SIMOTICS S-1FK2 HD servo motor with M0 = 2.4 Nm static torque and PN = 1.07 kW at nN = 6000 rpm on a 380–480 V bus (PN = 0.75 kW at nN = 3000 rpm on 200–240 V) — a compact high-density servo with holding brake, IP65 housing, D19 × 40 mm keyed shaft, single-turn 22-bit absolute encoder AS22DQC, DRIVE-CLiQ plug M17, and M17 power connector. ## Power, brake, and feedback — what each spec decides The 2.4 Nm stall torque and 1.07 kW rating at 6000 rpm put this motor in the medium-inertia SIMOTICS S-1FK2 HD bracket — sized for dynamic cyclic loads such as indexing tables, packaging axes, and small-format machine tool spindles where the holding brake holds the axis at rest and the single-turn 22-bit absolute encoder gives the SINAMICS S120 a precise position read on power-up without a homing run. IP65 sealing on the housing with the DRIVE-CLiQ M17 feedback connector and M17 power connector means the motor survives splash and light washdown duty typical of food, beverage, and packaging lines, but the cable glands and connector interfaces still have to be seated and torqued to the Siemens cable spec to keep the IP65 envelope intact in the field. ## Compliance, packaging, and the BOM detail that matters The unit ships in single-piece quantity with packaging dimensions of 452 × 250 × 267 mm, which is what the receiving dock and the panel-builder's shelf footprint have to accommodate — the motor itself is heavy enough that a two-person lift and a quoted freight class matter more than the box dimensions, but the outer pack gives the integrator the slot size to plan around.","metaTitle":"Siemens 1FK2104-5AK11-1SB0 Servo Motor, 1.07 kW, Brake","metaDescription":"Siemens 1FK2104-5AK11-1SB0 SIMOTICS S-1FK2 HD servo motor, 2.4 Nm, 1.07 kW at 6000 rpm, with holding brake and DRIVE-CLiQ.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors with Brake"],"specifications":{"title":"1FK2104-5AK11-1SB0","Group Code":"R220","description":"SIMOTICS S-1FK2 HD servo motor M0=2.4 Nm; PN = 1.07 kW at nN=6000 rpm (380-480 V); PN = 0.75 kW at nN=3000 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":"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/5a97cd6c669858495e51952a23d46cd8.pdf","sourceUrl":"https://sieportal.siemens.com/en-ae/products-services/detail/1FK2104-5AK11-1SB0?tree=CatalogTree"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/1FK2104-5AK11-1SB0","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/1FK2104-5AK11-1SB0 when reusing this data.
