Lifecycle stage is recorded as current on the part file, so this is not a discontinued code — it remains an active SINAMICS S120 axis on Siemens' catalog. ## Encoder, brake, and the loop it sits in Feedback is an absolute encoder single-turn 22-bit (AS22DQC), which gives 4 million counts per rev — enough resolution that a tightly tuned SINAMICS S120 drive holds the micron on a well-staged axis. An integrated holding brake is part of the build, intended for vertical-axis and standstill-locking duty rather than cyclic dynamic braking. The shaft is a cylindrical D19x40 mm, and the housing carries IP65 protection. Both connectors are size M17 — the DRIVE-CLiQ signal plug and the power plug — keeping the cable bundle consistent with other 1FK2 axes on the same cabinet. ## Compliance posture and shipment handling The product class is C: manufactured/produced to order, not reusable and not returnable against credit — order quantities are firm. Carton size is 452 x 250 x 267 mm for one piece. ## Sourcing posture for an active 1FK2 axis Group code R220 and product group 9021 are the Siemens internal identifiers stamped on the nameplate for this servo motor, used to reconcile the PO line against the shipping unit.","metaTitle":"Siemens 1FK2104-4AK11-0SB0 Servo Motor, 1.27 Nm, IP65","metaDescription":"Siemens 1FK2104-4AK11-0SB0 SIMOTICS S-1FK2 HD servo motor, M0=1.27 Nm, 0.6 kW at 6000 rpm, IP65, absolute encoder AS22DQC, with holding brake.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors with Brake"],"specifications":{"title":"1FK2104-4AK11-0SB0","Group Code":"R220","description":"SIMOTICS S-1FK2 HD servo motor M0=1.27 Nm; PN = 0.6 kW at nN=6000 rpm (380-480 V); PN = 0.4 kW at nN=3000 rpm (200-240 V); with holding brake; degree of protection IP65; cylindrical shaft D19x40mm; 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":"1FK2 servomotors for SINAMICS S120","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/008731c70a1adc25b5a57c5eced6e5ef.pdf","sourceUrl":"https://sieportal.siemens.com/en-ae/products-services/detail/1FK2104-4AK11-0SB0?tree=CatalogTree"},"ai":{"faq":[{"question":"What are the headline ratings of the 1FK2104-4AK11-0SB0?","answer":"Stall torque M0 = 1.27 Nm, rated power 0.6 kW at 6000 rpm on a 380-480 V bus (0.4 kW at 3000 rpm on 200-240 V), IP65 housing, absolute encoder AS22DQC single-turn 22-bit, with holding brake."},{"question":"What compliance documentation does Siemens publish for 1FK2104-4AK11-0SB0?","answer":"No UL or IEC certification line is listed on the part file."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/1FK2104-4AK11-0SB0","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/1FK2104-4AK11-0SB0 when reusing this data.
