cannot be re-utilised — a build-to-print configuration rather than a catalogue-line spare, which affects how the part is replenished and how warranty credits are handled if a unit is misordered. ## Where it sits in active production and how it is supplied Even so, the product class 'C' tag means every unit is built to order against the purchase order rather than pulled from shelf stock; lead time depends on Siemens's current build slot and is confirmed at quote time. Independent distribution typically quotes the line against the BOM quantity with volume-pricing and delivery dates cleared at RFQ rather than off a web-booking.","metaTitle":"Siemens 1FL2103-4AG01-0SC0 Servomotor, 0.4 kW, 1.27 Nm","metaDescription":"Siemens 1FL2103-4AG01-0SC0 SIMOTICS S-1FL2 servomotor, 200 V 3AC, 0.4 kW, 3000 rpm, 1.27 Nm, IP65, for SINAMICS S200.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors"],"specifications":{"title":"1FL2103-4AG01-0SC0","Group Code":"R220","description":"SIMOTICS S-1FL2 Supply voltage 200V 3AC Pn=0.4kW;Nn=3000rpm M0=1.27Nm;Mn=1.27Nm Shaft height 30mm With hybrid connector AS21bit Plain shaft, Tolerance N Without 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/77504f79059b5bc5b456830ca06eea7b.pdf","sourceUrl":"https://sieportal.siemens.com/en-ae/products-services/detail/1FL2103-4AG01-0SC0?tree=CatalogTree"},"ai":{"faq":[{"question":"Where does the 1FL2103-4AG01-0SC0 fit in the 1FL2 servomotor family?","answer":"It is the smallest shaft-height member of the 1FL2 family — 30 mm frame, 200 V 3AC supply, 0.4 kW continuous — and is built as the matched motor for the SINAMICS S200 drive.
