The motor is dual-rated: 0.4 kW at nN = 3000 rpm on a 380-480 V supply, and 0.2 kW at nN = 1500 rpm on 200-240 V. The first envelope is the SINAMICS S120 / S210 line-voltage territory; the second is the lower-voltage drive territory, so the same motor drops into both cabinets without a re-spec. Feedback is the AS22DQC absolute encoder, single-turn, 22-bit — that resolves to roughly 4.8 million counts per revolution, which is the resolution floor the current loop is tuning against. Anything coarser in this class shows up as a quantisation ripple you can hear on a slow traverse; 22-bit single-turn is the right starting point before you need a multi-turn gearbox encoder. Connection is DRIVE-CLiQ via the M17 plug for the encoder/digital link and a separate size M17 power connector — the digital feedback cable carries motor identity, encoder data and thermal model back to the SINAMICS drive, so parameter download and motor identification are automatic on first plug-in rather than manual entry. Shaft is D19 x 40 mm with feather key; IP65 on the housing is the sealing class for the body, not the shaft seal — a through-shaft application in a washdown environment still needs the front flange seal to match the IP rating of the rest of the machine envelope. Lifecycle stage is current and the product status is active — the motor is in normal production and not on a last-time-buy clock. The product class is C: built to order, non-returnable, non-reusable. That is standard for configured servo motors with specific encoder, brake, connector and shaft options, and it means the BOM line commits to the configured variant — swapping the encoder code or the connector size means a fresh build, not a stock substitution. Packaging is one piece per carton at 452 x 250 x 267 mm, and quantity unit is one piece — single-unit ordering is the procurement norm, not a case pack. Compliance: RoHS-compliant since 01-07-06 and REACH Art. 33 information obligation is active — the supplier provides the candidate-list disclosure on request, which is what a fab or medical line audit will ask for before signing off an incoming-goods batch. Export classification is AL:N with ECCN N_CNDU — no export licence required for the standard destination set, which simplifies cross-border shipments through independent distribution. ## Ordering line identity inside the Siemens catalogue Group code R220, product group 9021, product family ordering-data overview — these are the internal line identifiers that tie the configured motor to its price list and configurator output, so a purchasing system matching on group code picks up the right line on the PO.","metaTitle":"Siemens 1FK2104-4AF11-1SB0 SIMOTICS S-1FK2 servo, 0.4 kW","metaDescription":"Siemens 1FK2104-4AF11-1SB0 SIMOTICS S-1FK2 HD servo motor with brake, 0.4 kW at 3000 rpm (380-480 V) or 0.2 kW at 1500 rpm (200-240 V), IP65, DRIVE-CLiQ.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors with Brake"],"specifications":{"title":"1FK2104-4AF11-1SB0","Group Code":"R220","description":"SIMOTICS S-1FK2 HD servo motor M0=1.27 Nm; PN = 0.4 kW at nN=3000 rpm (380-480 V); PN = 0.2 kW at nN=1500 rpm (200-240 V); with holding brake; degree of protection IP65; shaft D19x40 mm with feather key; absolute encoder single-turn 22-bit (encoder AS22DQC); with DRIVE-CLiQ plug M17; power connector size M17;","Product Group":"9021","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":"Ordering Data Overview","lifecycle_stage":"current","Packaging Quantity":"1","Export Control Regulations":"AL : N / ECCN : N_CNDU","Packaging dimensions (L x W x H)":"452.00 x 250.00 x 267.00 mm","Compliance with the substance restrictions according to RoHS directive":"Since: 01-07-06","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/bcea71f03f01c9277d8641e45f4a66ca.pdf","sourceUrl":"https://sieportal.siemens.com/en-ae/products-services/detail/1FK2104-4AF11-1SB0?tree=CatalogTree"},"ai":{"faq":[{"question":"Who supplies 1FK2104-4AF11-1SB0 and how is it quoted for volume?","answer":"The motor is sourced through independent industrial-automation distribution against an RFQ; volume pricing and lead time are confirmed at quote time against the BOM quantity.
